Meet Our Functional MD Led Team

Dr. Eric Potter, IFM Certified MD

Founder, Physician

Dr. Eric Potter graduated from Vanderbilt Medical School and then went on to specialize in internal medicine (adult) and pediatric care, spending significant time and effort in growing his medical understanding while caring for patients from all walks of life. In recent years, he devoted countless hours to obtaining the Institute for Functional Medicine Certification.  This certification places him within a small group of regional practitioners who have completed the entire program.  At Sanctuary you will find the best of the conventional medical field combined with the best of Functional Medicine.

Beyond the science, Dr. Potter has personally experienced healthcare crises from both sides of care–as a physician and as a family member to patients. Working within our broken healthcare system and taking his family members through that same system inspired him to look for new ways to deliver the quality of healthcare he envisioned.  Stepping out of the insurance-based model of medicine allows him to provide whole person care in longer visits.  Providing wholesale pricing on lab tests and supplements removes the profit motive for these services, allowing patients to trust his recommendations.  Practicing Functional Medicine allows him to treat root causes rather than superficial symptoms. He endeavors to be the patient’s trusted advocate with the goal of restoring a healthier more abundant life.

Besides serving as a physician, he is married to an amazing wife and has six beautiful children. Their family has been shaped by the providential occurrences in their lives, including the beauty of adoption.

Dr. Potter also enjoys running, reading, hiking, and spending time with his family.

“Whatever you do, work at it with all your heart, as working for the Lord and not man.” – Colossians 3:23

Jeremy Paluch

Certified Nurse Practitioner

Jeremy Paluch, APRN, FNP-C Received his Master of Science in Nursing from Vanderbilt University. Jeremy’s interest in Functional Medicine began with his sister’s unfortunate Diagnosis of metastatic melanoma in 2009. This began what became a never-ending journey of research using diet and exercise to maintain and restore health. This eventually led to a clinical exercise science degree from Central Michigan University to show people the power of an appropriate diet and exercise routine for preventative and rehabilitative purposes.

His past and continued researched opened his eyes to a whole new world of practicing medicine by finding the root cause. Once his eyes were opened, there was no closing them. This guided his next decision to become a Nurse Practitioner with his sights set on functional medicine in order to help people to the best of his ability. Jeremy feels his path has been unconventional but knows God has guided his decisions every step of the way. He believes that the path to wellness is not always an easy one, but finding the root cause of illness is a journey worth traveling for true health and true happiness.

In his free time Jeremy enjoys listening to educational podcasts, reading, playing piano, exercising, spending time with family, and traveling with his wife.

Tiffany Balin

Certified Nurse Practitioner

Tiffany Balin, APRN, NP-C received her Master of Science in Nursing from University of South Alabama. She has always had an interest in health and wellness which initially led her to her first bachelor’s degree in Exercise Sport Science from Wayne State University, then this led into her Bachelor of Science in Nursing from Belmont University. She is completing her Advanced Fellowship through the American Academy of Anti-Aging Medicine (A4M) in Anti-Aging, Metabolic and Functional Medicine and will sit for her national certification in the Fall of 2023.

From then on, she became very passionate about finding the root cause of illness and not just treating symptoms. She believes digging deeper into an individual’s health journey leads to true healing. Tiffany feels God led her to Sanctuary and feels very blessed to be apart of the team and the patients we serve.
