Adam Courchaine, DMS, PA-C


Adam is a highly educated healthcare professional who graduated from UMASS Amherst with honors in Exercise Science in 1995. He started his career as an Exercise Physiologist and later worked as a Pulmonary Technologist at Boston Children's Hospital. Adam continued his education at Massachusetts College of Pharmacy and Health Sciences (MCPHS), where he graduated with honors in Master of Physician Assistant Studies (MPAS) in 2006. In 2022, he earned a Doctorate of Medical Sciences (DMS) at Lincoln Memorial University.

Throughout his career, Adam has worked in various areas of healthcare, including Internal Medicine/Primary Care, Pediatrics, Geriatrics, and Urgent Care. He also joined the Army National Guard in 2012 as a PA, now serving as an Aeromedical PA with an Aviation Battalion. Adam was deployed to the Middle East in 2017 and Kosovo in 2020.

Adam has witnessed the healthcare system in the U.S. becoming increasingly inefficient and less patient-centered over the past 30 years. In response, he founded NuMed Direct Primary Care in 2018, a healthcare model that focuses on health and wellness rather than sickness. This approach has been very successful, but Adam wanted to expand his impact and help people regardless of location. This led to the creation of his Feed the Beast program, which emphasizes ancestral living and optimal health and wellness.

In his free time, Adam enjoys outdoor activities with his family and their three dogs, including hiking, functional exercise programs, and rucking.
