Professional Referee Organization (PRO)
The Professional Referee Organization (PRO) will be responsible for managing the referee program in professional soccer leagues in the United States and Canada. The creation of PRO is designed to increase the quality of officiating in U.S. and Canadian professional leagues, develop more professional quality officials at a younger age and develop officials who will represent the United States and Canada in FIFA competitions.
U.S. Soccer and MLS will govern and fund the organization, with ongoing collaborative support from the Canadian Soccer Association and other professional leagues. PRO will manage officials in the MLS and MLS Reserve games, the North American Soccer League, USL PRO and the Lamar Hunt U.S. Open Cup.
Veteran English referee Peter Walton is the General Manager of PRO and will be based in New York City.
