About Us

Built Different.
On Purpose.

We keep our program intentionally small so every athlete is known, coached, and developed as an individual. Stack Society was built for athletes who want to compete at the next level while rediscovering their love for the game.

"Development requires standards, structure, accountability — and an environment athletes genuinely love being part of."

Coach Trevor's analytical style forces the athlete to learn the 'why' behind the skill and drastically improves progression. His ability to break a skill down into the most basic language makes complex movements easy to understand.

Working with Trevor has been by far the best investment we have made towards our daughter's volleyball career. We have seen vast improvements both on the court and in her confidence.

The 2-day team camp with Trevor was an incredible experience from start to finish! His ability to break down skills, give clear feedback, and keep sessions upbeat made both days productive and fun.

Trevor created an environment that encouraged growth while still nurturing the balance between fun and competition. My time being coached by Trevor left me with a refined set of skills that carried me through a National Championship appearance season.
