I was referred to Dr. Nguyen for my recurring sinus issues by my primary care doctor. Based on the reviews here on Yelp, I was a little hesitant, but I kept my appointment. Fortunately, I didn't experience any issues with the front office, but at least I was braced for it. I was able to met Dr. Nguyen, and I thought he was great! Straight forward, listened to and answered all of my questions. I explained that I was told that my sinus polyps had returned, and I was afraid that I was going to have another surgery to remove them. He ordered CT and wanted me to schedule a follow up appointment. I got the CT and had my follow up, and he confirmed that I didn't any polyps at all and wouldn't require a surgery. He then recommended that I follow up with my allergist. Over all, I was extremely satisfied with Dr. Nguyen. read more

The medical staff is good, but the office and appointments are so unorganized and unreliable. Very unprofessional to clients. Appointments aren't kept on time, and scheduling is a mess. They do not return calls, voicemails, or emails--terrible communication. I feel bad for the Doctors. There is no follow-up; very inconsistent- scary thought. I feel the office staff just does not care about doing a good job. Never again; I'd rather go somewhere else. read more

Please don't go this place I spend over $4,000 because I have sinus issues and I went to this doctor because the right side of my nose was collapsed and I couldn't breathe. He performed surgery on me. I paid $2,000. Two months later, the problem persisted. He told me that he was going to charge me another $2,000 to put in implants like glass needles, but one broke and he went and said that it was normal, that it had to heal. I've been going to see him for 3 months and he didn't want to see me anymore, that it's normal, that I'm fine and my problem is worse. Each visit costs $50 and it was like 8 times. read more

Henry H Nguyen, MD - Ear Nose & Throat Near Me - Rancho Cucamonga, California

A few things about this office.... They do not return calls, voicemails, or emails. Terrible communication. I called this office about getting a referral outside of my Optum Branch they said yes of course. 3-6 months later when I made the impossible happen, they told me no. Way to get a patients hopes up by saying yeah look into it and the same very encouraging person at the beginning of the whole process tells you NO, even though the insurance company and Optum had approved it. I wouldn't recommend this office for the terrible communication and care. read more

I don't like leaving bad reviews but someone needs to read this! Three of my family members including myself had to go here end of 2024 for services. I don't know what kind of business they are running here but they billed out of network on 3 separate bills! The billing dept was rude and argued that they billed correctly when I had already confirmed with my insurance company and they did bill out of network. They do facial scanning without getting proper approval leaving you with hundreds of dollars to pay! Check your BILLS and advocate for yourself! I investigated and all the bills were adjusted with a zero balance after I got my insurance company involved! Train your people to bill correctly and stop trying to rip people off! read more

Best place ever! I went there for ballon surgery, the staff and doctor are awesome. They helped me with my problem.

First time visit to this dr. I must complement I met with the doctor today and not a PA . He is very knowledgeable and listened attentively. He made a thorough exam of my main complaint. I recommend Dr. Ngyuen and his great staff. Kind, clean friendly and professional! Thank you read more

Dr. Henry H Nguyen has been extremely involved with me having Thyroid Cancer and METS to several major organs. I had the pleasure to meet Dr. Nguyen in 2018. He performed the original thyroidectomy. Which is the complete removal of your thyroid. You're sentenced to a lifetime blood tests and hormone treatments. Trying to figure out what med and strength you need. His bedside manner isn't the best . Let's be honest he's not there to be your friend. He's straight forward and means business. His staff is wonderful. Making appointments is one in a sinch. His office is semi updated in the lobby but dude when you go in to get stitches removed from your body and you're strapped to the chair. A super old surgical chair. This is what nightmares stem from. You think to yourself "God, is it now my time?" He then get s closer and closer. You feel life is diminishing and blood is everywhere. That's how I felt when he put a bandaid on my neck. Great I surgeon, not the best communication but if you want that fun in THE torture chair. His address and number is above. (C awesome surgeon for cancer patients) read more

Terrible service. Office staff could find my appointment twice. I have appointment cards for two appointments. I drove from Victorville to Rancho Cucamonga ENT & Sinus Center. First appointment was with Dr Roy. The second appointment was with Dr.Nguyen. I saw dr Roy in May he ordered lab work which I did. When I went to see the doctor again I was told they never had me down.. so they gave me a second appointment this time with Nguyen I never saw. I had a card with date and time of appointment. A person name mc Kenna set the appointment. I called before I went they didn't have me down.. this a horrible unprofessional place I have experienced.. I recommend to check it out.. read more

Dr Nguyen is a fantastic doctor. Very educated with a good sense of humor. His office staff has improved, but not always friendly. They rarely answer the phone and you always need to leave a message. I gave 4 stars for the Dr., he's worth seeing. read more

disgusting service, the doctor said that all the studies and the subsequent operation would be done urgently, but later everything was delayed and he refused his words despite my serious condition. Don't use this doctor. read more

They over booked pt, no respect for time. I had to take my daughter from school to see a doctor because the in front office said " I am sorry mam this is the only time we do have". So so so rude. read more

This doctor accidentally and carelessly destroyed my life and my ability to have a single moment of peace. I went in with sinusitis and deviated septum. I told the doctor I was spending my life savings on him, which was true. My first warning sign was in the first visit to him when he looked into my sinus with a camera-endoscope. He was extremely rough with that thing, far rougher than any other ENT I ever dealt with prior to that, or after that. Unfortunately, I just figured the reason it hurt so much was the camera attachment. But no... it was his lack of skill in using it without hurting me. (I found that out later). I unfortunately went ahead with the surgeries needed. After surgery, my nose was worse. The doctor said it was still healing and to wait. So I waited a few weeks and it was even worse. I went back to Dr. Roy for a checkup, and $60 and 10 minutes later, left after he said "give it more time". This went on and on for months. Each time he charged me $60 even though HE CREATED the problem. And what was the problem he created? He dug out so much cartilage from my nose...that my nasal valve collapsed. Yet Dr. Roy never figured that out. He just shrugged and charged me $60 each time I visited him. Not once did he even mention valve collapse. I do believe he either delibarately did not want to deal with this, or he is such a bad doctor, that he doesn't even know what valve collapse is. He certainly should have suggested to me that this was my post surgical problem. Instead of shrugging and saying "give it more time" and charging me $60 each time. I lost my entire savings on this man. I spent well over $4,000 in copays and doctor visits all relating to his surgery on me... which made me worse! If you care about your health, do not visit Dr. Deborshi Roy. The constant charging me to see him after his own mistakes..... and the botched surgery.... means that he is NOT the best manager of a medical practice, and he is NOT the best surgeon. I imagine he's not the worst.... but every ENT I've seen after him is far, far better, with more knowledge and more skill. And none of the others nickel-and-dimed me to death for repeated visits to tell me to "give it more time". The other ENTs I saw after him narrowed down the problem and eventually sent me to a specialist in San Diego who had to perform both corrective and secondary surgeries.... to minimize the massive damage created by Doctor Roy. So... why do I not sue Dr. Roy? I probably should. But my time and life has been consumed fixing the damage he created. Or trying to fix it. Thank God for Obamacare which was made available after my original troubles with Dr. Roy. Because of Obamacare, I was able to see better doctors who were able to fix SOME of the problems Dr. Roy created. Because of Dr. Roy, I went through nearly 3 years of suffering that was totally unnecessary. DO NOT LET THIS MAN BE YOUR SURGEON. read more

Henry H Nguyen, MD - The doctor. - Ear Nose & Throat Near Me - Rancho Cucamonga, California

I have had problems with my sinus for many years, I was referred to Dr. Roy. From the first visit I was extremely impressed at his knowledge and exceptional bedside manners. He is clear in his communication. I scheduled surgery, the office staff was great with scheduling and everything that is associated with making sure I was informed as to what to do, make sure bring someone to drive you home, called in prescription to my pharmacist. Now I can breath and sleep well at night. Dr. Roy is an extremely professional doctor and he really care about his patience. My surgery cost me less than $290 dollars, when you think about all expenses a doctors office pays to keep the office running plus the amount of schooling your doctor goes through it is more than fair. Exception patient experience. read more

First time patient, so I've never met the doctor. Why? Because the incompetent staff had no record of my appointment. I booked this appointment 2 months' ago, as it was the first available. Never mind the ear and sinus pain I've been dealing with. Once I finally got ahold of their scheduling person on the phone, I was informed that they are closing their office and will only be providing telemedicine...I need an ENT to actually look in my ear, as the issue is beyond that of a primary care physician...what kind of commitment to patient health is this? Lazy and pathetic. read more

My Mom had a terrible experience. She has problems with hearing and found Dr Nguyen. It took two months to set up a evaluation for her hearing. He spent about 15 minutes taking about interpersonal aspects of her life and about 3 minutes with an actual physical evaluation. She has had hearing problems for a long time. He spent less than 5 min looking in her hear and then solved nothing. No opinion. Nothing! Scheduled another appointment for another 3 months out. Wasted of time. Just another reason to take advantage of the elderly and change the insurance twice. What a waste of time. This "Dr." only cares about the money. Highly discourage anyone from ever going to this money chasing Insurance manipulator. What a waste of time. Don't waste your time. He is manipulating the system. Unbelievable service and a waste of time. read more

I haven't even been to see this Doctor yet but I just got a long awaitied referral . It's Nov and they are booking for February ... unbelievable ! read more

The 1 star review is for the lack of customer service skill. Every single person walking through that door is paying for a service that they need. There should be a level of respect that they can learn from greeters at Walmart. You say can say hi and thank you without damaging your RBF. I would NOT recommend coming here since you have to deal with the office staff more than dealing with the doctor. The day of surgery (10 am) we get a call from the surgical center stating our insurance didn't cover the procedure. After calling the insurance we found out there was an error in the coverage. This was resolved so it was not Dr. Nguyen's office's fault. BUT what was their fault was their failure to verify the insurance coverage was all set to go. This was 2 hours before surgery. It was nerve wrecking to go under anesthesia and to have to dealt with paper work literally minutes before was unbelievable. Dr. Nguyen is a competent doctor. He did what he said he would do. I don't expect the warm and fuzzies from him but when your seat faces the entrance and your job is to face to patients coming in, learn some basic customer service skill please. read more

Friendly ENT physician and partner Audiologist. I lost hearing in my right ear and had dizziness and tinnitus. They suggested a corticosteroid after doing some diagnostic tests first. My hearing has come back somewhat and the tinnitus is improved. They also ordered and MRI just to rule out unusual lesions like an acoustic neuroma. The staff is friendly and efficient. The waiting room is clean. Thank you Dr. Nguyen !!! read more

Dr. Nguyen did an incredible job on my husbands deviated septum, no tubes, minimal pain and back to work after only one week. Thank you Dr Nguyen for your wonderful talent and incredible team who treated my husband beautifully. Great Dr, amazing staff and comes highly recommended. read more

Hi, My name is Tommy, and my special needs brother Tan needed to be seen by an ENT. We were very fortunate to have Dr. Nguyen, and his professional and very caring staff took care of us. Vanessa in particular was amazing. She helped my mom out like it was her own mom and brother. She was very detailed and knowledgeable with the care we needed. And most importantly, she followed up w/ us the next day to see how my brother Tan was doing. We appreciated this so much. It's rewarding to know that someone cares not just about their work, but about the patient's well being. Vanessa is an excellent example of this. You will have a bright future, indeed! Thanks again, Vanessa! You are truly an Angel to us all! Dr. Nguyen is very lucky to have you on board! Keep up the awesome job! I will highly recommend Dr. Nguyen's office as the place to go for ENT. read more

We all know something is wrong when sites as such are used for a platform to vent. As an individual in the medical field I appreciate good medicine. The office of Dr. Nguyen office although, a very busy ENT office, high volume of daily calls and patient load, his office has excellent patient care. Dr. Nguyen is one of the best ENT providers in the Inland Valley area. As a patient of Dr Nguyen I know in great confidence that I am in the best of care. Although with long wait times, understand that there is a lot going on behind the counter and the providers there spend time with each patient and are dedicated in completing a thorough visit. His office staff works hard to ensure that you are treated with A + customer service! I highly recommend this office for any ENT needs!

I saw Dr Roy at this office! Both doctors are great though! Very nice and caring staff. Very clean office. It looks busy when you walk in but it is actually very fast and efficient so it doesn't really take long. Dr. Roy helped with a burn that I got in my mouth from a hot potato. It was fast and easy. Told him what happen he looked at it and prescribed me some medication for pain and wash to keep it clean and help heal faster. Great office! Great people! read more

Dr. Deborah Roy, had a great team working with him. First he is a straight forward, professional that listens to the patients needs are. A+++ Thank you to Yalisha in the back office. She is very helpful and friendly. From taking my vitals to setting up appointments everything seemed to flow smoothly. Even when they fit me into their schedule after I showed up late. On point for sure. Thanks again. read more

Have had issues with sinus blockages for a while. Saw quite a few ENTs who recommended a surgical operation but I kept putting it off because I didn't want to go under the knife. A friend recommended Dr. Nguyen's Balloon Sinusplasty procedure and that worked like a charm! It was a simple outpatient treatment, I didn't have to take a week off work and it solved my long term sinus problems! Very experienced Doctor who was patient to explain the procedure to me. Thanks! read more

I had one of the best experience while getting my throat checked at ENT the staff was awesome and the Doctor found my problem and suggested I check my medications because everything else was fine. I did like the Doctor said and found that my medication Lisinopril side affects was coughing. My doctor changed my meds and everything was ok no more coughing and blowing my nose I will recommend ENT for any Ear Nose Throat problem to my Fri and family. The staff there makes you feel comfortable and are willing to help with your concerns. Thanks Vincent Bell. read more

I have found Dr Nguyen and his staff to be courteous, efficient and skillful. I had sinus surgery performed by Dr Nguyen in November 2017 and the results have been positive. Although the office was very very busy today, I was treated in a timely fashion. Dr Nguyen and his team have exceeded my high expectations! read more

Dr. Henry Nguyen was highly recommended to me by Dr. Lamling Li ... Li Plastic Surgery for Dr. N's ability to diagnose and treat a deviated septum. I called ENT & Sinus Center to set an appt with Dr. N. When I called, the lady answering the phone asked if I could be placed on hold. I agreed. I was on hold for a total of 25 minutes and then the call disconnected... at 20 minutes, while on hold I called the office from my landline. A message came on to leave a message so I did telling them they left me on hold through mu cell and I was calling on the landline... at 25 minutes the cell call terminated on it's own. About 30 minutes later I received a return call from "Pam"... she was extremely rude and unconcerned about my 25 min hold time. She curtly stated that they had 3 providers all busy with another 3 staff members and a student so they don"t have anyone to answer the phones. I told her, had the lady who asked me if I could hold... would have told me to call back later because the office was slammed and understaffed... I would have done so, but to leave me on jold for 25 minutes and having the call terminated... was not cool... her reply was, "what do you want me to say? Things happen so what do you want me to do?" We proceeded with our conversation a oit setting an appointment and wanted me to know the surgery could cost up to $25,000.00... I hadn't even had a consult yet! She then advised if I had an authorization from my primary, based on my insurance it would cost $30.00 co-pay. Pam had an extremely rude tone throughout the conversation. After I hung up, I thought ...well if this is how poorly they treat a new patient... how bad will it be to resolve any complaint after any treatment. So as much as I trust Dr. Li's referral, I will not be booking an appt with Dr. Henry Nguyen BECAUSE OF Pam's rude and I don't give a damn attitude. Even if they are sooo good and popular and in demand for Dr. Nguyen's services... Pam should have a more polite and caring attitude when returning a patient's phone call. This provider is not a good fit for me... I hope other patients get better customer service than what I received. read more

I must give a shoutout to Miss Vanessa for being so accommodating to my disabled brother when I brought him in to see Dr Roy this AM. Thank you so much for being so understanding and going beyond the call of duty. I appreciate you, and the staff tremendously. Dr Roy was amazing. He was very patient, efficient and professional. Miss Kelsey, thank you for your kindness and professionalism as well. The young lady that roomed us and took my brother's blood pressure,I forgot her name :-/, was very patient and professional as well. I have worked in the healthcare profession for more than 20years. I get the pressures of meeting all patient care needs all day long. Keep up the good work. THANK YOU!!!!! read more

I don't know where to started. They charged me a copay. After 3 visits I called me insurance and they told me I don't have a copay with specialist. After see him 3 time and paying a bill and copay ( remember I shouldn't be paying)every time I came. They wouldn't take me to the back until my balance was paid. He said I needed a ct scan done, He has the machine in office but wait I have to pay 250 to get that done. Next visit he sent me to get a MRI. The office never called me to set up a appointment to get the resolves. I stop by and asked for a appointment. I was told he was booked until the end of July. It May 11. After waiting a Month to get my resolves. He come in and apologize about not get a call. Then he starts tells me about him be short handed and losing employees. Then he looks at my mri and tell him he can't help me. That I need to go see one of his friends. It's been a week and I haven't Heard from anyone in that office. Do yourself a favor go some where else. read more

Would leave less then 1 star but can't. This office gives you a phone number of 909-466-8600 Or 8611 which automatically rings busy at all times of the day and they have no recording. I had to call my insurance company to ask for a different number in order to get an appointment. Well the first thing they'll do is schedule you according to your insurance so if you have HMO or other then a PPO good luck getting in. They scheduled my appointment 3 months later and then one week before my appointment they called to cancel it and basically said you can find another office since your authorization will be expired. They seem to not want to take any patients with insurance they feel they don't get paid enough for treatment. In that case don't sign up as a Provider and waste people's time!! read more

Incompetent Office Manager!! One star, because without Yelp won't allow a review to be submitted without it. My daughter had a 1:30pm appointment. We arrived at 1:15pm. By 2:45, WHY are we still sitting in the front office? So, I go to the front desk and ask what is taking so long, ESPECIALLY after 6 people whom came in after us have been called to the back? I was told it is the first of the month and it just takes longer to check insurance. I looked at the "lady" closely to see what is really wrong with her. Because that statement is BS. After, a 2 minute exchange, I asked to see the office manager. Out comes Maritza. I explained to her that we've been waiting over an hour and 10 minutes & her front desk person STILL HAS NOT confirmed our insurance, can't find CT diagnosis can't locate the referral authorization (I brought in and gave it to HER with my drivers license and 2 insurance cards). So , I don't know why she was looking for it. Anyways I asked Maritza to assist her employee to speed up this process. Maritza replied to me, that by me talking to her (the office mgr ) I was the reason ,Why they were slow. How ridiculous does that sound? It makes no sense....... 1:30 appointment 2:45 I've had it we leave. 3pm called Prime Care Inland Valley placed a grievance. 3:45pm grievance submitted with Blue Shield. 4:30pm grievance submitted with Anthem Blue Cross. Maritza you need customer service training and Office management courses. GET IT TOGETHER . You have lost 2 patients for Dr. NYUGEN. ******Complaint filed with the San Bernardino county department of public opinion. read more

The doctor's here are good, but you should avoid this place because the office staff always has a huge attitude. They overbook and on my first visit it took the lady entering my paperwork over an hour to put it in the system. They really need to act like they care about their patients. I know with most insurances like mine, this is unfortunately the only option. They are rude and unfriendly. read more

I've called constantly and it's always busy. Like the other reviewer said. Really weird.

The only reason I am giving this place two stars is simply because Dr. Nguyen is amazing and was extremely helpful. The front desk staff on the other hand is the worst I've ever had to deal with. They are extremely rude, they seem annoyed half the time and they get upset for asking them a simple question. The physicians should definitely evaluate the people they have running the front desk. They have no customer service skills. read more

Came in for a scheduled appointment and they didn't have me listed. They couldn't fit me in because they overbook. The lobby is full of people waiting for their appointments that was scheduled at the same time. The doctors here are about quantity not quality. "Let's heard them in and make them wait." read more

Terrible! First of all it took over 2 months to get in to see the Dr. I've had a plugged up ear for several months and having problems hearing. It wasn't wax. My primary Dr checked for that and even gave me antibiotics in case it was an infection. But no change. So once I got to my appointment with the ENT, I was asked to fill out the medical paperwork in which I noted that I had had Covid 3 months prior. When the girl at the front desk read that, she told me the dr won't see me unless I had proof I was negative. I reminded her it was 3 months prior and I also had received my 2 Covid vaccines. She said it didn't matter. Dr won't see me with out negative Covid report. I was so mad especially since I waited so long to get in. I left and called my primary Dr who had referred me to the specialist and explained what happened. They were very surprised and said they would call the ENT office to see what happened. I found out from my primary Dr that they were told I had said I was there to be seen for sinus issues... and that they require testing for that. I told my primary this was a lie!! I never said that. I had told them it was for my ear. Needless to say, I won't be returning to this specialist. Luckily, My Primary was able to get me authorization to another Specialist with whom I confirmed no prior Covid testing is needed to be seen. read more

I have had Sinus Headaches and pressure in my Ears for 20 Years. This place was a joke! For Starters, I had a 2pm appointment, got there at 1:15, filled out all my paperwork by 1:45. They took me to a room where I waited until 3;30 before I was seen by Dr Nguyen. When the Dr came in He looked at my ears and nose. He said, well.... you probably have something going on with the tubes in your ears, but I would live with it. Then he proceeds to tell me as far as your headaches I would recommend to just keep taking over the counter sinus pills! I did not have to waste an entire afternoon for that. It seemed to me they were overwhelmed with patients and basically just blew me off. Dont waste your time. read more

My mom was referred to Dr. Nguyen by her primary doctor. I have to say that Ent & Sinus Center is very a busy office and now I know why the doctors are amazing professional and very thorough. The staff is also great although they have a millions things going on with the phones ringing none stop and the amount of patients they see the ladies still took the time to assist me with my moms insurance issues. I am not very versed as far as insurances authorizations and so forth but the ladies at the front took the time to explain and educate me on the process. I really appreciate the assistances. read more

Doctor Roy did a surgery on my ear to close a hole I've had for 20 years. Although I am still healing, everything has been great since my very first appointment. He accommodated my work schedule with my time off to make to surgery convenient for me. He has been nothing but nice to me during all of my appointments even though I'm worse than a child when it comes to people examining the inside of my ear due to my previous bad experiences. The desk staff is nice and respectful. The only thing that sucks is getting through on the phone- but since you aren't neglected inside the office- I account that to appointments being more important than the phone. read more
