SharpCare Coronado physician Dr. Roger Oen, MD earned his medical degree with honors from George Washington University in 2002 and completed his family medicine internship and residency at UC San Diego. Board certified in family practice since 2004, he operates from Suite 340B at 230 Prospect Place in the 92118 ZIP with hospital affiliations at Sharp Coronado Hospital and Sharp Memorial Hospital. His clinical focus areas include sleep apnea diagnosis and CPAP management, diabetes and its complications, osteoarthritis treatment, arthritis evaluation, cryosurgery for skin lesions, depression screening, and eating-disorder identification — conditions that frequently involve musculoskeletal rehabilitation at Coronado providers such as Embody Physical Therapy and Pelvic Health. Spanish-language consultations serve the island's bilingual population and military families from Naval Base Coronado. SharpCare Coronado's evening appointment availability and Saturday morning clinic hours accommodate working patients who cannot access Orange Avenue's weekday-only practices, and routine vision referrals route through island providers including Alvarado Eye Coronado. Highest-complexity cases involve concurrent management of obstructive sleep apnea with comorbid type 2 diabetes, integrating CPAP compliance monitoring, HbA1c titration, and weight-management protocols within a single longitudinal care plan.
