Dr. Barry Schumer has reduced his primary care practice size from 1,800 patients to 400. Like other doctors, the reason for this dramatic change is simple: He joined MDVIP, a personalized healthcare network of more than 800 doctors across the United States. The difference, he says, is extraordinary. "In my mind, I'd have a dozen or so patients that I needed to see in the next 2 to 3 hours, so I was always keeping an eye on my watch, making sure I wasn't running over," Schumer explains. "Face to face time with the patient was probably 10 minutes or less, and now I've got 30 minutes set aside for each office visit."
