Doctor is ok, but his bedside manner is horrible. Not a good communicator. Seems competent, but clearly forgets he's in the client service business. Would suggest another doctor.

A colonoscopy.. can be a procedure no one likes.... nor do I; however, I've been seeing this doctor for years =stress free. He's professional, makes the procedure a breeze, is thorough and spends time with his patients. I highly recommend him
