      About Us

      Welcome

      Root Causes Medicine is a functional and regenerative medicine practice devoted to discovering and reversing the underlying causes of chronic and complex illness. Put simply, we search for the answers to the question, “Why?”

      "Why am I so tired?”
      “Why do I have intractable pain?”
      “Why do I have to have surgery, again?”
      “Why is this medication not helping me and possibly hurting me?”

      …and many others.

      The good news is that there is always an answer, and there is always something that can be done.

      Our providers will explore all of the regenerative medicine therapies available in an attempt to relieve the symptoms, slow the progression, or reverse the disease process.

      To see if we can help you get your health back, please give us a little information about yourself by filling out the form below.
