Mary M O'sullivan, MD

I saw Dr. Sullivan with the onset of chronic severe breathing difficulties. She was one of the most compassionate doctors I've ever seen, she asked a range of in-depth questions to fully understand the problem, she gave a thorough check-up, and followed through with the range of tests to narrow in on the culprits. So often, we see doctors and they try one thing, then the next, then the next, but her approach is holistic, and her follow-ups are thoughtful, patient, and again thorough. When I have had to wait (once) she was apologetic, even though the wait was not bad. She will also push for tests that insurance may be hesitant to provide, if she believes they are important for diagnosis and treatment, instead of hesitating. She also gave lifestyle suggestions which, when implemented, have improved my overall health and quality of life. Can't recommend enough. Thank you, Dr. Sullivan!

Mary O'Sullivan has a terrible manner. She has a terrible attitude, is very rude and does not listen to the patient. She is condescending and dismissive to the patient. Who ever heard of any doctor much less a pulmonologist that permits patients to smoke E cigarettes in the waiting area? She should be reported to the board of health for this plus her less than clean office. Also, you may not get an accurate diagnosis. Beware.
