I seem to be experiencing an irregular heartbeat and yesterday I received an echo and a 24 hour halter heart monitor. Next week I will be given a stress test. I feel like I'm in good hands for diagnosing my situation.

Always a pleasure to visit Dr Sullivan's office. The doctor and his staff are very attentive, friendly and professional. The girls ( Jessica, Nicole, and Kristal ) are the best! Friendly, funny, and caring. I was recommended by a friend and I'm glad he did.
