About

At Extended Healthspans, Dr. Stephan Goupil delivers longevity and lifestyle medicine from his Westford, Massachusetts practice. He founded the practice in 2024 with a clear focus: helping patients prevent, manage, and reverse chronic disease through evidence-based interventions. Dr. Goupil brings dual credentials as a DO and a PhD in Biomedical Science with a specialization in the Biology of Aging. He holds board certifications in both Family Medicine and Lifestyle Medicine. His clinical approach centers on the six pillars of Lifestyle Medicine: nutrition, physical activity, sleep hygiene, stress management, social connection, and avoiding risky substances. He uses advanced diagnostics to uncover root causes rather than treating surface symptoms. Memberships start at $150 per month and include telehealth check-ins, portal access, lab review, and monthly community Walk with a Doc events. Extended Healthspans complements a patient's existing primary care relationship, focusing on long-term prevention and lifestyle change.
