This doctor is very rude. I had a liver scan and I called about 2 weeks later for the results and he was so rude on the phone. He said, basically, this is not how we do this. So I got off the phone wondering if I should have asked the receptionist or maybe a janitor in the office how my results were. I don't understand why a person who seems to detest the human race would become a doctor. This guy is truly an embarrassment to the profession.

Unprofessional, incompetent, lacks clear understanding of personal and human communication. Nurses at PIH Downey do not like him or his lack of personality and rudeness. His office in Lynwood should be condemned, it’s disgusting!

Had my first and last experience with this doctor, he is abrupt, no empathy, he made feel like we were wasting his time. I will never recommend him and I never want to speak his name. His staff is nice but he sucks!!! He doesn’t even deserve the 1star I gave him, it really should be a minus 1 star!

I would not recommend this provider to another patient. This is my first and last appointment with a Gastroenterologist. Throughout the entire appointment I felt as if I was being faulted for taking up his time. The way I was spoken to was condescending and belittling. There was no empathy, humane/personal predisposition or respect. Frankly, I don't believe that having a doctoral degree gives one a carte blanche to talk down to people. The clinic administrative staff did not have customer comment cards, so I am posting my feedback here.
