Purple Aces coaches volunteer their time and talent and are not paid for their efforts to coach. That dedication has made it possible for our fees to be among the lowest in Wisconsin AAU Programs - while providing excellence in coaching.

Mark's Bio:
Mark Demerath's love of basketball began as a player for Seymour High School. As he moved to Ashwaubenon and had children, he passed on that enthusiasm for the sport and found his new passion for coaching. Former Ashwaubenon High School Girls' Varsity Basketball coach Jim Zawlocki and Mark decided to start a girls' youth basketball program in Ashwaubenon, which still continues today. Mark helped coach Ashwaubenon basketball at various levels for over 15 years, even receiving a School Bell Award for his recognition of service to the Ashwaubenon School District in 1998. He also was part of the coaching staff that led the De Pere Redbirds to the 2005 WIAA Division I State Championship.
Mark began coaching Purple Aces in 1994 with his daughter's eighth grade team and hasn't stopped coaching Aces since. He has expanded Purple Aces to include fifth grade through junior level teams. Coach Demerath encourages his athletes to push themselves to their full potential. His "old school" coaching style has gained him recognition by college coaches at the Nike Tournament for producing well-rounded players that take the basic fundamentals of basketball to the next level. He treats his players like family, attending their school sporting events and encouraging them to have great character on and off the court. Mark has inspired many players to follow their collegiate dreams. Coach Demerath's unique style has not only elevated the skills of his players, but has given the girls access to experiences, friendships, and memories that will last for a lifetime.
