Welcome to the homepage for Matrix Basketball.  We are very excited to kick off the 2018 AAU season, our 16th season as an organization.  Our program serves girls from Grades 2 through 11 from across the region, fielding at least two teams for most age groups, led by an experienced volunteer coaching staff.  We look forward to providing more opportunities for girls in Northern Virginia and the DC Metro area to continue to develop as people and players in 2018!
