Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Great Doctor
She and her staff are incredibly patient, kind, and understanding! I have had the worst time getting my stomach to accept the solution I need to drink to have my colonoscopy. I’ve tried 2 methods and am on my 3rd try. I should be good with this tablets. I also had my Endoscopy done by Dr Tieng. She is very nice and made me feel comfortable before and after the procedure. She answered my questions explained what she did and gives a solution to your problem, or a game plan on what’s next. Thank you and your girls in your office for putting up with me and being so understanding.

I was dollowing up after being discharged from the hospital, due to a foot infection. When we were talking she asked if I had atarted my go c treat t ment . and I asvised he no that I didnt get a call for an appointment to the treatment cwnter that was. Close enough for me go go to and that I had requested she be the one to provide my treatment for hep c. And was told I w out is receive a letter on the decision when it was made in acouple of weeks. But s r ill havent received a letter or a call back on messages I had left. Beinf upset by all of rhis she contactes and completed my referral before I had even left her office . and being advised to call her offuce if the treatment center hadnt called me and made an appointment in 2 weeks. I received a call from her office again to see if an appointment had been,made. Then her staff called and I was called for aanappointmnet At the center the same day. THANKS DR TIENG and staff.

I have a complicated GI problem and have had to see doctors while traveling. As a result, I've interacted with numerous GI drs over time. Dr. Tieng was very impressive. I would highly recommend her based on her knowledge and bedside manner.
