United, the Columbus, Ohio, native coached and was the recruiting coordinator at Wake Forest University and in 2016 helped build FC Cincinnati's roster from scratch with head coach and former United player John Harkes.

An NSCAA All-American midfielder at Ohio Wesleyan under his father Jay Martin, the all-time winningest coach in NCAA history, Martin went on to play for Real Salt Lake and teams in Iceland and Germany before following his passion to coaching. He returned to Ohio Wesleyan to begin his coaching career, and the following year moved to Wake Forest University in 2007 under Jay Vidovich.  During his time at Wake Forest, the Demon Deacons won one national championship, made three NCAA College Cups and won two ACC Championships while compiling a record of 102-39-22.

More than 15 Demon Deacons have gone on to play Major League Soccer since Martin began at the university, including current United defender Jalen Robinson, former United midfielder Collin Martin and 2016 rookie of the year finalist Jack Harrison, as well as 2016 USL MVP and Golden Boot Winner Sean Okoli (who he worked with this past season at FC Cincinnati before Okoli’s transfer to NYCFC). Ryan has also coached three Herman Trophy award winners in Marcus Tracy, D.C. United player Ian Harkes and the Herman Trophy winner, John Bakero, recruiting the latter two to Wake Forest.
