Dr. Obayedur Khan speaks with Dick Maier at his practice, Concierge Medical of Naples, on 5100 U.S. 41 North in North Naples, Florida, on Friday, June 5, 2015. Dr. Khanâs concierge service separates itself from most practices by accepting a smaller amount of patients and allowing more time with each individual. He opened his personal practice in April but has been working in Naples for about 10 years. (Calvin Mattheis/Staff)
