Daniel Marnell, MD practices dermatology in Grantville at San Diego Dermatology & Cosmetic Surgery, 6367 Alvarado Court, Suite 107, San Diego, CA 92120. He earned his medical degree from Georgetown University School of Medicine in 1966 and is board certified in dermatology, bringing more than five decades of clinical experience to the practice. His scope of care covers medical dermatology including psoriasis management with oral systemics, biologics, and phototherapy, as well as eczema, acne, rosacea, and skin cancer diagnosis through biopsy and histopathological evaluation. Marnell is affiliated with East Campus Medical Center at UC San Diego Health in Grantville, providing a hospital-system connection for cases requiring surgical intervention beyond the outpatient setting. The cosmetic surgery side of the practice includes Mohs surgery for basal cell and squamous cell carcinomas, liposuction, microdermabrasion, and laser-based procedures for hair removal and vascular lesions. The Alvarado Court address places the practice on the Grantville medical corridor near Mission Gorge Road, within the 92120 ZIP and less than two miles from the I-8 and Fairmount Avenue interchange. Marnell speaks Arabic in addition to English, broadening language access for dermatology patients in a corridor serving ethnically diverse communities across College Area, Allied Gardens, and eastern San Diego. Skin-health patients in the Grantville corridor who pursue complementary aesthetic treatments sometimes coordinate care with Daoist Aesthetics in San Carlos, where traditional Chinese medicine approaches to skin rejuvenation operate alongside Western dermatologic care. The practice also includes Fred Shahan, MD on the clinical team, and the two dermatologists share a caseload spanning general medical dermatology and surgical oncology within the same suite.
