THE best medical practice anywhere, ever. Dr. Sullivan is extremely knowledgeable, professional, compassionate and caring. He takes all the time necessary with each patient, yet there is never a long wait time .... no double or triple booking. He intentionally makes his offices quiet and calming, and he carefully has built up a staff that is also caring and knowledgeable and compassionate. Especially noteworthy for years is Jessica, and more recently Lisa. What a trio. This doctor has kept me alive and well, despite my many medical challenges for decades. I actually look forward to my appointments. I am grateful to be a patient here and predict that they will continue to win the Super Bowl of Medical Practices each and every year. Thank you. Thank you.
