Unlocking Your Natural Healing Potential
“I’ve been helping my clients find their optimal wellness through developing a deeper understanding of their body’s natural and incredible ability to heal when in a fully functioning state. Throughout this program I aim to create a life balance that prioritizes your well-being and celebrates all aspects of your true self. It’s time to start nurturing your body and soul again.”
— Dr. Martin Hart
Root Cause Functional Medicine Physician
Dr. Martin Hart is the co-founder of Keystone Total Health and the creator of the Keystone Root Cause Analysis™. He is known for his methodical, systems-based approach to complex and chronic health conditions, with a particular focus on identifying underlying drivers rather than managing symptoms alone.
Dr. Hart works extensively with individuals facing inflammation, autoimmunity, chronic fatigue, gut dysfunction, mineral imbalances, and environmentally driven illness. His approach integrates advanced functional lab testing, detailed pattern recognition, and personalized care planning to help patients gain clarity and direction in their health journey.
​
He is especially passionate about supporting patients who feel stuck, unheard, or overwhelmed by conflicting information, and he prioritizes education so patients understand both their results and their next steps.
Autoimmune
In helping people with autoimmune disorders through functional medicine, advanced diagnostic tools and patient-centered protocols, Dr. Hart has helped countless individuals find relief from chronic autoimmune conditions, such as Hashimoto’s thyroiditis, rheumatoid arthritis, and lupus. His methodology uncovers the root causes of immune dysfunction to restore balance and vitality to his patients.
Brain Health and Neuroplasticity
Brain fog, poor memory, anxiety, depression, headaches, migraines, motor tics, neuro-inflammation, movement disorders, PANS/PANDAS, and spasms are all signs of imbalances within the brain. The insights gained from working with these issues daily in practice have helped a multitude of cases to regain their mind, their brain, and their life.
Complex Chronic Illness
Mysterious symptoms often come with a laundry list of diagnosis. That’s why you need more than a specialist for each part of the body, you need a master clinician who can integrate multiple streams of knowledge of how all the body systems work together in a single framework.
Lyme Disease
Much more than a simple infection, Lyme Disease creeps into every part of your being and makes it presence known in all aspects of your life. We’re here to help support men, women, and children with exceptional client-care regardless if you were born with it, suffering from it for 20 years, or taking a proactive approach after a recent diagnosis.
Mold and CIRS Related Illness
Mold illness affects every major organ system and creates inflammation that slows you down and holds you back. It can be devastating to learn that your home or environment is making you sick, but our approach can help you find balance with health, so you can find control over your life quickly.
“I cannot say enough good about Keystone Total Health in Columbia Tennessee! I am more than impressed! I am so grateful that my husband and I drove seven and a half hours to get there. Now that I've been there, I don't think there is a distance I wouldn't travel to see them. People come from all around the world and now I understand why. They have given me so much hope again!
Thank you Dr Hart and your whole team! You all are a gift from God!
You deserve far more than five stars! I love you all!”
