The goal is to keep patients as healthy as possible, keep patients out of the hospital, minimize costs as much as possible and continue to provide patients with the best care.
CIMC’s primary care physicians and family nurse practitioner provide the island community with a solid foundation of care. When specialty care is needed however, a trip to the mainland is not always necessary, thanks to the visiting specialist providers who regularly provide services at CIMC.
Visiting specialists regularly see patients at Catalina Island Medical Center, typically on Saturdays in the medical group office and are often also available for virtual appointments. Podiatry, Cardiology, Ophthalmology and Vascular Medicine are just some of the medical specialties available.
Appointments must be scheduled directly with each visiting specialist’s office.
