Called to see if they had any appointments open and they didn't, I explained it was urgent and they said come in now. Dr. Sullivan and his staff are always very kind, compassionate and attentive. Dr Sullivan is an excellent doctor, he is my primary care physician, although I do have a minor heart issue that he makes sure gets screened for. His bedside manner is excellent, he is empathetic and pays attention acne always takes the time to listen to my worries. He quickly ascertains what my issue is and if he can't directly treat me, he will have his receptionist contact a doctor who can for me. I.am always satisfied with his treatment as a patient.
