In Chula Vista's northeast Eastlake area, Dr. John L. Perry Jr, MD, maintains a medical practice on Kuhn Drive in the 91914 corridor serving adult patients in the Rolling Hills Ranch community. The practice's location positions it within the broader Chula Vista medical infrastructure anchored by Scripps Mercy Hospital Chula Vista on Medical Center Drive, providing hospital-level backup for cases requiring inpatient escalation. Dr. Perry's clinical focus covers general medical evaluation, diagnostic assessment, and ongoing management of adult primary care conditions within eastern Chula Vista's residential corridor between Otay Lakes Road and Olympic Parkway. Acute medical needs arising outside standard scheduling are managed through the broader urgent-care network that includes facilities such as Marque Urgent Care for walk-in diagnostic triage and point-of-care testing. The practice's scope extends to comprehensive multi-system physical examinations including 12-lead electrocardiogram interpretation, pulmonary function screening via office-based spirometry, and metabolic panel analysis for patients managing concurrent cardiovascular and endocrine conditions.
