He is very caring and through. I have a taste auto immune disorder and he works well with my other specialists.

Dr. O’Sullivan is a very down to earth doctor. He sits and chats with you about your health in general and lifestyle. He’s open to questions about different medicines and/or additional tests that are available. I do appreciate that he doesn’t recommends tests just for the sake of tests. Many doctors take s shotgun approach whereas I believe his care is more targeted.

Dr. O’Sullivan takes the time to listen to me about something that is going on in my life. He offers a sympathetic ear. I appreciate that. I also appreciate that he explains my test results so that I can understand them better and understand how the results fit in with the health of my heart.
