Great dr very detailed on information answer all my questions. I was not worried at all.

Dr. Truong is the most caring GI physician! He helped my son while he was in the ER, and on a Sunday, he personally came in to make sure my son was taken care of. We are so grateful for his compassion, dedication, and kindness. Truly an exceptional doctor! read more

Dr David, is a great knowledgeable doctor, very friendly and he listened to his patients and their concerns very clearly. I recommend Dr David to family and friends and all I hear from them it's positive and they thanks me for that. read more

I strongly do not recommend Dr. David Truong's office. Our experience raises serious concerns about both patient care and professionalism. Dr. David Truong was my dad's doctor for years, and we finally reached a point where we couldn't continue. The way we were treated over time was honestly very upsetting. During appointments, he often seemed completely disengaged, sometimes even facing away from us, and it felt like he wasn't really listening to our concerns. What made it worse was how he delivered difficult medical news: very cold, with little to no explanation or guidance. Trying to get in touch with the office has also been a nightmare. Calls go unanswered, and messages aren't returned. Recently, I reached out multiple times to request my dad's medical records, which are urgent for his care. After going back and forth and constantly following up, they finally sent something, but it was just a few pages of lab results, not the actual doctor's notes or full records we asked for. This whole experience has been frustrating and honestly concerning, especially given how important proper communication and documentation are for a patient's health. I wouldn't recommend this office. read more

David Truong, MD - Michael, staff member - Gastroenterologist Near Me - Fountain Valley, California

Called multiple times and left 2 messages. Two weeks later and still no call. Got a new referral and have an appt w the new doc next week. If you can't hire a competent office staff, then how can I trust you with such an intimate part of my body. read more

This office needs to be reviewed by the medical board. There's no privacy to personal discussions in the office. There's no signage placed for other patients to respect a patient who is at the front desk having a conversation regarding appointments and details. I believe this is a violation of HIPAA. Some rules regarding cancellations are directed at some and not at others. The front desk is incredibly rude and disrespectful they are the gatekeeper and the first initial interactions with the office is negative. As someone who is not Asian I felt discriminated against and treated in a manner that was disrespectful and this takes a lot for me to say this I don't say this lightly. I know that Dr Truong is probably a very credible doctor but his front desk is his reputation and his first initial first impression which is incredibly negative. I suggest you fix the hierarchy attitude of the young girls in the front office and the gentleman who will rush you into a procedure appointment. I would highly suggest you put signage in your office so you're not fined by HIPAA but that might actually be too late at this point. Don't come this office if you need to make an appointment or rely on things to be done properly. A colonoscopy is not a joke it's a procedure and everything should go as planned and there should be no stress. read more

I was completely impressed with their professionalism and customer service. The staffs are really friendly and helpful. I highly recommend this business. This is my 2nd time using their services and it has always been great. Thank you!!! read more

Dr. David Troung is very wise and helpful. Rather than just prescribing medication he will recommend a book to learn more about how to reverse pre diabetes, he will give you short term goals to lose weight and control your sugar consumption. I highly recommend Dr. Troung. read more

I needed to schedule an appointment and have called multiple times, leaving three messages. It has been a month, and I still haven't received a response. read more

I just had colonoscopy procedure done with Dr. Trương. He is a very nice and caring doctor. He really spent time and listening to my concerns. The procedure was very quick and smooth that I did even felt it. I had been to other GI doctor, they don't really care and always rushed to finish so they can go to other patients. The staff from this office are also very nice and helpful. read more

This office is terrible!! Takes them a week to call you back from leaving a message!! I specifically told them I was moving and needed a colonoscopy asap and they had my paperwork approved for a facility that doesn't take my insurance then waited a week to call me back!! Waste of time!! Go somewhere else!! read more

I love this office. The Doctor had gone out of his way to make sure my granddaughter got her Humira medication. The staff is attentive and friendly and Vickie had gone out of her way to get her Humira prescription refilled. I 100% recommend this office. Very clean and organized as well. Thanks to all who helped is read more

I hate writing negative reviews but this one is justified and necessary. If I can rate him a negative 5 I would. Not only is he unprofessional, he lacks compassion. His office staff is no better. He's one of those doctors that thinks he's god and that patients should be grateful for his service. I can't even call him a doctor because he is not worthy of the title. My mom was very nervous about her first colonoscopy and the staff did not explain to her the procedure and was very short over the phone. She also experienced a lot of stomach pain after the colonoscopy and was concerned enough to call the office. The staff dismissed her concerns and lied that the doctor wasn't working that day (if he wasn't working than why is the office open to receive phone calls?) After 48 hours of pain, my mom finally received a call from him who was very annoyed she was taking up his precious time. I really wished I had read the reviews on here and other sites so my mom wouldn't have to suffer so much. We have since filed a complaint with the medical board for his unprofessionalism and negligence in treating patients. read more

Terrible office experience with lady named Tina very aggressive and rude, went for 3 appointments was worse every time I went. I treat her with respect she still treat people like trash. Went 3 appointments never get to be seen by dr troung. Why? It was only different ladies every time. I would not recommend anyone to go to this place. Hope they change office lady. No stars from me as I was in tears every time I left the office because of the same rude lady. read more

I have been seeing Dr. David Truong for the last nine years having stomach problems He explains thoroughly on a colonoscopy and endoscopy he is very patient and efficient no complications I was so happy he is precise on my stomach issues. I would recommend to my friends Dr. Truong His staff is amazing kind and friendly also very helpful. Would like to thank Tina and David for your help. read more

Worse doctor in OC. Never go to this doctor. He is rude and careless. He never follows up on patient after the surgery. He didn't explain clearly what you have to do. He always seems like he is in a rush. My Mom was really sick and she had to go to the hospital twice and we had to go to dr. Truong for an urgent EGD. After the surgery he didn't follow up on my Mom or explain to my Mom what she needs to do. I was so worried about her so I called the office to ask for my Mon's status, 2 days later he called me back and yelled at me because I kept calling the office. After he got the report for my Mom, he didn't care to call back. What is wrong with asking questions when you don't know what to do, when you are really sick and want some words from the doctor. Bác sĩ này rất tệ. Không có tâm và không có tôn trọng bệnh nhân. Bác sĩ khám rất lẹ và không lắng nghe hay giải thích tận tình. Bác sĩ còn la bệnh nhân nếu bệnh gọi lại hỏi thăm về bệnh tình. read more

My mom got great care and service from Dr. Truong and staff. He also has new technology to get rid of hemorrhoids during coloscopy procedure. Thanks so much Dr. Truong. read more

With a different doctor, I had a painful and arduous experience 16 years ago with my first colonoscopy where I found out I had a redundant colon. I now had to have another colonoscopy to verify test results. I shared this previous experience with Dr Truong who noted my condition and my fear of the procedure. He recommended monitored anesthesia which worked out very well. The colonoscopy procedure, as expected, was technically difficult, but I did not have any pain at all, and the procedure was safe and effective. He clearly explained the results and the report in a follow up visit. I feel confident in his expertise. read more

I have been a patient of Dr. Truong for the past 5 years and he is amazing! He always answers all my questions, provides useful suggestions and is a great support always. His staff is also amazing & so friendly every time I visit. I always feel so welcomed and it makes me more relaxed. Dr. Truong's office is a place I would suggest for any friends and family to visit since I know everyone will get the best treatment! I highly recommend visiting this office! read more

It was really hard to make an appointment with them. The nurse would make me wait while calling again and again then tell me they would call me later, which they didn't three times Terrible customer service. I even come as far as going in there to make an appointment but instead greet by a rude doctor with big eyes bag. Don't get me wrong the facilitate was nice and advance, but it doesn't feel like they care if a patient is there or not. That is a big turn off for being a doctor. read more

I came here due to my constant bloating , abdominal pain , and indigestion . Dr Truong is truly a life saver ! When I was going thru the worst pain of my life . He ordered an endoscopy , colonoscopy and multiple biopsy to make sure everything was well in my stomach. I always had fear for even going to a doctor but Dr. Truong and his staff ( ch thu) really made the whole process easier . Thanks to Dr . Truong for treating me correctly ! Highly recommend. read more

The Doctor was VERY kind and made sure that every concern was addressed. He didn't brush anything off unlike every other doctor known to mankind. I really recommened him. read more

Had a 9am appointment. Dr Truong did not show up to the clinic until 930am. The receptionist never said a thing why the wait as too long. Understand things happen & the doctor is late but at least keep patients informed. I was late for my next appointment & had to wait longer because I missed my scheduled time. read more

The wait for this doctor office is horrible. They gave me an appointment and when I showed up I still had to wait for along time (1 hr + easily) to be called in. So what is the point of the appointment? Will not come back and do not recommend to anyone due to long wait time even with appointment. read more

I've been bringing my mom to appointments here for around 2 years. Dr Truong is very knowledgeable and helpful. He responds very well to questions and concerns. He is always very detailed when describing the current situation and lets us know any upcoming concerns or signs we should be on the look out for. He keeps us aware and moving forward. Right from the very start when we came to this office, the environment was friendly, low stress, and everyone made us feel welcome. They knew me by name before I realized it, and I'm not even the patient. Most doctor's offices don't have an effect on you like this one, they make you want to come back! read more

I love the friendly staff and Dr. Truong. The office is modern and providing care that is on par with high end American clinic. You will not find typical "Vietnamese style" clinic here. Dr. Truong saved my dad from colon cancer. Now my dad adheres to more preventive care than ever before. read more

I had a colonoscopy in May 2021. This is the second time I had colonoscopy with Dr. Truong. Both times the process went smoothly. Dr. Truong is very experienced and knowledgeable. He is very patient and care about customers. He answered every of my question thoroughly. His staff (Tina and Blanca) is very professional and friendly too. I highly recommend Dr. Truong as a Gastroenterology Specialist. read more

Dr David performed an endoscopy and colonoscopy for my dad, the procedure went So well and completed successfully without my dad noticed of anything happened around him. Dr. David Truong is a very kind and caring physician. Great job doctor Truong, also you are having a very helpful staffs who help us many things before and after the procedure. Great team work! read more

I was referred to Dr. Truong by my primary doctor. At first I was a bit worried but once I was able to make this appt., it felt like this was the office for me.. For one, the office is in a professional building off Warner & accross from Mile Square park. Office is decorated professionally and has 2 medical assistants who were attentive when I was there. I dealt with both of these assistants but mainly dealt with Blanca. Blanca is a true professional. She conducts herself in a caring way. I was not happy to have to have a certain procedure but Blanca made me feel comfortable and gave me some basic information about my procedure. Once I left this office I knew what was supposed to happen. As for Dr. Truong, he did speak to me briefly about the procedure and had me watch a video on the procedure I was there for. Dr. Truong is a very easy going doctor. He has excellent bedside manner. Later I had a few questions and called this office and again spoke to Blanca. She was very helpful and sounded like she really cared about me. I ended up having this procedure at the Magnolia Clinic. Dr. Truong took good care of me. My procedure went very well. His staff was very warm & informative. At first I was nervous but the surgery center staff made me feel at ease. If you're waiting to make an appt. with Dr. Truong, wait no more. I recommend Dr. Truong and his office staff and surgery staff. read more

This is the worst physician I have ever encountered. This man has no compassion, no empathy, and NO PATIENCE. I have been suffering from severe symptoms of GERD and IBS for years. The first meeting he did not conduct an examination. He just kept his face in his computer and asked me a few short questions about my symptoms and recommended me to buy certain herbal supplements. I was scheduled for an endoscopy. In the mean time my symptoms got increasingly worse. So his office person scheduled another appointment. This time Dr. Truong asked me the same questions as in the first visit. I began to describe my symptoms, but he interrupted me. He asked me another question; if I had taken the herbal supplements he "prescribed". I tried to explain that I started them but stopped and my explanation why (severe side effects). Dr. Truong interrupted me again. I said, "Please allow me to fully answer your question". Dr. Truong responded that he has many patients and needed to "direct my answers". Feeling frustrated, I politely asked him to allow me to fully answer his questions. At this point he became quite angry. He said that I had a bad attitude, and maybe I "should see a psychiatrist." If Dr. Truong had reviewed my med list, he would have seen that indeed, I was under the care of a psychiatrist and were on anti-bipolar meds. I was shocked and appalled that any physician would tell his patient to see a psychiatrist! Particularly a patient who already is. IMO Dr. Truong has bias against people with mental conditions. Then again, perhaps he just discriminates against white folk. I wouldn't refer this angry discriminatory physician to my worst enemy. BTW, though he told me he had to direct my answers because he had so many patients, I was his last patient of the day. The waiting room was empty. perhaps he was simply in a hurry to end his work day. 5 o'clock. read more

The reception staff were very nice and professional, especially Thuy Ng.. It did take 15 mins past my appointment time before I was actually seen but once the doctor sat down with me he took the time to listen and then explain his diagnosis and possible treatments. Dr. Truong made me feel confident in his knowledge and expertise. His skill and professionalism made the procedure go smoothly. read more

After having reviewed the recommendation from my insurance, I elected Dr. Truong to perform my first ever colonoscopy procedure. After consulting with Dr. Truong, the office nurse, Thuy, reviewed my insurance and made recommendation on the clinics that I should use to minimize out of pocket expenses while receiving the best care. This was December, and I was about to travel for work. She told me to call the office after I returned from my travel. It skipped my mind so I never called the office until December 28th. Thuy went out of her way to assure that I got the procedure done on the next day which was Friday before the year-end. Dr. Truong punctually showed up at the clinic on that day, greeted me, and carefully looked over my vital signs before performing the procedure. A moment later, I woke up on the hospital bed and realized the procedure had been completed. It had been a good nap for me, and I felt no discomfort whatsoever. I recovered well later that evening and even went out for a family dinner. It was great experience for me. I am looking forward to seeing him again for my next colonoscopy work. Thank you Dr. Truong and his staff! read more

I had asked my daughter to translate this review since I don't speak English very well. I'm a patient of Dr Truong, and he helped me get my medicine comped through medical that cost a lot and he was very helpful and professional about the whole process. After taking the medicine, I went back to get tested and I'm all better and back to normal health again. Thank you so much for diagnosing me and helping me through this process, don't know how to thank you! Hopefully this review will help future patients when they're researching into doctors. read more
