Cartwright followed Roger Staubach as starting quarterback for the United States Naval Academy as a sophomore in 1965. He led the Midshipmen to some of their finest seasons including a 1967 season that including victories over Penn State, Syracuse, and Army. In the process, he broke 13 of Staubach's school records and set seven others of his own.^[2]

Cartwright spent one season in 1973 as an assistant coach at what is now called Liberty University under Lee Royer. But after Royer died in a plane crash, Cartwright was named the school's second ever head coach and he spent three seasons leading the Flames.^[3]

Cartwright founded Calvary Independent Baptist Church in the Philadelphia community of Morton, Pennsylvania, in 1977 shortly after graduating from Liberty Baptist Seminary.
