Welcome to
Sunshine Fieldhouse
Sunshine Fieldhouse is a groundbreaking indoor sports training and event facility located in Middleburg, Florida. Founded by Joe Grassia, a retired Navy veteran, Sunshine Fieldhouse offers an 88,000+ square foot climate-controlled building with professional-grade equipment, flexible training environments, and a space for community-building year-round—no matter the weather. The facility features an indoor turf field, batting/pitching lanes, pro-level equipment, weight & agility zone, arm care & recovery area, meeting rooms, party rooms, and more. It caters to a wide range of audiences, including youth athletes, high school & collegiate athletes, travel and rec sports teams, coaches, trainers, umpires, cheer & performance groups, corporate team-building events, and more.
WHY
We saw a void — and filled it.
In Northeast Florida, athletes train in warehouses with broken nets, no A/C, and outdated gear — or worse, they drive hours just to find space to grow.
Sunshine Fieldhouse is the solution.
We’re building 88,000+ sq ft of indoor, climate-controlled opportunity — right here in Middleburg. Designed for baseball, softball, football, soccer, and more, this facility will offer:
-
Year-round access
-
State-of-the-art training tech
-
Monthly clinics and camps
-
Mentorship from coaches, veterans, and pros
-
A community built around development — not just competition
This isn’t just a building.
It’s a commitment to every athlete, coach, umpire, and family who’s ever needed more than what’s been offered.
Sunshine Fieldhouse.
We saw the gap. And we built the answer.
