Dr. Steve Clark, N.D. grew up in Natick, Massachusetts, a naturally curious and introverted kid who loved to explore how things worked. He later attended the University of New Hampshire, studying pre-veterinary medicine and working in several research settings, including bench research in cell function and biochemistry. While at UNH he volunteered as an EMT.
Early in his academic career, Dr. Clark pursued allopathic medical school, telling interviewers he wanted “to teach people how to be healthy and take care of themselves.” After years of interviews, he eventually learned that this wasn’t the conventional medical model—an insight that redirected the course of his life.
He went on to work in the cardiology research department at Brigham and Women’s Hospital, where he published and co-published research on atherosclerosis, cell signaling, and the molecular development of heart disease. At Brigham and Women's he volunteered in the Emergency Department as a patient-advocate liaison.
His shift toward naturopathic medicine began unexpectedly during a deep dive into culinary herbs. That curiosity led him to medicinal herbs—and then to the website for the National College of Naturopathic Medicine (now the National University of Natural Medicine). The school described an integrative medical approach combining modern diagnostics, pharmacology, and natural therapies. Intrigued, he flew across the country to learn more and ultimately enrolled.
Dr. Clark’s strong science background shaped his clinical focus: understanding and treating illness by investigating biochemistry, immunology, and underlying dysfunction through thoughtful lab evaluation, all while applying core naturopathic principles to remove obstacles to healing.
During this time, he also discovered he had chronic Lyme disease aggravating the root cause of a long-standing digestive condition. These experiences fueled his commitment to integrative gastroenterology and Lyme treatment—areas that remain central to his practice today.
One of his mentors once told him, “If you put it out there that you take complicated cases, you’ll always have a full clinic.” Dr. Clark took that advice to heart. He has since become known for helping people who have fallen through the cracks of traditional healthcare. He finds joy in teaching patients how their bodies work so they can feel empowered and engaged in their own healing process.
Dr. Clark believes digestive health is often overlooked in modern medicine and spends time helping patients understand their symptoms so they can improve digestion—and overall health. He is also an avid home cook and foodie, navigating a gluten-free, egg-free, and otherwise restricted diet. His passion for cooking helps him guide patients toward practical, delicious alternatives and creative recipe ideas.
Dr. Clark has been a member of the International Lyme and Associated Diseases Society (ILADS) since 2004 and has spent his entire career treating Lyme disease and related infections. He views Lyme as a combination of Borrelia, co-infections, and the unique physiology of each patient. When someone isn’t improving, he looks for the underlying factor that Lyme is aggravating—whether biochemical, immunological, or lifestyle-related—so true healing can begin. Having supported patients with chronic Lyme throughout his professional life, he was thrilled when the U.S. Department of Health and Human Services officially acknowledged Chronic Lyme Disease as real in 2025.
The Latin root of the word “doctor” means to teach, and Dr. Clark embraces that role fully. He believes that effective naturopathic care must include education, because it’s difficult to fix what you don’t understand. His approach focuses on uncovering why a symptom is happening rather than simply treating the symptom itself. By blending his love of science, cooking, teaching, problem-solving, and patient empowerment, he creates treatment experiences that are both informative and deeply supportive.
When Dr. Clark isn't in work mode he likes to cook for his family, trail bike, cross country ski, garden, paint with acrylics and fix broken things.
