Dr. Marion Owen, MD, and Susan Castle, NP, practice Functional Medicine, a unique lifestyle medicine-based approach that’s been proven to help people achieve optimal health. Instead of writing a prescription to mask symptoms, treating only the diagnosis or disease, referring you to specialist after specialist, or offering a laundry list of possible explanations, we take the time to listen to your concerns and uncover what is actually preventing you from living your best life. It’s only then that we devise an individualized, personalized plan to restore, protect, and optimize your health.

At Whole Family Medicine, the lines of communication are always open and the conversation is ongoing. Member participation is not only encouraged – it’s a vital part of the Whole Family Medicine experience. Our members are encouraged to come in frequently to build on progress, catch gaps in health needs early, get questions answered and stay engaged in the progress to health.  At Whole Family Medicine you are empowered to make informed healthcare decisions throughout your life. Finally, real healthcare you control.
