Dr. Sun practices medical, surgical, and cosmetic dermatology and has extensive advanced training and experience in Mohs surgery and cosmetic facial reconstruction.

The Mohs surgery technique, when used in the appropriate clinical setting, offers the best cure rate and cosmetic outcome for the treatment of many skin cancers. This procedure requires Dr.Sun to first surgically remove your skin cancer. Then, while you wait, she will check under the microscope to ensure that the margins are completely negative and all of the cancer cells have been removed. Once this is confirmed, she uses her advanced cosmetic and surgical training to repair the defect utilizing meticulous precision and artistry in an effort to minimize scarring.

Dr. Sun is double board-certified by the American Board of Dermatology in dermatology and micrographic dermatologic surgery. As a fellowship-trained Mohs surgeon, she is an active member of the American College of Mohs Surgery.
