Hanny Chan, MD is a Chula Vista dermatologist practicing through Sharp Rees-Stealy Medical Group's Otay Ranch location on East Palomar Street, serving the Eastlake and Otay Ranch communities east of I-805. His dermatological scope includes Mohs micrographic surgery, tissue transfer, and skin lesion excision — procedures for periorbital and facial lesions that require coordination with ophthalmologic providers including Otay Ranch Eyeworks Optometry for pre-surgical visual field baseline documentation. He earned his medical degree from the University of Southern California School of Medicine and is board-certified in dermatology with more than 20 years of clinical experience. His position within the Sharp Rees-Stealy system links his prescribing directly to complementary wellness modalities including the anti-inflammatory acupuncture protocols at Urban Sage Acupuncture + Wellness for chronic dermatitis and psoriasis patients managing flare cycles. Subspecialty capabilities include full-thickness skin excision with complex layered closure, cryosurgical destruction of premalignant actinic keratoses, and shave biopsy with dermatopathological interpretation for melanocytic lesion assessment.
