Drexel University College of Medicine class of 1986 (Alpha Omega Alpha) and NYU dermatology residency 1993–1996 credential the procedural dermatology practice of Eric Gerstenfeld at 4060 Fourth Ave #415 in Hillcrest, with additional hospital privileges at Scripps Memorial La Jolla and the Jennifer Moreno VA Medical Center. Excision of skin cancers on the trunk and extremities and surgical treatment of cysts, lipomas, and benign tumors coordinate with broader surgical-specialty capacity at Pacific Coast Surgical Group for cases needing deeper reconstruction than an in-office procedure room supports. Core dermatology workload includes full-body skin cancer screening, actinic keratosis treatment with cryotherapy and topical 5-fluorouracil, biopsy of suspicious pigmented lesions, and medical management of psoriasis, rosacea, acne, and eczema. Before entering dermatology, Dr. Gerstenfeld served as a Lieutenant Commander and general care physician in the U.S. Navy with a final assignment at San Diego Naval Hospital, and practices under California medical license G70325. Walk-in rashes, suspected cellulitis, and skin infections first triaged at occupational and urgent-care clinics such as Concentra Urgent Care are frequently routed back to the practice for biopsy and dermatology-level workup when findings do not fit a simple infectious picture. The highest-complexity caseload covers biopsy-confirmed melanoma staging workups and coordination of Mohs micrographic surgery referrals for high-risk facial lesions.
