Dr. Jeffrey Lee started his Army career in the 82nd Airborne Division at Fort Bragg. He was later selected to attend the Special Forces Qualification Course and, upon completion,  graduated as a Special Forces (Green Beret) medic. He was assigned to 5th Special Forces Group and served as a medical sergeant until he was accepted into the physician training program at the Uniformed Services University of Health Science (USUHS).  After graduating with his MD degree he was assigned to various conventional and special operations units.
