Charlie Morgan

For the past year I have been working with Rockdale Youth Soccer Association coaching in their Academy and Select programs.  Before moving back to the Atlanta area in July 2017 I was working at Hancock Day School where I taught Pre-K-8th grade PE and coached the middle school soccer teams.

Prior to working at Hancock, I spent one year as the Director of Coaching for the Wilson Youth Soccer Association.  I developed a player pathway curriculum that showed what each player should be learning at the various age groups.   I also created a coaching manual for all Select coaches to follow in order to provide some consistency in the program.  I worked with the board to help the club visibility in the community and we saw about a 20% increase in the number of players. I was responsible for the hiring of all Select coaches within the club.  I worked closely with the city to bring ECNL, R3PL and NC State Cup games to our home venue.

From August 2013 to July 2017 I was a Staff Coach with the Savannah United Soccer Club in Savannah, GA.  During my time with Savannah United I coached several teams a season, been the head trainer for their Academy teams, done numerous coaching evaluations and started a winter training program for high school players.

I joined the staff at Frederica Academy in 2004 as Athletic Director and Head of Soccer where I coached the middle school and varsity teams.  I led the Frederica boys’ varsity soccer team to 5 State Championships and 2 State Runner up trophy’s.  I led the girls’ varsity teams to 6 State Championships and one Runner up trophy in my 7 years at Frederica.  I also coached the varsity and middle school cross country teams for two years. The school won 23 State Titles during my seven years as the Athletic Director.  While I was at Frederica, I oversaw several capital improvements to the athletic facilities including a gym renovation, upgrading the baseball facility and the construction of new grandstands and press box on the soccer/football field.  In addition to the capital improvements I was responsible for adding new athletic offerings to the athletic department, these included football, volleyball, equestrian and track.  Frederica was awarded the GISA Athletic Award for Excellence twice while I was Athletic Director.

Prior to Frederica I was involved in the running of youth soccer clubs in the Atlanta area since 1999, working with Peachtree City Youth Soccer and The AFC Lightning Soccer Club, where I held the position of Director of Coaching for all of PTCYSA and Girls Director of Coaching for AFC.

I have been involved in coaching soccer since 1992, and have coached at the youth, college and professional levels.   It has also been my privilege to be involved in the management and day to day coaching of four professional soccer teams, The Atlanta Magic, The Atlanta Ruckus, The Richmond Kickers and The Hampton Roads Mariners. 

Before getting hooked on coaching I had a long playing career. I grew up in the Atlanta area and started to play soccer at age 7.  I played many years for the very successful Datagraphics Soccer Club where we won numerous State and Regional Cups.  As a high school player I was on the Southwest Dekalb team that won State Championships in 1979 and 1980 while winning 33 straight games.  I original went to Georgia State University to play soccer.  After two good years I decided to transfer to Clemson University as they were a perennial top 10 program.  At Clemson I was the team captain for two years and helped lead Clemson to a NCAA National Championship in 1984.  I was a two time All-ACC team member, was part of the Region 3 team for many years and was in the US National Team pool as well.   I also represented the United States at The World University Games in 1985.  I played professionally in the MISL and NPSL with Cleveland, Jacksonville, Atlanta and Kansas City.

I am the holder of the two highest soccer coaching licenses in the US, The USSF “A” License, the NSCAA Premier Diploma; Pass with Distinction (top 5%) and The USSF National Youth License.  I also am a coaching instructor for The Georgia Youth Soccer Association, conducting coaching courses around the state and have been a staff coach for Boys and Girls Region III ODP Camps. I am currently an assistant coach with the 2005 Region III Boys ODP Team.  I recently went on two international trips with Region III teams to Portugal and Italy.   I am currently scheduled to be a member of the Region III ODP staff again the July in Alabama.

I have had the privilege of working with 4 players (Morgan Brian, Kelly O’Hara, Jason Moore and Troy Gardner) who have represented the United States at various Youth World Cups.  I worked most recently with Morgan Brian (U17 Women’s World Cup, U20 World Cup Champion. FIFA Women’s World Cup Champions, current member of US Women’s National Team and Olympic Lyon), who was also The Gatorade Player and Athlete of the Year in 2011.
