The Arizona Medical Board licenses qualified allopathic physicians (MD’s). The Board is also responsible for investigating patient complaints against physicians and when appropriate, taking disciplinary action against their licenses. Unlike medical associations and societies, the main objective of the Arizona Medical Board is to protect the public. Regulatory boards exist for other licensed professionals as well, including osteopathic physicians, physician assistants, psychologists, cosmetologists, accountants and opticians. Like the Arizona Medical Board, these regulatory boards serve the same purpose to protect the public.
