Ehatsham Ahmad, MD, provides family medicine through the SharpCare Eastlake clinic at 2437 Fenton Street in Chula Vista's 91914 zip code, within the Eastlake Business Center north of Otay Ranch Town Center. The practice's longitudinal care model manages patients from pediatric wellness checks through geriatric chronic-disease monitoring, generating home-health referrals for mobility-limited seniors through agencies including ComForCare Home Care serving the South Bay corridor. A UC San Diego School of Medicine graduate, Ahmad completed dual residencies at UC San Diego Medical Center and Adventist Health White Memorial before joining the Sharp Community Medical Group system in 2022. The SharpCare Eastlake office operates within the Sharp electronic health record network, enabling real-time coordination with Sharp Chula Vista Medical Center for inpatient admissions and specialist consultations across the system. Routine preventive-care panels require fasting blood draws and urinalysis processing, lab work that Ahmad's patients can complete at rapid-turnaround facilities including Fastest Labs of Chula Vista for occupational health and toxicology panels. Highest-complexity primary care encompasses multi-drug diabetes management with basal-bolus insulin regimens, pediatric asthma action-plan development using NAEPP EPR-3 guidelines, and cardiovascular risk stratification through ACC/AHA pooled cohort equation scoring.
