He graduated with honors and special recognition for service to the community from Tulane Medical School and did his residency in family practice at the University of Florida in Jacksonville. Carriere pursued an interest in the treatment of alcohol and drug addictions and became the Medical Director of one of the first accredited alcoholism treatment programs in Florida; subsequently, he led the effort to develop three freestanding addiction treatment hospitals in Florida. His early family business experience combined with a passion for family medicine gave him a rather unique perception of the healthcare industry. He began his practice in 1975, and has built a solo practice into a 45 provider, eight locations primary care group. Carriere also serves in a leadership role at the North East Florida Regional Health Organization.
