Oncology Associates of San Diego operates a Coronado Island cancer care center at 230 Prospect Place inside the Sharp Outpatient Pavilion adjacent to Sharp Coronado Hospital, 92118. Founded nearly forty years ago by Fred Saleh, MD, MOASD is now led by president Charles Redfern, MD, who earned his medical degree from Johns Hopkins University School of Medicine in 1991, completed internal medicine residency at Johns Hopkins Hospital and a medical oncology fellowship at UCSF, and holds board certification through the American Board of Internal Medicine with a subspecialty in oncology, with psychosocial support for cancer patients coordinated through island counseling providers including CrownTown Counseling. The Coronado clinic houses physician offices, exam rooms, and an on-site infusion center under one roof, staffed by a team of ten board-certified medical oncologists across five San Diego County locations now operating under the OneOncology national platform since 2022. MOASD provides detection, diagnosis, treatment, and follow-up for a broad cancer spectrum including bladder, brain, kidney, lung, prostate, and testicular malignancies, with in-home post-treatment support for elderly oncology patients coordinated through Comfort Keepers Senior Home Care. The practice's main facility at Sharp Memorial campus houses twenty infusion chairs across 9,000 square feet, and interpretation services covering 240-plus languages ensure non-English-speaking patients on Coronado Island receive full treatment-plan comprehension.
