She is by far the worse physician anyone can have!!! I have had a colonoscopy with her three weeks ago. After two days, I was in the Emergency Room, with kidney stone. During a Ct Scan, the doctors foud out that I have a cyst on my liver and other complications. I brought out to her attention and she didn't even want to know about it!! She just told me to follw up with a family doctor!! She is my gastroenterologist, for God sake!!

Dr. Ma was very professional and diagnosed my problem quickly through some testing and a procedure. She is very friendly and easy to talk with.

I went to Dr. Ma a few years ago, and will be returning to see her again next month. I was bowled over by her candor and compassion! She made me feel like she had all the time in the world for me. She is so thorough and I felt like I was in the best hands!

rushing out of office and seems to not care about my concerns.

Dr. Ma has been my gastroenterologist since 2008. She is professional, knowledgable and the best at what she does. Because of my family history, I've had to have regular colonoscopies - all performed by Dr. Ma. During a recent colonoscopy (as in previous years), Dr. Ma and her medical team (from her nurse to the anesthesiologist), were very professional, caring and guided me through every step. I have never had a bad experience there and would highly recommend her to anyone for excellent care.

Unprofessional, not nice, money hungry doctor. Scheduled me for a procedure without explaining plan and that it would cost me. Procedure was scheduled in December and due to me changed insurance companies, it filed it as if I didn't have insurance at all. Now I have a collection agency calling me requesting a mortgage rate payment for a procedure that took her less than 10 mins - greedy. Would never go there again or refer anyone to go to her. Disgusting!
