I want to make what can be a stressful situation as comfortable as possible for my patients and their families. I endeavor to offer the best medical care for my patients - newborn babies to geriatric patients.

    John Gray, MD

    Family Medicine with Obstetrics

    I have lived in Washington all of my life, having been raised on the farm my great grandfather homesteaded north of Spokane in 1898. I strive to maintain the balance between love and work that Dr. Sigmund Freud noted were the central aspects of one’s life.

    Patient Care Philosophy:
    I believe in using four major aspects of being a healthy human being – your physical, intellectual, spiritual and emotional self – to help bring health and happiness into each of my patients’ lives. I believe family medicine perfectly balances the tools of modern medicine with the wisdom of the ages to help people achieve maximum wellness.
