Dr. Han Ton-That is a kind and wonderful doctor. I took a chance and booked him on Zoc Doc because my stomach was in a lot of pain. I could fill out all of my forms on the Zoc Doc app and text them my insurance card before I went. So easy. They also text you the address, phone number, and appointments.
During my appointment, we talked about my symptoms, he felt my stomach, and then we talked about what's next. I needed an endoscopy and colonoscopy so he could truly see what was wrong. He even walked me through how to do the colonoscopy prep with a demo. I was really scared and called his office multiple times with questions. The receptionists are kind and answer your questions and if they can't, they get the doc to call you back. The way he talks is so relaxed and calm. He reminds me of a kind grandpa who tells you to not worry. Highly recommend this doc for GI issues. Worth the drive. His specialty is diarrhea which was lucky for me since that was my issue!
Only "bad thing" is that the office is a bit old school. The scale is old and they do paper forms for things but if it ain't broke, don't fix it!
PS. I've now had my procedures and they went great. He uses Woodburn Endoscopy Center.

The provider I usually use did not have a gastro appointment available until May. My symptoms were getting worse and I had to find someone. Glad he was available for me to see relatively soon.

Dr Han Ton-That is professional and has excellent bedside manor. I found him on Zocdoc two years ago and I’m glad I did. He is knowledgeable and patient. He has provided excellent care over the years and would highly recommend him to anyone seeking any gastro needs
November 3, 2020Sam W.Verified patient
Found Dr Ton-That via Zocdoc, read great reviews and took a chance as I needed an appt quickly.
From start to finish great experience. Checked into my appt, it was quick and easy.
Front receptionist was very nice and attentive. Dr Ton-That came in, listened to my medical issues that have been ongoing for yrs. He in turn asked me very detailed questions then explained some things especially for upcoming procedure. So far everything is streamlined and a great experience. I have a procedure scheduled in 2 weeks. Looking fwd to more appts with Dr. Ton-That and to feeling better.
I'm so thankful for this experience. Most Dr visits don't go this great from start to finish.

Dr. Han Ton-That is the best doctor I’ve ever had for anything. He explains everything in detail, and in a way the patient can understand clearly. He remembers everything without having to remind or correct him on my medical history. He figured out my issue and have been healthy for the past year since we started treatment. Would highly recommend!
More than 1 year agoDawn E.Verified patient
I didn't feel like I was listened to - the doctor blamed my issue on the fact that I had gained weight. When I tried to explain that I had the same diagnosis about 3 years prior, before I had gained any weight, and when I was a size 4, the doctor just kept blaming the condition on my weight. He was reluctant to prescribe any medication and told me to just lose 10 pounds. While I agreed I'd like to lose a bit of weight, it was upsetting to have my previous diagnosis ignored and just blamed for a bit of weight gain.
March 3, 2020Dianna O.Verified patient
Very nice doctor, willing to listen to my history and provide good feedbacks. Endoscopy done nicely and explained patiently. I feel much better now! Highly recommended.
December 27, 2019Zi S.Verified patient
Office staff were friendly. In my opinion, the doctor was very respectful but too hasty to order endoscopy and colonoscopy for my reflux and distention. I thought medication was called for before resorting to procedures.

Very nice doctor, didn’t feel rushed at all. Good communication and explanations during exam. Friendly staff and clean office. No wait time. Very good experience.

Dr. Ton-That and his staff were very kind and considerate! Even from initially walking in, I was greeted by a cheery woman who quickly got me checked in and into a room. The doctor's bedside manner is empathetic and thorough. He summarized what I said and repeated it back to be sure he covered everything, which was great for me because I had actually forgotten to mention something important (almost whoops!). I've been dealing with and managing stomach issues for almost two decades, so I've seen several gastro's over the years. Dr. Ton-That was the first gastro that I've met who didn't want to play the passive testing/treatment game with my recent stomach issues. He described different testing methods, and made sure that I didn't feel pressured into anything. I plan on making a follow up appointment with them in the future. Great experience!
More than 1 year agoEmma C.Verified patient
Super friendly and very knowledgeable, seemed very straight forward and honest about his thoughts and instructions. Very efficient but didn't feel rushed.
April 26, 2019Christina G.Verified patient
The doctor seemed knowledgeable but I found it alarming that he immediately referred me for a colonoscopy and endoscopy after just a 10 minute conversation and him lightly pressing on my stomach. Of course that may be required in some cases, but this is the first time I’ve visited a gastroenterologist, I have no family history of severe stomach issues, and my symptoms aren’t all that severe. I assumed he’d start with bloodwork and modifying my diet before jumping off the deep end into an invasive procedure. I ultimately decided not to pursue the procedure because I’m about to leave the area anyway and didn’t feel like he’d established trust with me. I modified my diet by myself and immediately saw benefits. Honestly I went in hoping for a consultation and some advice on next steps, not to jump straight into a procedure requiring sedation! I plan to see a different doctor in the future once my schedule is less intense.
