Just want to say my dr. visit was great as usual! Dr. Sullivan is the best doctor ever. I know I’ve said this before but we travel all the way from Florida to see him every year. He is just that good. Very professional and knowledgeable. He looks into every possibility if there is a problem. He leaves no stone unturned. He is personable as an added benefit and has a great bedside manner. What else can I say. Anybody who doesn’t go to Dr. Sullivan is completely loosing out on top quality health care. Check out Dr. Sullivan you won’t be sorry! He’s just the best! And his office staff are just as good…they get right to it. They are genuinely concerned. They always try to help if you are sick and not feeling well…they go out of their way to squeeze you in. Hats off to Nicole, Jess and Crystal as well! So glad I found Dr. Sullivan!
