Science-Backed, Whole-Person Care for You and Your Family
Living in Williamson County offers a vibrant lifestyle, but struggling with a complex, mysterious health issue can make it difficult to enjoy everyday life. If you have been searching for a holistic doctor in Franklin who provides deep diagnostic answers rather than temporary symptom relief, Sanctuary Functional Medicine offers a compassionate medical home.
Directed by Vanderbilt-trained physician Dr. Eric Potter, MD (IFMCP), our practice is located right here in Franklin, TN. We blend board-certified clinical expertise with advanced functional medicine principles to solve the root causes of chronic illness in both adults and children.

Our Franklin practice focuses on conditions that often fall through the cracks of conventional healthcare. By looking at how genetic predispositions, environmental exposures, and lifestyle factors interact, we help patients overcome complex health barriers.

Middle Tennessee’s lush flora and humid climate contribute to high levels of mold and vector-borne exposures. Mold toxicity and chronic Lyme disease can disrupt every major body system, causing severe fatigue, dysautonomia, brain fog, joint pain, and chemical sensitivities. Dr. Potter has undergone extensive advanced training in environmental illness to help Williamson County residents safely detoxify and repair cellular damage.
(PANS, PANDAS & Autism). When a child suddenly exhibits severe anxiety, OCD, emotional outbursts, or tics following an infection, brain inflammation (neuroinflammation) is often the root cause. As a physician double board-certified in Pediatrics and Internal Medicine, Dr. Potter provides compassionate, expert protocols for PANS and PANDAS. We also support children with Autism Spectrum Disorder and ADHD by addressing underlying gut dysbiosis, methylation defects, and immune triggers.

Conditions like Hashimoto’s thyroiditis, rheumatoid arthritis, lupus, and Mast Cell Activation Syndrome (MCAS) occur when the body’s protective mechanisms turn destructive. Rather than relying solely on lifelong immunosuppressive medications, we investigate gut barrier integrity, chronic low-grade infections, and environmental stressors to help calm systemic inflammation.
Health is more than just the absence of severe disease. Our Direct Primary Care (DPC) program provides Franklin individuals and families with a relationship-based, natural-first primary care model that emphasizes preventative wellness, extended appointments, and direct doctor communication without insurance interference.
We offer tailored medical programs designed around the severity and nature of your health goals:
| Care Model | Best Suited For | Key Features |
|---|---|---|
| The Intensive Program | Designed for complex, chronic illness in adults & children. | 12-month structured partnership, in-depth diagnostic testing, dedicated care coordination. |
| Direct Primary Care (DPC) | Ideal for ongoing family care & wellness management. | Low monthly membership fee, extended unhurried visits, wholesale pricing on labs. |
Restoring your health is a collaborative process built on trust, precision, and thorough communication.
We begin by examining your life story, past health milestones, environmental exposures, and emotional stressors.
Using advanced specialty laboratories, we analyze mycotoxins, heavy metals, nutrient status, organic acids, and microbiome diversity.
Dr. Potter crafts an individualized care plan utilizing targeted natural supplements, dietary modifications, lifestyle protocols, and prescription medications when necessary.
As your body begins to respond, we adjust your protocol to ensure steady, long-term improvement toward vibrant health.

Dr. Eric Potter is a double board-certified physician in Internal Medicine and Pediatrics and an Institute for Functional Medicine Certified Practitioner (IFMCP). He earned his medical degree from prestigious Vanderbilt University School of Medicine before serving in conventional clinical settings.
Recognizing the limitations of insurance-driven, short-duration medical appointments, Dr. Potter established Sanctuary Functional Medicine in Franklin to deliver unhurried, whole-person care. He has completed hundreds of hours of advanced coursework in environmental toxicity, nutrigenomics, and pediatric neuroinflammation, making him one of Middle Tennessee’s premier experts in complex functional medicine.
