He earned his Master's degree from the University of Georgia in 2005 and continued his education until the completion of his PhD from UGA in 2010.
Rex joined UGA Athletics as a football strength and conditioning coach and team nutritionist in the fall of 2002.  He spent 10 seasons coaching and developing the football team that won SEC Eastern Division Championships in 2002, 2003, 2005, 2007 and 2011.  His teams also won the SEC Championship titles in 2002 and 2005.  During his coaching career, Georgia football teams won 10 or more games in 7 seasons and made bowl appearances in each year, winning the Sugar Bowl twice, in 2002 and 2007.  Rex also was the director of the strength and conditioning for the University of Georgia men's golf team that won the 2003 SEC title and the 2005 National Championship.  Rex also has NFL training experience as he trained former Georgia players for the NFL Combine each winter and would coach them when they would return for their off-season.
Rex resigned from coaching in 2012 to pursue a project in which he developed training and rehabilitation programs for the United States Army Special Forces.  He also developed programs for the Wounded Warriors Project.  Each program was designed with each individual soldier as the primary focus.  As Rex continued to work with great athletes and soldiers, he began to realize how they needed coaching and direction in another area of their life, that area being finances.

“I really like the office dynamics here,” she said. “It’s laid back and easy going. It definitely is a different atmosphere than the probation office.”
