While still serving in Iraq, Jackson was appointed a White House physician, serving on the staff of Air Force Brig. Gen. Richard Tubb. He was named the physician to the president in July 2013 and was retained when Donald Trump was elected president. That is an unusual step; typically, an incoming president selects a new physician to man the post.
In addition to Iraq, Jackson also has served in Norfolk, Virginia; Panama City, Florida; Pearl Harbor; and Sigonella, Italy.
Jackson has been awarded the Legion of Merit award and is a four-time winner of the Navy/Marine Corps Commendation Medal. He has earned three Navy/Marine Corps Achievement Medals and also was awarded the Defense Superior Service Medal.
Jackson married Jane E. Annable in Galveston on Jan. 30, 1993. They now live in Silver Spring, Maryland, and have three children: Libby, Ben and Matthew.
