NAPLES - Key Persons


Dr. Diane J. Brzezinski

Dr. B says it was challenging but rewarding to learn how to build rapport with her patients and apply her med school studies to real world situations. Here her "patient-first" focus and conscientious work ethic quickly led to a teaching fellowship at Michigan State University in 1996. After completing her residency, Diane was certified by the American Board of Internal Medicine in 1999 and opened her practice in Naples, Florida the next year. In order to connect with patients outside the office, she has been active in the local community as a member of the medical advisory committee of Bosom Buddies (which supports breast cancer awareness).
