A Patient-First Approach

Dr. Zachariah believes that every patient deserves a treatment plan tailored to their unique needs. He takes the time to help patients fully understand their diagnosis and all available options, recognizing that surgery isn’t always the best solution. When surgery is needed, he focuses on minimally invasive techniques designed to reduce recovery time and improve outcomes.

Beyond the Operating Room

Outside of medicine, Dr. Zachariah enjoys an active lifestyle, spending his free time surfing, cycling, skiing, practicing yoga, and enjoying time with family and friends.

Dr. Zachariah serves as the Medical Director of Neurosurgical Oncology at Sharp Memorial Hospital and has privileges at Sharp Memorial, Sharp Grossmont, Scripps Mercy Hospital, and Scripps Mercy Hospital, Chula Vista.
