I know Dr John Coon has an office in Riverside by Parkview Community Hospital but I saw him at Rancho Specialty in Rancho Cucamonga. I was so impressed. Everyone was so nice. Dr Coon really explains everything and I love the way he always asks about my family and even remebered that my daughter had been sick at my last visit and asked about her. I feel very confident. I am trying to find a way to put a copy of an article I found on Dr Coon in M.D. Net a magazine I found at my PCP's office. The article really let's you know all about his experiened and what a great bariatric doctor Dr Coon is.
