What our patients think of Dr. Thomas Roshek.

"Dr. Roshek is very personable. Non-judgmental. When you are so overweight for so long, you invent reasons not to do things and always think that someone else is judging you as a person that can't handle themselves. At the Nicholson Clinic, I always felt like everyone there was behind me and willing to help at any point. Best thing about Dr. Roshek is that he always seemed confident in what I was doing, which in turn gave me confidence to be successful."
