If your pet is ever unfortunate enough to be diagnosed with cancer, this is the place to go. My dog, Henry and I have had an exceptional experience at MarQueen Veterinary Oncology Clinic in Upland. The front desk check-in ladies are always friendly, helpful and professional, and the clinic itself is clean and well run. During my initial referral appointment, Dr FitzPatrick explained my dog Henry's grade 3 mast cell tumor diagnosis clearly and honestly. He took the time to walk me through the prognosis, next steps, and all available treatment options. I appreciated that he was straightforward about what to expect while still being compassionate and supportive. We are now about six weeks into treatment, with weekly bloodwork and chemotherapy. One thing that has stood out is the consistency of care. Veterinary Technician Shannon always comes to the waiting room to take Henry back for his treatments. I truly appreciate seeing the same person each time. Shannon is kind, patient, and knowledgeable, and Henry is clearly comfortable with her. Henry is feeling pretty good overall, even after his chemotherapy sessions. Seeing him do well has been a blessing and has helped reassure me that his treatments are helping. While I understand the prognosis is serious, I feel confident that Henry is receiving the best possible care here in order to extend his quality of life. I'm very grateful for the level of care Henry is receiving and I would highly recommend this clinic to anyone needing Oncology services for their pet. read more

Please read this before coming here. I brought my very sick senior yorkie in yesterday morning around 10 am since we were referred here by another EMERGENCY hospital that was not equipped for an ultrasound which was what my baby needed. We didn't get vitals until an hour later and then once we're in a room an hour after that to talk to a dr we waited for another 2 hours and then the dr tells us they'll go ahead and do the ultrasound and said it will be done anytime before 6pm because we were a "walk in" THIS WAS AN EMERGENCY SITUATION and my dog was actively dying!! Mind you we got there at 10 and the whole time his gallbladder was ruptured and leaking and there was no sense of urgency at all. Not to mention the doctors attitude was so cold and casual I believe her name was Zamora. Once the ultrasound was done around 3/4 pm we waited and waited and waited still for them to talk to us about the results probably over another hour or two we were waiting all for Zamora to come in very causally once again and say his gallbladder is the cause of all this and it has mucocele which is causing inflammation and he needs surgery. She just came in, opened her laptop and told us the findings. She didn't even SHOW us the ultrasounds or go in depth like every other place I've been to. You would think for $1,900 they would do that but no all they care about is the money and it shows. After she told us the news I say when are you doing the surgery and she responds "right now I'm holding the surgeon here" and then quotes us 17k minimum and 20k maximum for this surgery and hospitalization. So we're over here panicking and stressing because he's actively dying and they're trying to rob us and on top of that giving him a 50/50 chance of survival. Me and my mom were in panic trying to find another way another place to just save my dog since this is just not realistic for an average person but they seem to think otherwise. Anyway we asked if we could have a moment to discuss and make phone calls and throughout this whole time suddenly they were readily available and not busy and kept coming in to the room asking if we've made a decision yet and then at one point come in to say "so you're not doing surgery then? So I can send the surgeon away" how could they say that when all they had done all day was making us wait and suddenly it's urgent only when it comes to getting money!! And every time I asked a question regarding his rupture and gallbladder the lady kept saying "let me ask" "let me check" because the doctor that was just there had already disappeared!! We ended up making a phone call to an amazing vet hospital in Tijuana called "hospital de Mascotas SAJI" we called them and they said to bring him in as soon as we could so we got our baby back from this place and declined the surgery which they did not look too happy about. On the way to TJ, the vets over there were asking for all his lab work in order to be prepared for his surgery and when I called marqueen for his records and ultrasound results to be emailed to me they took over an hour and I had to call 3 times! said the doctor needs to sign off even though we were just there and we're entitled to our records. We made our way to Tijuana Mexico where they did a quick ultrasound that took minutes as soon as we got there and then proceeded with surgery. Unfortunately our baby didn't make it I only wish I would have come to this place in Mexico sooner. If only MarQueen treated this as an emergency as it was after all it's in their name and did tests sooner perhaps we could have gotten him to his surgery sooner and he would have had more of a chance since he was too far gone by the time the whole day of waiting around has passed. To everyone reading this I suggest you find a vet in Mexico or go to this one for a pet emergency or even any need. They care so much more about your pet for not even a fraction of the cost and on top of that they were COMPASSIONATE. I was also quoted $1,800 in Mexico for the same surgery, medication and hospitalization if my baby had pulled through. read more

This single star is too much for Eugenia Nieto, DVM. I arrived 10/25 with my beloved Albert, a 15 year old terrier, per a general vet's instructions. He had been ill with a constellation of symptoms. His demeanor had slipped from lively & bright eyed to depressed & disinterested though he still tried hard to keep the daily pace. I was very worried. Albert was the dog every vet in his life expected to live into his 20's. New vets were astonished at his age as he was so lively & energetic AND HEALTHY. He was sweet to all, even at the vet. All staff delighted in this hairy bundle of joy. Marqueen was very busy & Dr. Nieto was clearly harried when she entered the room. She seemed put off. Albert didn't have visible wounds she could easily assess but I made sure she knew I was referred due to Marqueen's ability to fo extensive testing. Nieto gave Albert a cursory exam. She noted he had a scratched cornea (already being treated), claimed he had severe dental disease (he was due for a dental which was never deemed "severe", and lastly, THAT ALBERT WAS AN OLD DOG. I persisted in trying to obtain diagnostic testing for internal issues but Nieto declined. And so did Albert. My general vet ordered an abdominal ultrasound which showed the appearance of an inflamed stomach lining plus a small mass on his adrenal gland. By now Albert had more general vet trips in a few months than he did his entire life. Primarily this was to treat his eye which wasn't healing. He was miserably ill in general, had worsened significantly from Nieto's dismissal, & now would shake at every vet clinic. I held him tightly but he had had enough. He was scared. It was unbearable watching this mighty, funny, hyper, loving little dog displaying pain posture, being listless, losing the light in his once bright eyes. Everyone loved those big brown eyes. On December 22nd I was back at Marqueen with Dr. Choi. She listened. She took action. I left Albert all day for diagnostics & returned in the early evening to discuss results. Dr. Choi came in & I could see by the compassionate look on her face that the news wasn't going to be good. And it wasn't. Albert was going to die. He had many problems. The worst was now the now enlarged adrenal gland with the mass also enlarged. There was also a very large mass in his primary abdominal vessel (caudal vena cava). So large, in fact, it was too dangerous to biopsy. It likely grew from the adrenal mass. Dr. Choi told me to take him home & give just love him. There was nothing that could be done. Oh my god, this is so painful to write... I held on to him a little bit longer but knew it was time to let go. He was suffering but was a little gentleman the entire time. I said good bye on Jan 30th & haven't stopped crying. HE DID NOT DESERVE EUGENIA NIETO'S CRUEL DISMISSAL. SHE CAUSED HIM UNNECESSARY SUFFERING. I've said good bye to many members of my fur family in my life but never due to blatant negligence. NEVER UNTI NIETO'S BLATANT NEGLIGENCE. In my grief I grew angry and called Marqueen to report Dr. Nieto's indifference & negligence. I was told the "manager" is PEGGY OLSEN. She responded with a frigging e-mail, not even a personal call of condolence. She defended Nieto, of course. Peggy Olsen was cut from the same callous cloth as Eugenia Nieto. She wrote a perfunctory "sorry about your dog" line & proceeded to defend Nieto. There will be more to come about this entire despicable, inhumane situation. In the meantime, DO NOT ALLOW NIETO NEAR YOUR PET! Make sure when you go in that you know who is in charge and have their contact info. While you wait (& wait & wait) Take pic of the business license & all other important fix that must legally be displayed. I read that Petulant Peggy the inadequate "manager" will 86 you if you make a public complaint. Well, Peggy, that's fine with me! I've already connected with better alternatives. This is not the Marqueen of yore. I hope the good veterinarians I met and the owner review the persistent problems so that the Nietos & Peggys don't drive them further down. The good doctors don't deserve the fallout. Peggy, on behalf of my little love, I'm giving Marqueen a Google review as well. Rest in Love & Peace my sweet boy. read more

We had to bring our beloved 15 yo Aussie in due to her collapse in our home, the staff was very sweet and professional, unfortunatly we had to make the decision to have her escorted to the rainbow bridge. but again the staff was understanding and supportive, thank you Marqueen staff .you helped make difficult decision easier to manage. read more

It's not the ideal way to visit this hospital but due to my dog's emergencies, I've had several visits here within the last six months. Yes, it can get expensive but this is an emergency hospital- they are equipped with all the necessary diagnostic tools. Some services can cost a lot more than your day vet. But some services like getting an ultrasound is cheaper than your day vet because they have the staff who can read results and the equipment on site. You visit this hospital when your normal day vet is unable to handle the emergency. My normal day vet ran blood work on my dog and the levels were toxic in the liver. I took him to his ophthalmologist who recommended he be taken into this hospital immediately. All of the doctors here are very well educated and the techs are detailed when taking an intake. I already had blood work from my day vet and the doctors here will take that so you're. It running another panel. I cannot imagine being in their shoes seeing pet related tragedies day in and day out. I was able to prepare myself due to the correct diagnosis I received here. Unfortunately my dog passed away due to being in the late stages of having liver cancer. I had another vet emergency where Marqueen was closed since it was past midnight back in July. That hospital supposedly ran an ultrasound on my dog. I wish I had it done here because Marqueen is so much more competent. I'm just grateful for the sympathetic staff who did their best to provide excellent care for my dog. I've had to wait three hours during one of my visits before because they work on triage. I've also had the staff take my dog immediately due to the dire circumstances. I know it can feel stressful and hard to wait at length but they really know their stuff and how to triage accordingly. When I did wait for a while, I was given a private room to wait with my dog. Thanks to Marqueen, I found out my dog had liver cancer and I was able to spend the week with him as much as I could before my dog told me it was time for him to go. We had to bring him back here in an emergency visit and he was going so fast they brought us back into the emergency operating table to say goodbye so I can see my dog and he can see us before he left the world. The staff gave us the time to cry and prepared his body to take home with us so our other dog can see his body and process that the brother she spent all of her life with, was gone. The staff brought him out to the car because we were going to have him buried rather than cremated. They provided a bag and warned us that his body may excrete fluids and the bag will help so the fluids don't leak. Everyone was compassionate and supportive during one of the most difficult times I ever had to go through. read more

MarQueen Pet Emergency and Specialty Group - Samson back in June. RIP Samson (11/08/2025). - Veterinarians Near Me - Upland, California

They are a premium veterinary with premium services. I never thought my sick cat got any better care. I would be very worried about the cost though. I didn't feel acutely they ovee treated for profit or recommended anything not necessary. However I did feel they are on the more expensive side. All costs are paid and secured up front. So be prepared to pay. I would hope you have a pet insurance without limits or it be a very hard decision for many people that come here. Regardless they saved my cats life and that is priceless. read more

Over Valentine's Day weekend, our cat Luna needed emergency surgery, a situation no pet parent ever wants to face. The team at MarQueen in Upland was incredible from start to finish. They acted quickly, communicated clearly, and treated Luna with genuine care and professionalism. During an extremely stressful time, they made us feel supported and informed every step of the way. Luna is now home recovering, and we're deeply grateful to the doctors, surgeons, and nursing staff who took such good care of her. If you need emergency veterinary care, this is a place you can trust. read more

The staff is always friendly and helpful. The clinic is also clean and the waiting area is comfortable. Dr. Durtschi is an incredible cardiologist. She is knowledgeable and made it incredibly easy to understand Sara's condition. read more

I brought my dog in because she had been vomiting all day and couldn't keep any food or water down. I knew something was very wrong, so I rushed her in for an emergency exam. Even though they were very busy, the staff started helping her right away and were always kind--I never once felt overlooked or unimportant. Dr. Polina quickly figured out the problem with an X-ray--my dog had a foreign body and needed surgery as soon as possible. Throughout the night and into the next day, Dr. Polina, Dr. Zamora, and the rest of the staff continued checking on her. Now my dog is healing, and I'm so grateful for their quick action, compassion, and expertise. Pumpkin and I truly appreciate everything they did. I highly recommend bringing your pets here if you want a team that genuinely cares and provides exceptional care. read more

The people at Marqueen told me my 10 year old male cat had a urinary obstruction and needed a special kind of surgery I told them that I couldn't afford the $6,000 that it would cost to give him surgery and asked if there was anything else we could do. They came back about 10 minutes later with a quote for a $3,000 "band-aid" hospital stay, and I told them I couldn't do that either. They proceeded to tell me that this was a serious issue, and that if I couldn't afford to pay for his care now, then I should just put him down. I ended up paying around $1,000 for them to drain his bladder and give him more time. I stayed up all night and all day the next day looking for a place that would take him for this special surgery at a discounted cost. I finally found a place, and they called me that evening telling me that he didn't even need the surgery. He just had a UTI, and it was totally treatable. The people at Marqueen wanted me to murder my 10-year-old cat over a UTI. I will complain about this place until the cows come home. I can't believe they told me to put down my otherwise healthy cat, who was only 10 years old at the time, over a UTI. My Garfield is now healthy and thriving years later. It breaks my heart thinking of how many pets have been put down at their recommendation when it was not at all necessary. I really hate this place. read more

MarQueen Veterinary Specialty Group saved my dog Brooklyn's life. He was diagnosed with a severe, sudden-onset autoimmune disease (IMHA), and it was through their care and intervention that we got through one of the hardest experiences I've ever faced. Brooklyn required two blood transfusions to stabilize. From the beginning, the team kept me consistently updated, and whenever I needed additional information, they made themselves available without hesitation. During his 5-day hospitalization, they allowed me to spend a significant amount of time with him. I never once felt rushed or like I was in the way. That mattered more than I can explain. What stands out to me is how Brooklyn responds to them now. Even after everything he went through, he isn't afraid to go back for checkups. He's still low in energy, but he wags his tail vigorously when he sees the staff. That says a lot. Everyone at MarQueen has been excellent, but I want to especially recognize Jess. Her warmth and compassion made a real difference during an incredibly uncertain and frightening time. Brooklyn is my heart dog. I love him deeply, but I was also faced with the reality that I didn't want to prolong his life if he was suffering. The doctors, especially Dr. Zamora, took the time to talk me through everything with patience, compassion, and thoughtful guidance. I never felt pressured--just supported. It's now been almost exactly one month since his diagnosis, and Brooklyn is continuing to improve. His ongoing care is with Dr. Yi, who I now see about once a month. She is clear, responsive, and genuinely a joy to be around. Her energy makes a difficult situation feel more manageable. When you're going through something this serious, the people caring for your pet matter just as much as the treatment itself. At MarQueen, you get both skilled medical care and truly compassionate support. read more

Sat for an hour and a half for them to give me absolutely no information, but told me they wanted to charge upwards of $1700 for them to do full panel blood work and X-rays. I mean, I could tell u what's wrong after doing all that too. But the "doctor" came in for 3 minutes TOPS, and said "her foot hurts and is swollen". No duh, I told u that when I got here. Wasted about $500 and a total of two hours here and my cat isn't doing ANY better. Now we go somewhere else. Don't come here. Do not come here! read more

My fur baby Kobe needed emergency services, and Marqueen Veterinary Hospital was truly the best place we could have gone. Kobe was vomiting, unable to keep food or water down, and clearly in pain and discomfort. The staff immediately checked his vitals, got him admitted, and treated us with such care and compassion. It turned out Kobe had eaten something that was moving through his intestines toward his colon. What I appreciated most was that the doctors didn't rush him into unnecessary surgery. They carefully monitored him and determined it wasn't a full blockage and that he'd likely pass it on his own. After three days of hospitalization, Kobe was getting a little depressed (& mama too), so the doctors recommended I take him home, assuring me I could bring him right back if anything changed. At home, he's eating a little more, pooping a little more, and we're just waiting for him to fully pass whatever he swallowed. Our fur babies are family, and they deserve the very best care. I can't thank Dr. Roth, techs Desiree and Megan, and the entire Marqueen staff enough for their professionalism, kindness, and dedication. Highly recommend this hospital for anyone who needs emergency or specialty care for their pets! read more

Our Cat Pearl was declining over the last month, and when I called MarQueen (referred by our vet) they were compassionate about our situation and made our experience comfortable for us and our cat. Sadly, she went over the rainbow bridge and will rest in peace. Dr. Strasser was kind and helped us say good by to Pearl. The staff was also kind, professional and caring about our cat's situation. I highly recommend their services. read more

WORST PLACE EVER TO TAKE YOUR PETS. DONT COME HERE. Came on a Tuesday evening to put my cat down and they come up with all these crazy prices to just do the bare minimum. Just for an exam, $175. For euthanasia, $155 & to even leave my poor lifeless cats, they were going to charge $120 or more. NOT EVEN INCLUDING cremation or taking anything home, they were going to charge almost $300. I don't understand how people can keep coming here and giving them the business. These are actual lives and I can't believe these heartless people/Dr. Rest in peace, my sweet Pumpkin girl. I NEVER write any yelp reviews or any negative comments on any business. But this place easily takes the cake. I will never recommend this place to anyone. This is something I will never forget nor my family. read more

I almost didn't go to this hospital because of a warning review about Dr. Zamora, and now I know why. My dog suddenly stopped walking, and she was one of the few vets available at that time of night. From the second we arrived, she was condescending, rude, and dismissive, talking down to me even though I clearly explained the facts, my dog had jumped off the couch and fallen. She insisted that because my dog had "knuckling," it had to be neurological. She immediately brought up extremely rare diseases such as discospondylitis, pushed worst-case scenarios, and suggested euthanasia. She spoke only slightly more politely to my dad, and treated me like I didn't know anything, although I stayed respectful and asked relevant questions. I wound up more correct than this "vet" with a medical license. We saw three other vets afterward, and every single one disagreed with her. All my dog needed was a very common TPLO surgery, and now he's perfectly happy and back to normal. This isn't just bad bedside manner, it's dangerous, reckless, and completely unacceptable. If you love your pet, get a second opinion and stay far away from Dr. Zamora. read more

We can't thank Marqueen Emergency Vet in Upland enough -- they literally saved our dog Sunny's life. Sunny had stopped keeping anything down, and an X-ray revealed a large mass. It was a dire situation, and we were terrified we might lose her. We know we can be crazy high-maintenance pet parents, but the entire team was so incredibly patient and understanding with us throughout the whole process. From the moment we walked in, everyone was professional, compassionate, and efficient. Dr. Mohammad Ibrahim performed emergency surgery and successfully removed a massive 3 1/2-pound tumor from Sunny's liver. He truly saved her life and prevented what could have been a tragic outcome. Dr. Ibrahim is our hero! A special shout-out to Casey and Alicia for their kindness and support during such a stressful time. The entire staff at Marqueen went above and beyond (Dr Queen, Dr Strasser, Dr Yi, Dr Travis) - I am probably not including everyone ....that treated Sunny (and us) with such care and expertise. If your pet is ever in an emergency, we highly recommend Marqueen Emergency Vet in Upland without hesitation. They are truly lifesavers! read more

This was one of the most traumatic experiences of my life, and it didn't have to be. My elderly dog was brought in for sudden lung issues and ultimately had to be put down. While he was alone in the back, scared and audibly whimpering, staff were laughing and joking within earshot. I was left sitting there, terrified and grieving, while no one communicated with me or showed the slightest concern. I had to walk back myself just to see my dog because the staff simply didn't care enough to bring me to him. That moment I realized my dog was dying alone while people laughed nearby will stay with me forever. They showed they do not care for their patients. I have been crying for weeks over the pain this place caused. Losing a pet is already unbearable. Being treated with such coldness and disrespect during that moment was almost inhuman. If you expect compassion, dignity, or empathy when saying goodbye to your animal, do not come here. read more

One week ago, we unfortunately had to make the difficult decision to put our dog Simon to sleep due to circumstances outside of our control. When we called MarQueen Pet Emergency and Specialty Group, the compassion was immediately felt and heard over the phone. Once we got there, one of their staff assisted in carrying Simon out of the car as he was unable to walk at the time. He was immediately taken back to be assessed. Dr. Strasser was the emergency veterinarian there that night and he calmly, compassionately, and honestly explained our options in detail. Thanks to his transparency, we were able to come together as a family to get through the next steps together. He was truly caring during his time with us. The staff was amazing - I wish I could remember exactly who it was that helped us, but they were all phenomenal. One of the front desk staff assured us that we could take our time saying goodbye to Simon and even allowed extended family who loved Simon as well to bring him one last meal and to say goodbye. They continued to assure us that we should not be in any rush and to take our time. Our family's last few moments with Simon were filled with lots of tears, but also lots of love and snuggles as MarQueen's staff so graciously and generously provided the best experience they could under the circumstance we were in. I'll never forget the tenderness and kindness that was shown to us. When it was time to say goodbye to Simon, my husband and I stayed with him while Dr. Strasser got started on the process. He calmly and quietly explained everything he was doing and once it was all over, he offered us comforting words and also gave us some extra time to be with Simon one last time. When we were ready, two other staff members came in and told us how sorry they were for our loss and compassionately took our pup. We picked up his ashes yesterday after MarQueen called us and told us Simon had just arrived back at their clinic. We got some pastries for the staff and Dr. Strasser as a thank you and while the staff was different from last week, all of the ones we encountered yesterday were equally as kind, understanding, and compassionate. Thank you, MarQueen, for helping our family in this difficult time and for helping our Simon cross the rainbow bridge. We'll never forget the love and care you showed him in the short time you knew him. read more

I've tried a few vets before finding this one, and now I wouldn't go anywhere else. They treated my stray kitten like royalty!

My baby Benji accidentally ate some rat baits after the wind broke the door of our garden shed. We called our vet and they referred me to MarQueen. We rushed Benji there and was seen right away (before my paperwork was done). But the main reason i want to share my thoughts & give them 5 stars review is because of Dr Strasser. Ive been having fur babies my whole life and have seen so many vets before. Dr Strasser is the only one that I feel TURLY genuine and you can tell he really loves animals & people. Thank you, Dr Strasser, for taking care of Benjamin. We really appreciate you! read more

Our journey with MarQueen Pet Specialty began when our Doberman was diagnosed with diabetes by our local veterinarian. They recommended we see a specialist in hopes of managing the disease properly and giving our dog the best chance at a healthy life. MarQueen was that recommended specialist, and Dr. Polina was assigned to our case. After the initial visit, we discussed a treatment plan. During that appointment there was immediate fear-based messaging about how 80% of diabetic dogs go blind within three months and how we should proactively schedule with an eye specialist. It felt heavily pushed. I declined the referral at the time, and for context, my dog lived with diabetes for over a year and never went blind. We paid a very expensive one-time specialist fee that was presented as providing ongoing guidance, communication, and follow-ups. Unfortunately, that support never materialized. The only time communication happened was when I reached out first. At one point my dog scratched her eye on a branch. I brought her in to have it examined. Once again the recommendation was immediate surgery. Instead, I treated the scratch with ointment. It healed completely without issue. Another frustrating issue was getting insulin approved. Insulin, the medication my dog literally needed to survive, often required jumping through hoops. Instead of simply authorizing the medication, I was repeatedly told visits were required so they could run blood tests, urine tests, and other diagnostics. Each visit was close to $1,000, only to be told the same thing each time. Availability was also a constant issue. Dr. Polina frequently seemed to be unavailable, on vacation, on sabbatical, or otherwise difficult to schedule with. Eventually, after spending thousands of dollars and doing everything we could to give our dog the best quality of life possible, we lost the battle with her illness. When I notified Dr. Polina that my dog had passed, the response I received felt cold and generic, like something copied and pasted. Ironically, when you're on hold at MarQueen the recording proudly talks about how much they care and how special their level of care is. In my experience, that simply wasn't the case. To be fair, a few of the emergency doctors we encountered showed genuine compassion. One even suggested we use Chewy for medications after seeing how much money we had already spent. Those individuals were the exception. But overall, my experience with MarQueen Pet Specialty felt like constant upselling, unnecessary procedures, and poor follow-through on the support that was promised. After what we went through, I cannot recommend this place. If you're looking for specialty care for your pet, my honest advice is: find another option. read more

I have a 13 year old house kitty that doesn't really like people or being handled. She started limping so I brought her here. They were wonderful! Dr. Tiffany Steir was so kind and knowledgeable. My kitty let her examine her and didn't hiss or scratch at all. It turned out to be a sprain so my kitty is OK. Everyone from the front desk staff, to the tech, and the doctor were all wonderful. The environment is super clean and calm and spacious. I highly recommend them and would definitely come back again. They tell you the price ahead of time so you know what to expect and can decide on a treatment plan. Very fair and excellent care. read more

Save your time, money and resources. $8K later and zero answers to why our dog has internal bleeding. They overcharge for very basic things and don't have great bedside manner. They tell us if we want more tests done, no answers are guaranteed (AGAIN). They had our dog for a little over a day and gave him back to us in the same way we brought him, just "hydrated" and a blood transfusion later, which our original family vet said was what he needed and this place-- specifically Dr. Nieto-- said we had to wait to get test results back first aka taking our money first for tests that did nothing. When it was time to pick him up we asked why these tests gave us no answers after they said they'd know more, all we got was "we just don't know." Joke was truly on us-- tests and doctors gave us zero answers. If I could give zero stars, I would. read more

This place took care of my dogs on two separate occasions. One was kidney failure and a few other things from eating a sago palm seed and the second was a bad case of old age hitting him hard.

I brought in my cat to MarQueen because he had diarrhea for about 3 days, and began to throw up. I was afraid he got into the Christmas tree water. I called ahead and was told it would be a long wait because they are an urgent care vet clinic. I completely understand and appreciated the heads up. I brought a book to read while we waited for the vet. The whole staff, (from the front desk ladies to the vet tech, and the vet herself) were very helpful and friendly. The place is nice and clean and there were no patients waiting in the waiting room when we get there at 8am on a Wednesday. We waited a while to be seen, but eventually we were told what our options were and based on that information, we proceeded with outpatient care. Thankfully, our cat recovered with the meds he was prescribed after a couple of days. We felt the price was reasonable for the care our cat got, and at no point did we feel forced to go with the most expensive option. I appreciated and was very pleased with the services MarQueen rendered our pet. I recommend them. read more

My family is still reeling from the nightmare we endured at Marqueen Vet Emergency Hospital. Our dog was urinating frequently with visible blood in her urine, so we rushed her there on a Saturday night expecting urgent, compassionate care. Instead, we faced over 2 hours of unexplained waiting in an exam room, bumped repeatedly for "more urgent" cases without a single staff member informing us why. Only one doctor was on duty, and transparency was nonexistent. When the doctor finally appeared, he never physically examined our dog--he relied solely on the tech's chart. He ordered a urinalysis and suggested additional tests, but we waited another 45 minutes in the lobby for results. Then came the devastating, unprofessional bombshell: he opened his laptop in front of us, read the results aloud without any sensitivity, and declared our dog had diabetes with a glucose of 1000 mg/dL. He launched into a grim monologue: * "She has 3-6 years to live." * "She'll go blind." * "Forget family vacations--she'll need insulin shots every 12 hours and constant care." None of this aligned with our dog's behavior--she'd been acting completely normal, with zero symptoms of illness. When my son asked for a confirmatory blood glucose test, the doctor dismissed it with, "I can do it, but she still has diabetes." He kept pushing a $500 urine culture despite our distress. We left in tears, terrified our healthy dog was dying. The doctor's final words? "She looks good--she can wait 10-12 hours, but she needs insulin." How does a 1000 mg/dL glucose level equal "looks good"?! No compassion, no clarity--just fear-mongering and upselling. The next morning (Sunday), we took her to Chino Hills Animal Hospital. They saw us immediately, ran a proper blood glucose test, and confirmed: NO DIABETES. Normal glucose. Just a UTI. She's now on antibiotics and thriving. The relief was overwhelming, but the trauma from Marqueen's incompetence and cruelty lingers. Marqueen's failures: * Zero bedside manner - delivered life-altering news like a robot. * No diagnostic rigor - urinalysis alone isn't enough to diagnose diabetes. * Waste of time and money - hours of waiting, fear, and a bill for misinformation. Do NOT risk your pet here. Chino Hills Animal Hospital restored our faith in veterinary care. Marqueen nearly destroyed ours. read more

This isn't an easy review to write, but I want to express my gratitude to the staff at MarQueen Pet Emergency Hospital for their compassion during one of the hardest moments of my life. We came in through the emergency side, and although the outcome was heartbreaking, the care and empathy shown to both me and my pet made a difference. The team was gentle, respectful, and gave us the time we needed to say goodbye. It's not a place I ever wanted to be, but I'm thankful it was them who helped us through read more

My dog had what seemed to be an allergic reaction. He was breaking out in bumps and developed a rash. I had initially made an appointment with his regular vet but since it was getting worse I decided to take him to MarQueen as it was already around 9pm. The staff is very friendly and professional. They got us checked in and into a room where my dog was able to lay down and try to relax. They were very up front about the wait time, which as an emergency animal hospital you should understand wait times can be long and may vary. Thankfully the doctor was able to see my dog sooner than expected and prescribed the meds he needed. We got checked out and had meds much quicker than I thought. I'm very thankful for their service as my dog was able to start getting back to normal much sooner and didn't have to wait 2 more days to see his regular vet. Parking is ample and the business is very clean and has plenty of room for pets who might be a bit anxious/nervous to have space to themselves. Thank you so much for taking care of my dog and getting him feeling back to normal! read more

All they try to do is charge you for treatment that your pet doesn't really need. They wanted to put my dog to sleep when he was having sob. I took my dog home and he was fine the next day. They were going to kill my perfectly healthy dog. Shame on the Vet. read more

$15,000 dollars for my puppy's broken leg. And that's not even guaranteeing he would walk normal ever again. What a heartbreaking experience. You guys are really taking advantage of people at their lowest. I think you're absolutely disgusting charging that much money. read more

Iv had good and some really bad experiences here with in the last 10 months Iv been here multiple times with 3 of my dogs 2 of which were at the end of their lives. Some of the vets are knowledgeable and have great bedside manner one other in particular does not. The experiences putting my 2 older dogs to rest were both very different here the vet with my first dog explained everything in detail that was going to happen. With my other pet I stated I was having second thoughts and the vet said I wouldn't most dogs would have responded to treatment as she reached over to inject him without explaining the process's, how it works or what was about to happen. On another note if most dogs would have responded to treatment and he didn't, why did you keep my dog in that condition for 6 hours? So yo could charge me over 2k read more

I can't say enough good things about this clinic! They treated my senior dog like family, took time to explain every detail, and followed up afterward. You can tell they really care about animals :) read more

MarQueen was the third Emergency Vet we went to. The first one couldn't take our dog in at all, the second had a 4+ hour wait and told us we couldn't leave the parking lot if we wanted to be seen. It was 5:45am and the earliest they could take us in was 10am. We were not going to wait that long. Luckily, after trying another hospital, they referred us to MarQueen. We arrived there around 6:15am. When my husband called, they immediately took down our dog's information and asked us how soon we could be there. We were at another emergency vet in Ontario and drove over to Upland. Once we arrived, they took her in right away. She had a preliminary exam and then they recommended X-rays. The X-rays showed that she would need an endoscopy. The tech who performs the endoscopies was out as it was her day off, but came in to perform the procedure on our dog. They gave us a couple options and two different prices. We were able to leave our dog there and they would call us when she was ready to be picked up. We got a call around 10:30am that we could pick her up within an hour; that would give her time to wake up. Well around the same time our dog was ready to be picked up, the emergency vet in Ontario finally called back and said they were ready to see us. *sigh* . The vet had a chat with us, showed us the photos from her endoscopy and then another tech came and told us about her medications. The following day, they called us to ask how our dog was doing. Overall, we received great service from start to finish. Hopefully we don't have to visit another emergency vet in the near future, but if we had to, we'd definitely come here again. read more

The staff and doctors at Marqueen are absolutely amazing. We brought our one-year-old dog Jo into the emergency room with a life-threatening condition, and everyone was incredibly kind and patient as we made difficult decisions about her care. Over the past year, we've received continuous services from Marqueen, weekly and monthly follow-ups for Jo and they have truly become like family to her. She is always so happy and excited to greet the staff when we walk in, which is not typical for a dog at the vet! They have taken such excellent care of her, and we couldn't recommend Marqueen more highly read more

The vet tech Giselle that attended us had a very conferencing tone and look. She gave us her back as she was asking us questions and did not seem to care about our cat. We took In our cat due to having a lesion that appeared the day prior and it had started to bleed - there was no first aid care rendered or any care provided by the tech. Her tone was condescending as if WE were bothering her by being there. The wait time was very long - 2+ hrs. We were not check on during the 2 hr. We were there there - they only check in on us after we ask for follow up - if not they would not come to see our cat. Once the vet came in she provided a recommendation of treatment which we accepted. The vet tech again came back and provided us the form to sign for payment - took our cat and said - "go to the front to pay once I confirm the funds are there we'll go ahead and give the medication" That comment was offensive and uncalled for - we had already agreed to treatment and were aware of the amount due - my daughter and I took it as we would not have the money to pay for the treatment - the tone and look was very condescending and offensive. We Will not be returning to this location - we usually go to VCA however when we called our vet recommended this ER. read more
