North Boone High School - Varsity Head Coach

Matt Yarc is the Head Varsity Boys Basketball Coach at North Boone High School in Poplar Grove, Illinois . He grew up in Libertyville where he played high school basketball for four years and then played one year at the Junior College level before his career was cut short due to an injury. While playing, he was coached by two Hall of Fame coaches, Max Sanders (Libertyvile) and Bruce Smith (College of Lake County). Both coaches encouraged him to pursue his love for the game and help others by getting into coaching; his first head coaching opportunity came when he was 17 years old.  Over the past 30 years, Matt has coached at the Middle School, AAU and High School levels. During that time, he has operated his own Basketball Academy for 12 years and has coached and trained numerous players in the Northern Illinois area to play the game at their highest level.
