I have been going to Dr. Sullivan for well over 10 years now. He is to me the very best in a Dr. you could possibly ask for. He is a very smart Dr. and is very personable. I like him because he explains everything to you in terms you can understand and he really wants you to understand it. He is caring and when you explain your concerns he genuinely listens. He is like family to both my husband and myself. We come up from Florida every year for at least 7 years now to see him. He is extremely thorough with his patients and leaves nothing to chance. He is a fabulous Dr. I am so glad I found him all those years ago. He is one in a million! Let me mention his staff... they go out of their way I mean that. They squeeze me in plenty of times if I’m sick. They make copies or fax me copies. They r always pleasant and never get short with me if you know what I mean. I can at times drive these nice people nuts... I love all his office staff!!! Jess Nicole and Crystal! Tops in my book! Anyone that doesn’t go to this Dr. is truly missing out on the best care you can get from a Drs. Office!

Dr. Sullivan went over with me on all the tests that were done on me a couple of weeks ago. Also went over the blood test and went over test items that were out of range with me. He answered all questions also.
