John R. Johnston, MD

My Philosophy and Approach to Wellness...

You are unique and your medical needs and goals are personal. You deserve an individualized approach to address your current medical problems and reduce your future health risks. It is important that you have a physician who has the time to get to know you well and is accessible when you need him. I am passionate about getting to know my patients and carefully listening to your needs. I am thorough in my evaluation and enjoy educating you on your conditions, risks, and your options for improving them. My practice is focused on preventive medicine with advanced testing and therapeutics, both conventional and natural.
