In many medical specialties, physicians receive time-limited certification by specialty boards and must undergo recertification (usually every 10 years). Diplomates (board-certified surgeons) of the American Board of Cosmetic Surgery receive ten-year terms of certification. Dr. Langdon was originally certified by the cosmetic surgery board in 2004 and successfully maintained his certification in 2014. He passed a comprehensive written examination, which was administered in Dallas, Texas in October 2014. In addition to cosmetic surgery, Dr. Langdon is also board-certified in dermatology (American Board of Dermatology) and in facial cosmetic surgery (American Board of Facial Cosmetic Surgery).
