Ann Siefert, MD is a board-certified dermatologist practicing at Scripps Clinic Coronado, 1222 First Street, Suite 1, on Coronado Island — bringing 41 years of clinical experience since graduating from the Uniformed Services University in 1985. The practice provides full-scope medical dermatology on the same island corridor as Coronado Derm, with particular depth in skin cancer screening, actinic keratosis treatment, and acne management for patients across the 92118 ZIP. Siefert completed her dermatology residency at Naval Medical Center San Diego (1989–1992) and served as a Navy physician and flight surgeon before joining Scripps, a background that informs her treatment of sun-exposure and environmental skin damage common among Coronado's military and beach-adjacent population. Cosmetic dermatology patients coordinating aesthetic treatments alongside medical skin care find complementary services at Lilly Beauty Medical Spa on Orange Avenue. Procedures include excision and shaving of subcutaneous lesions, cryosurgery, Mohs micrographic surgery referral coordination, and tissue-transfer techniques for post-excision reconstruction on sun-damaged skin.
