Functional medicine is a powerful tool for diagnosing the root cause of chronic illness by addressing the whole person, not a set of isolated symptoms. A functional medicine consult with one of our functional medicine physicians may focus on:

  • preventive medicine and well-being optimization;
  • difficult-to-diagnose symptoms and conditions;
  • reversing age-related illness; or,
  • chronic illness management and treatment.

How is this approach different?

A functional medicine approach:

  • is highly personalized to the patient;
  • examines the patient’s history, physiology, genetic makeup, and lifestyle;
  • considers the mind, body, and spirit of the individual;
  • takes into account external factors such as physical and social environment;
  • employs integrative medicine, a therapeutic approach which combines the best of conventional medicine with complementary and alternative therapies for treatment; and,
  • conservatively prescribes pills and surgery when medically necessary.

“There are no words to convey the love and appreciation I have for this healing place. We drive four hours to be seen by the doctors and it is totally worth it! My daughter has a chronic health condition that has not been triggered since we started our PALM protocol. Life-changing for her!”


“My doctor and chiropractor have helped me get rid of my cane and keep me working without back or shoulder surgery. I feel reassured and love every visit I have with them and the PALM staff.”

VITA G., JULY 2023

“I am so incredibly happy I made the decision to join PALM Health! This is how healthcare should be: doctors who can spend time with patients, expanded services on site, and access to alternative treatments. My doctor is simply amazing and makes me feel seen and heard. I have completely gotten rid of my gut issues and am on my way to being a version of myself I haven’t seen in years.”


“This is what healthcare should look like. The medical team is highly skilled, but the best part is that they truly get to know you and it’s clear that they care. For the first time since my MS diagnosis, I feel like I’ve regained some control over my body and my future.”
