South Orange County, circa 1969: On a barren hillside on the O'Neill Ranch, a group of proactive, concerned physicians envision the future. They know the rolling hills and wide-open spaces around them will soon be one of the fastest-growing communities in Southern California. They realize the need for accessible, quality medical care to serve the coming population. And they recognize the opportunity to practice medicine as they feel it should be practiced - a hospital built by doctors for doctors, allowing them to do the best job they know how to do.
