    Thank you for making Mavis's first visit such a great experience. The entire staff was incredibly friendly and attentive. Dr. An provided valuable, breed-specific preventive care advice for Mavis, which I truly appreciated. Scheduling the appointment was also quick and easy.

    Technicians showing so much love to our fur babies

    A long overdue review for a truly exceptional veterinary clinic. I have been bringing my Pomeranian, Maltipoo, and Poodle to Sunset Vet for some time now, and I am consistently impressed by the level of care and compassion shown by every member of the team. From the moment you walk in, you can feel that the staff genuinely love animals and treat each pet as if they were their own. Dr. An is one of the most dedicated and thoughtful veterinarians I've ever met. He takes the time to thoroughly explain any concerns, answer all of my questions, and most importantly, he always follows up to check on how my pets are doing after a visit. That level of attention and care is rare and deeply appreciated. Over the years, I've been to many veterinary offices, but Sunset Vet is truly in a class of its own. Their professionalism, kindness, and consistent follow-through make all the difference. It's clear that this clinic prioritizes both the health of their furry patients and the peace of mind of pet owners. I'm so grateful to have found a place where my pets are not only well cared for but genuinely loved.

    We loved Dr. An and his staff!!! They were so professional and so caring! We appreciated he wasn't pushy for certain services. He was gentle with the dogs!! Highly recommended!! They are definitely our new vet!!

    Stoney being curious

    Thank you Dr. Phil and everyone working there!! Stoney needed a check up and he was very well taken care of. The staff and Dr are all incredible. I live about 30 miles away and I don't mind making the drive out to Diamond Bar for Stoney to be seen. My previous dog was seen by Dr. An for many years. I spent $$$$ at other vet locations who misdiagnosed Tubby, and charged me ridiculous amount of money for medication. When I finally changed to Dr. An at another location he was working at, he wanted me to try out a different type of food and simple methods to see if things would change. I knew if I had another pet after Tubby, he would be the veterinarian for us again. Thank you!!

    Best Vet clinic I've ever been to. Love how they call pet parents "mama"! Staff are compassionate and friendly and Doctor is kind and very professional. I'm so glad we found this clinic!

    Thank you for everything  We all tried our best.

My pug had stopped eating, and we were very worried he may have swallowed something. The veterinarian quickly took the time to examine him carefully, explain everything clearly, and make us feel at ease. What really stood out was how efficient and knowledgeable the team was. They were able to identify the issue quickly, provide treatment the same day, and answer all of our questions with patience and care. Thanks to their help, my dog was feeling much better almost immediately and started eating again as soon as we got home. The pricing was also very reasonable compared to other places we visited, and the whole process felt smooth and stress-free. It's clear that the staff truly care about both pets and their owners. I'm so grateful for the excellent care we received and highly recommend Sunshine Veterinary to anyone looking for compassionate, honest, and reliable veterinary care.

I've brought my dog here twice, once for a wellness exam and the other for a vaccine. The first time I think I waited about 30 minutes since the vet was in surgery according to the front desk, which is fine, except it felt like our appointment was super rushed. He quickly looked at my pup and was about to end the visit before I asked if we could get labs done and ask him a few questions about my concerns. He didn't once ask me if I had any concerns, just said she looked good. I thought it was strange that he didn't suggest labs considering she was a new patient. My dog was 10 years old at the time, so labs should have been suggested considering she is a senior. Anyways, they ended up giving me a discount because of the wait. However I don't think that should have meant a discount in quality of care too? My biggest gripe is the lack of communication. Every vet I've taken my dog to has given me an update when labs come back (typically through a message in the online portal), even if they're all good, and the labs are quickly uploaded onto the online portal so I can see it. Sunshine vet has an online portal that they seem to not use. After waiting 2 weeks after getting my dogs labs done, I hadn't heard from the doctor so I had to call and ask for the results. Additionally, the doctors notes were not uploaded or given to me, so I called for that a few months after the visit and although it had been months, they did not have the notes on hand. I ended up having to ask again a few days later before they sent them to me. That also does not give me confidence in them since they don't have their patient's records readily available. Another huge drawback is that they charge a tech fee for shots. I space out my dogs shots so it's completely unreasonable for me to pay an additional $20(? can't remember the exact fee but it was somewhere around there) every time I take her in for a shot. Overall, a strange experience that did not make me feel comfortable. I expect good communication and documents to be accessible at the bare minimum.

Grand Animal Hospital was offering a $200 off Dental Cleaning Special. For Grade 1 or 2, the price would be $696.75. For Grade 3 or 4, the price would be $797.75. This price was very reasonable compared to other quotes I received. I made an appointment. The vet examined the dog and determined that it would cost $797.75. This price included an exam, bloodwork, anesthesia, teeth scaling and polishing, pain injection, antibiotic injection, and three different medications to take home. I left her there around 11 am and picked her up around 3 pm. As you can see by these pictures, they did an incredible job! The staff was so nice and answered my many questions. If your pet needs their teeth cleaned, I highly recommend Grand Animal Hospital!

She started to sneeze a lot yesterday and it looked like she was trying to get something out of it. Since our regular vet didn't have any appointments, I scheduled a same day visit at Grand Animal Hospital. The doctor (an Indian female, though she never introduced herself or gave her name) examined my dog very briefly which literally just a couple of seconds and said she wanted to order an X-ray and bloodwork to check her white blood cell count. I asked if she could check inside my dog's nose for a possible foreign object. She said she couldn't because it would require putting my dog under anesthesia. I then asked if an X-ray would show a foreign body, and she told me no, it would only show structural issues, which was not my main concern. However, shortly after, she contradicted herself and said the X-ray could show a foreign object. She also said the bloodwork would show inflammation, but my dog's nose was already visibly swollen inside and bleeding, so inflammation was obvious. When I tried to explain that the inside of her nose looked swollen, she interrupted me and said, "there is no swelling, everything looks normal," without even properly examining her. My dog is a Pomeranian with Alopecia X (hair loss), which is a very common condition in this breed. When the doctor saw my dog has no hair, she looked suprised. The doctor seemed unfamiliar with it and suggested my dog must be mixed, which is incorrect. I also mentioned that my dog has itchy skin on her sides, but the doctor ignored this concern and instead just said she didn't see any fleas, which makes no sense since my dog has almost no hair. At the end of the visit, she said a nurse would bring an estimate for the X-ray and bloodwork. When the estimate came out, there was an additional test for upper respiratory infection that the doctor had never mentioned. The total estimate was around $1100 for only x ray and 2 blood work. This is the most expensive hospital ever. Overall, I felt like the doctor did not listen to my concerns, did not perform a proper exam, and was more focused on ordering tests than addressing the actual issue. Because of this, my husband and I decided not to proceed with any of the recommended tests and left. Unfortunately, the visit still cost $59, which felt like a complete waste given the lack of care and knowledge. The nurse was nice and waiting time was quick.

I visited on January 30 for my cat Elliott to consult about dental issues and a possible tooth extraction, and unfortunately had a very disappointing experience with Dr. Choi. He arrived about 45 minutes late and did not initially apologize. We understood delays can happen and moved forward with discussing our cat's condition. However, when we asked about the risks of a tooth extraction, his response was, "Well, any cat can die here, we don't know," delivered with no empathy or reassurance. He then brushed off several of our questions and quickly asked if we had anything else, making the interaction feel rushed. Later, he mentioned our cat might have an eye condition. When we asked for clarification about what that meant, he told us, "You can Google it," which was shocking and unhelpful. We were considering proceeding with this clinic for a $1,000-$2,000 extraction, but this experience left us uncomfortable. I've never encountered a doctor who seemed so dismissive, lacking compassion and clear communication, especially during a short appointment that lasted only about 10 minutes. This veterinary clinic apparently used to be a privately owned clinic which is now corporate-run. Regardless, there is no place for doctors to lack the basic empathy and compassion to provide care to animals. This experience truly left me speechless. After visiting another doctor at another clinic who was truly compassionate and made our concerns feel heard, I decided to proceed with dental extractions there. I would advise not consulting or visiting this clinic!

When I think something is impossible, they show me it's doable. When my dog isn't cooperating and I think it's best to go home, they show me there's another option -- and that it will work out. They answer all my questions. They're honest with me. They don't try to rip me off. They make me smile and laugh even when I'm stressed. They're understanding, kind, and truly the best kind of people -- the kind who genuinely care for every animal they see, reactive or not. They set the standard for how animals should be treated and cared for.

We waited for at least 45 minutes to even be seen when we had an appointment, when it was finally our turn we had to "wait for a room to open up" At the end: when they finally brought my cats back out they brought one out soaked in his own urine because "he's growling and hissing" he has never growled or hissed at anyone before, no other vets, no friends, no strangers. TLDR: Horrible experience, just needed simple vaccines, took over 2 hours, tech doesn't listen or remember anything correctly. Made my cat pee and poop himself.

We are willing to pay double the visiting fee. She went in for about 5 minutes and then another gentleman came out and told us the same thing. The clinic was sold and we close at 11PM now, etc. I took out my phone and showed him that it's 10:27PM. He said they wouldn't have enough time to do procedures to our cat. I told him our cat is old and he can't handle that much pressure anymore going to Glendora.. Long story short, this place has last call like some high end restaurant and I'm guessing everyone wants to get off work right at 11PM. Good luck with the "new management last call clinic". Getting off work is their first priority and not saving pets lives!
