Punctuality was on point. Clean facility. Welcoming, professional, and wonderful staff- made my endoscopy feel like nothing more than taking a nap. They went the extra mile to make me feel physically and mentally comfortable from start tofinish. Dr. Ton-That was professional and concise with his diagnosis. Very friendly and never seemed to lose interest in my case (even though it was a minuscule problem in my opinion). He made sure I got the proper exams done to determine the problem, whereas other doctors may diagnose you with a certain level of uncertainty and prescribe you medication essentially hoping it will cure your symptoms/ problem. After identifying the problem he took further steps to identify the cause so that I can avoid having a similar circumstance in the future. Will be going to him for any future GI problems and will definitely recommend him to any family or friend.

I had my first appointment today with Dr. Han. He got to me a few minutes early, was very polite and thorough, and scheduled me for a follow-up within a couple weeks. He went over prescription instructions with me as wellto make sure that I understood the next steps. This was a very positive experience and I wholeheartedly recommend Dr. Han Ton-That to others!

My biggest issue was with his staff - I had to go to another facility for another procedure, and they staff at the office and the endoscopy facility did not communicate well at all. I got a lot of conflicting informationregarding my appointment time, and they also tried to move my time without consulting me.

Zero follow-up. I spent hundreds of dollars on follow-up tests and he never called to discuss the results.

I was supposed to receive test results in 3-4 days. It is day 8 and I called the office and they first said they received my results that day and the doctor would get back to me the next day. Thenthey told me it was someone else's results and they don't know when the test results would come back. I asked if they proactively call Labcorp if the test results are this late and they were confused. I was told to "be more patient". When you have an illness with painful daily symptoms, you would hope the doctor's office would be on top of receiving results that would diagnose the illness. This was not so for this doctor.

I was early for my appointment and was seen on time. You can tell their is communication with doctor and receptionist so your needs are understood. The receptionist are very friendly and not awkward even about the subjects of GI. Thedoctor is very friendly, calm, thorough and particularly in my case understood the urgency in the matter and did not want to wait to get tested with a colonoscopy.
