The American Society for Mohs Surgery (ASMS) was founded in 1990 by a small group of dermatologists in Southern California, all of whom had received extensive Mohs training in Residency and had successfully integrated the Mohs technique into their practices. The ASMS was envisioned as a professional medical society that would provide important professional and educational support for skin cancer training and the increasing number of Residency-trained Mohs surgeons throughout the country. The ASMS, however, welcomed members from both Mohs Fellowship training and Residency training backgrounds and created an environment in which members could openly share their Mohs knowledge and experience with other dermatologists.
