    ROOT CAUSE PSYCHIATRY

    We want to help you feel better.

    Have you ever felt like you must put on a brave face for the world, when inside you are suffering deeply? We want you to know: it’s okay to not feel okay. We will listen to your concerns, never dismiss them, and work hard to understand and resolve them. Whether you or your family member have been in emotional pain for days, weeks, or years, our caring team is dedicated to helping you feel better, for good.

    Using cutting-edge techniques to heal your deepest pain...

    Your mental health is not “all in your head”... far from it. In fact, a symphony of interconnected elements—your genes, gut health, immune system, environment, and even childhood experiences—come together to create and re-create a sense of emotional health or illness.

    At Potomac Psychiatry, we utilize cutting-edge diagnostic tools to fine-tune each of these elements to help you recover your health.
    Genetic Testing

    Your genome impacts your mental health. Thanks to advanced genetic testing, we can map out new possibilities.

    Nutritional Psychiatry

    The body and mind are intimately related. Our experts make the most of this connection to restore your hope.

    Medication Management

    We use precision medicine to avoid a trial-and-error approach to medication and select the best choice for your condition.

    "My psychiatrist has always been very quick to respond no matter what I have needed from him or if I’ve needed to speak to him outside a scheduled appointment. The office staff is always extremely helpful and kind. Very organized and well run. Best practice I’ve ever been a part of! Would give a 10 star review if I could."

    Christine M.

    "I have only had positive experiences at Potomac Psychiatry. The staff is friendly and helpful and my psychiatrist is amazing. They are quick to respond when I have a question or concern. I feel like I'm finally getting the help I've been needing."

    Tiffany E.

    "I’ve been with this practice now for about 5-1/2 years and I must say... my doctor I see has gone well above and beyond to help whenever I’ve been in a bind. Thanks to you all at Potomac Psychiatry!" 

    Christopher R.

    "Rather than simply prescribe pills, Dr. Kehr figures out what the underlying cause of a patient’s symptoms are. He gets down to the molecular level, patiently explaining things in a very understandable way. He’s a true scientist and craftsman with a superb manner. If you have had trouble addressing your issues and need a fresh and creative perspective, Dr. Kehr is your man. I cannot recommend him highly enough."

    Mark M.

    "The Root Cause program helped me to maintain the confidence that relief was coming in the near future. It was very assuring to know that doctors were going to solve my issues, not just partially settle them. Thank you to the entire Root Cause team for helping me to identify the source of my distress and getting me to a healthier state.”
