Pedram Ghasri, MD, FAAD, dermatologist at Castle Dermatology Institute in Tarzana

For Dr. Pedram Ghasri, dermatology brings together his interests in medical science, procedural care, and the long-term health of his patients. A native of the Encino and Tarzana area, he returned to serve the community where he grew up.

Dr. Ghasri graduated summa cum laude from UCLA with a Bachelor of Science in Neuroscience. He attended UC Irvine School of Medicine as a Regents Scholar, receiving numerous academic honors and election to Alpha Omega Alpha, the national medical honor society.

During medical school, he spent an additional year conducting laboratory research on epidermolysis bullosa, a rare genetic skin disease. That experience contributed to his foundation in dermatologic research and complex skin conditions.

After completing an Internal Medicine internship at Huntington Memorial Hospital, he returned to UC Irvine for his dermatology residency, serving as Chief Resident during his final year. He also received a preceptorship sponsored by the American Society for Dermatologic Surgery, which allowed him to pursue additional training in New York City in Mohs surgery and reconstruction, cosmetic dermatology, and laser procedures.

His clinical work includes skin cancer detection and treatment, Mohs micrographic surgery, and the management of conditions such as acne, eczema, psoriasis, rosacea, hair loss, vitiligo, and other dermatologic disorders. He also performs cosmetic procedures, including injectable treatments, laser procedures, chemical peels, and sclerotherapy.

Dr. Ghasri has published research in leading dermatology journals, including the Journal of the American Academy of Dermatology, Journal of Drugs in Dermatology, and Dermatologic Surgery.
