Stack Society develops high-level athletes through intentional coaching, individualized development, and a competitive environment that brings joy back to the game.
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.

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.
Trevor blends his deep knowledge and coaching expertise with unmatched energy and passion, creating an environment where athletes can thrive and truly elevate their game.
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.
This isn't just a name. It's a daily commitment to becoming more — one layer at a time.

Stack Society Club Teams are for athletes serious about improving, competing, and reaching the next level. We limit roster sizes intentionally so every athlete gets meaningful coaching, individual attention, and real development all season long.
Roster spots are limited — teams formed through evaluations and invitation-based placement.
Stack Society Volleyball Club tryouts for the upcoming season. Our goal is to create a high-performance training environment for athletes who are serious about improving their skills, discipline, and competitive mindset.
Because we are building intentionally small, competitive teams, our tryout process includes multiple evaluation opportunities. Teams will consist of 10–12 athletes per roster.
Athletes only need to attend one initial session, though they are welcome to attend both.
