Board Certification

The American Board of Dermatology’s mission is to assure safe, high-quality dermatologic care for the public by setting, promoting, and assuring standards of excellence for practitioners.  Certification by the Board is the public’s assurance that the certified individual has met those standards by not only graduating from medical school but also completing a rigorous accredited dermatology residency and passing the Board’s comprehensive examination.

About Physician Assistants

To become physician assistants, candidates must enroll in accredited advanced educational programs that include both didactic and clinical training. Before they can practice medicine, those who successfully complete their programs must secure physician assistant certification (PA-C) by passing a comprehensive exam testing their medical and surgical knowledge. When recruiting a physician assistant, our doctors consider only the strongest of candidates whose training included a focus on dermatology. Once onboard, physician assistants are guided through an intensive in-house training program, working side-by-side with the doctors until they demonstrate a readiness to meet HMG’s high standards for care.
