Dr. Colligan is a great doctor! He respects your time and yet doesn’t make you feel hurried. I’ve never had to wait more than 15 minutes. He’s very easy to talk to and is very thorough. I would highly recommend him

Reserving judgment until a follow-up visit is completed. He ordered three test to be completed and then we'll see what happens once the results are in. He did not speculate on the problem - which is probably for the best.

From the time Dr. Colligan came into the office I felt like he was annoyed that I had made an appointment and had shown up. I felt like I was just an interruption in his day. By the time I leftI was extremely upset and have since found another Dr. that I love.

I wish he'd explain more about a procedure he is recommending. What's involved? What are the risks? What might they encounter and what are the options? What happens after the procedure?

Luckily I got a passing grade and don't need to check in with him for some time, but he was very personable and professional. I have been to a few other specialists that may have been smart cookies, but they didn'thave the personality to go with it. Dr. Colligan hits all marks.

This was my initial office visit. My appointment was at ! p.m., and I arrived at 12:50. Although the support was very efficient, they were not at all friendly. I am used to being greeted with at least a smile. Iwas quite impressed with the very brief wait time prior to seeing the doctor. He was very professional, thorough and courteous. I was in at 1 p.m. and out by 2:15. The office was nice and clean and there is ample free parking, a huge plus for me.
