I find Dr Merin to be very professional and highly capable. He spent ample time discussing my complaints and he ordered comprehensive tests to determine the cause of my difficulty. I do not hesitate to give him my highest recommendation for both his capabilites and his "bedside" manner.

I have been seeing Dr. Merin for years. He is the only GI doctor that has ever taken the time to talk to me. Other GI's just keep setting up tests and I only got to speak to their assistants. Most of his staff are nice and Jean the scheduler is terrific. Be on time - He is never behind.
