ECHL: Terrence Wallin Takes Assistant Coaching Job in AHL

Maine Mariners head coach Terrence Wallin is leaving the organization to take an assistant coaching job in the AHL with the Lehigh Valley Phantoms. Wallin, 33, has spent the last six years with the Mariners organization, including the last four on the coaching staff, and has served as the head coach for the last three seasons. The Mariners have made the Kelly Cup Playoffs in each of the last three seasons before falling short this season. During the 2022-23 season, the Mariners would win a franchise record 42 games before falling to the Reading Royals in six games. The following season, they took the Eastern Conference Champion Adirondack Thunder to seven games. Maine will begin the search for their fourth head coach in team history immediately.
