I almost went through the Checkout Lane, but thanks to Dr. Castleman working me in, and getting me checked out on a Saturday (and sending me to the hospital). I am still around to talk about it.

About COR Healthcare Medical Associates

Welcome to COR Healthcare Medical Associates

With convenient offices in Torrance, San Pedro, Redondo Beach, Manhattan Beach and El Segundo, California, COR Healthcare Medical Associates is the largest premier cardiology group in the Los Angeles South Bay area. The team provides a broad range of services and testing facilities and is affiliated with Providence Little Company of Mary Medical Center in Torrance and San Pedro, as well as Torrance Memorial Medical Center.

COR Healthcare Medical Associates bases its care on an integrative philosophy, meaning they treat all aspects of a patient’s health — mind, body, and spirit. “COR” is the Latin word for heart. The practice dates back to 1952 when Dr. Milford Wyman established what would ultimately become COR Healthcare Medical Associates.

Since then, COR Healthcare Medical Associates has grown on the premise that quality health care stems from a collaborative team of experienced physicians. The cardiologists at COR don’t simply share an office, they work together to treat their patients and improve their skills.

COR Healthcare Medical Associates offers the most advanced technology in cardiology. Not only do they have an anticoagulation clinic, but they also have their own cardiac ultrasound lab and noninvasive vascular lab. The team also offers comprehensive heart rhythm monitoring, stress exercise testing, cardiac nuclear stress testing, and bone density testing.

For all-inclusive care with a team of cardiologists who place their patients’ well-being above all else, call COR Healthcare Medical Associates today or schedule a visit online.
