Hockey Operations Team


We are pleased to share with you that we now have a team of dedicated hockey professionals working with ACYHA to further develop our philosophy of hockey development and coach our coaches on that philosophy. We have taken these concrete steps for all of our players — Mites/U8’s through Bantams/U15’s — to create more consistency and structure. This includes the development of a coaches practice manual.

The following coaches will have contact with teams and coaches 2 to 3 times per month, including some games. They will be providing feedback on practice planning, practice tempo and game performance. We're excited for the next level of ACYHA hockey!
