My experience is always good, but like most of the time I forget to mention something that is on my mind everything I drink something or eat I choke. Especially when I drink water which is daily.

Dr. Sullivan is an excellent doctor. He explains information so that the patient can understand and takes the time to answer all your questions. You do not feel rushed. He gives a very thorough examination. The staff is also very nice, friendly and knowledgeable. There is never a problem scheduling an appointment to see him. We are very happy to have him as our cardiologist.
