Much of the Lake Oswego High School boys soccer program's success over the past several years has been due to Coach Garrett Marcum. Garrett's responsibility has been to provide a steady stream of skilled players for Coach Fraser Morrison's varsity team. Each year Marcum's focus has been on the development and preparation of players for future varsity teams. Many of his players progress quickly enough to be promoted to the varsity team before the current year is even over. But not only does Coach Marcum excel in development and preparation, his teams have experienced repeated success as well.

It's not surprising as Garrett was an all-state player at Crescent Valley High School, where many of his records still stand. He averaged over 2 goals per game during his junior and senior years, leading his teams deep into the OSAA state playoffs, including winning the state championship his senior year in 1996. Born in San Diego, Garrett also played club soccer at the highest premier levels, travelling to Europe multiple times to play in international competitions. After graduating from Crescent Valley HS, he went on to play Division I mens soccer at the University of Portland, where he was a four year starter. After graduating from UP, he went on to play for the Portland Timbers for four years, before retiring from professional soccer.

Garrett works in sports marketing for Nike, and continues to provide the value of his soccer expertise to Fraser's coaching staff.
