Very nice and office staff was great
October 3, 2017Richard S.Verified patient
This was probably the worst experience I've had with a physician. He did not want to listen to anything I had to say, came to a quick and expensive resolution for an ambiguous situation (without any apparent analysis) and spoke over me throughout the appointment. The best thing I can say is that his staff (not him) were nice.

Experienced & very pleasant. Highly recommended.
December 22, 2015Billy L.Verified patient
Dr. Khan was two hours late for my appointment. He spent more time typing on his laptop than he did talking to me.
He was rude and dismissed my opinions. He talked over me and was generally unpleasant.
I do not recommend this doctor.
December 6, 2015Larry P.Verified patient
Dr. KHAN WAS VERY KNOWLEDGABLE AND EVEN BROUGHT SOMETHINGS UP NO OTHER DR FOR 30 YEARS HASMEVEN THOUGHT OF. I WAS AMAZED AND IMPRESSED.
November 26, 2015Carolyn R.Verified patient
He seemed fine at first, but blew off the facts I was telling him about an issue that had already been confirmed. I agreed to have blood work done, and before I walked out of the office one of the nurses (Kind Nurse) asked me if I had someone to pick me up after the procedure. I asked her if I needed someone and she said "Oh yeah.. They're going to put you under" She handed me some paper work that broke down the procedure for upper GI Endoscopy... for Gallstones.
