About

She holds hospital privileges at Los Robles Hospital and Thousand Oaks Surgical Hospital. Her clinical focus spans internal medicine, geriatric care, women's health, and chronic disease management. Members receive same or next business day appointments, extended visits, a personalized annual health assessment, and 24/7 direct physician access for medical emergencies.
