Dr. Tieng welcomes
new patients and
DR. TIENG IS AN OUTSTANDING DOCTOR.
I’ve had procedures performed by her. She’s well studied, takes the time to listen to you, is thorough in her questioning and examination and her follow up is impeccable.I’ve seen some of the “best” GI specialists in the LA area and I’d rate Dr. Tieng higher because of her ability to carefully listen. She is also very professional and has a wonderful bedside manner. Bottom line, I’m very impressed.
DR. TIENG IS A WONDERFUL DOCTOR...
...with magic healing powers! She is very helpful and she solved my years long problem with just two prescriptions!
THE BEST DOCTOR I HAVE EVER BEEN TO... HONESTLY.
Very kind and caring. Very unusual for a doctor! If you are having gastro problems this is the doctor to go to.
DR. TIENG WAS VERY PATIENT DURING MY EXAM.
I was always embarrassed to go to a doctor for my intestinal ‘issues’ but the pain and discomfort were finally too much to ask for. I can now report I am pain free! Very happy with my decision and will be recommending Dr. Tieng to all of my friends.
I'VE BEEN UNDER DR. TIENG'S CARE NOW FOR 3 YEARS.
She removed several polyps during my colonoscopy and took the time to answer all my questions after I received my diagnosis. Dr. Tieng was calm and professional and I’m happy to report I now have a clean bill of health!
DR. TIENG HAS REALLY EARNED OUR TRUST.
I recommended my wife to her and Dr. Tieng made her feel very secure during her very first colonoscopy. She also takes her time during our appointments. And most importantly, my wife and I are finally comfortable going to see the doctor!
