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.

He is very caring and through. I have a taste auto immune disorder and he works well with my other specialists.
I think it's Natalie, his medical assistant. She is very through.

Dr. O’Sullivan is a very down to earth doctor. He sits and chats with you about your health in general and lifestyle. He’s open to questions about different medicines and/or additional tests that are available. I do appreciate that he doesn’t recommends tests just for the sake of tests. Many doctors take s shotgun approach whereas I believe his care is more targeted.
