I had my first appointment with Dr Gulinson last week. When he came into the treatment room, I was very nervous. Dr Gulinson immediately put me at ease and was very friendly and cordial.I appreciated his direct and very professional approach to diagnosing my problem. He informed me of his plan on how to get to the bottom of everything. Dr Gulinson was very reassuring and very confident, yet not cocky. I look forward to a lasting and successful relationship with Dr Gulinson.
