My husband and I go to Dr Sullivan since he started in Hawthorne. He is a thorough doctor who cares about his patients. He takes the time to listen to your problems if you have any and helps in anyway he can. We highly recommend him as our cardiologist.

It was to the point of my visit. We discussed several things and the answers were to the point and addressed to my satisfaction. Doctor Sullivan was polite, kind and very professional. His nurse who performed my INR test was terrific.

Dr. Sullivan and staff were great as always. I already had a couple of appointments since last year and at every time he explains everything to me in a very clear manner after I express my health issues. I would highly recommend to anyone looking for a good specialist.
