At the Sharp Rees-Stealy Otay Ranch campus in Chula Vista, family medicine physician Ernesto Mendoza, MD, provides primary care on East Palomar Street in the Eastlake corridor near Otay Ranch Town Center. His practice operates within the Sharp Chula Vista Medical Center health system, giving patients on-network access to more than 33 medical specialties and 69 physicians housed at the Otay Ranch multispecialty complex. A graduate of the University of Kansas School of Medicine with clinical training in family medicine, Dr. Mendoza manages chronic-disease panels that include hypertension, Type 2 diabetes, hyperlipidemia, and obstructive sleep apnea. After-hours and weekend acute-care needs are triaged through the Sharp Rees-Stealy network, with overflow routed to facilities such as Perlman Clinic Chula Vista for conditions requiring same-day evaluation. The most complex panels involve multi-drug regimen reconciliation for geriatric patients carrying five or more concurrent prescriptions across antihypertensive, anticoagulant, and glucose-lowering drug classes requiring quarterly A1C and INR monitoring.
