Sam Coffman began his medical education in the military as a U.S. Special Forces Medic (aka Green Beret medic) in 1989.  At that same time, he became highly interested in herbalism as a way to provide health care in remote regions with a minimum of medical supplies, both for acute care and trauma as well as for chronic conditions.

This was the start of a long journey into the world of plant medicine for Sam, and after thousands of clinical hours as both a medic on teams and in military emergency rooms, as well as working with herbs throughout following decades, Sam’s primary goal has become the creation of an integrative medical model that embraces both vitalistic and mechanistic aspects of herbalism into a collaboration with allopathic (orthodox) models of diagnosis and treatment. 

Sam founded and runs a survival and herbalism school (The Human Path) offering classes throughout central Texas, as well as a non-profit organization (Herbal Medics) which are both focused on providing herbal and integrative health care education and treatment in remote and disaster areas around the world. 
In Texas, Sam also works with a local medical doctor (family practice M.D.), providing herbal consultation for her clients as needed.  He additionally runs a student clinic through his school and consults with personal clients as a clinical herbalist as much as time allows.

Aside from teaching herbalism (600+ hour curriculum) and survival skills at his school, Sam also teaches survival and austere medicine to doctors, nurses and other medical staff who are preparing to embark into disaster-relief areas around the world.
