Dr. O'Sullivan is very good at calming me down and bringing down my blood pressure. We talked for a while and down came the numbers. I look forward to seeing him. In the fall.

This was my initial visit with Dr. O’Sullivan and he was engaged, interested and prepared. He was so personable and professional. I was instantly at ease and felt confident with him. He created an instant rapport and was a good listener. His experience gave me a true assessment of my condition and one that was believable to me…all with care and without judgement. I felt cared for and relieved after meeting with him.
