Dr. Sullivan is a credit to his profession. Both his late father and I think he is one of the finest physicians we’ve ever encountered.

I am very satisfied with my first office visit from the front desk assistant to the time that Dr .Sullivan came to the room and listened to me talking about my health history and redirecting the treatment for my high blood pressure. Thank you all.

Dr. Sullivan is a compassionate doctor who listens to your concerns, explains your diagnosis, and then recommends how to proceed (e.g. steps you need to take, further tests, referral to a specialist, etc.). He is “down to earth” and seems genuinely interested in a good outcome for you.
