Meet Mark & Michele

Two Physicians. One Mission.
Your Health Restored.

Dr. Mark and Dr. Michele Sherwood founded the Functional Medical Institute on a conviction that has never changed. Chronic disease is almost always driven by identifiable, addressable root causes, and the physician's job is to find them. Together they bring over five decades of combined clinical expertise spanning naturopathic medicine, osteopathy, hormone optimization, genetic testing, peptide therapy, and nutritional science. They have helped thousands of patients reverse conditions conventional medicine labelled as permanent.

They are not here to manage your disease.
They are here to end it.
