Meet John
Most people building a home gym end up managing five different relationships — a salesperson, a flooring guy, a mover, an installer, and a repair tech. John Mavros collapses all of that into one conversation. He's been doing this on Long Island long enough to know every piece, every brand, and every vendor worth calling.
He shows up. He measures the room. He pulls up the 3D layout on the spot. By the time he leaves, you know exactly what your gym is going to look like — and what it's going to cost.
The Process
Three steps. One contact. No project management required on your end.
Free in-home consultation anywhere in Nassau or Suffolk County. John walks the room, measures the space, and talks through your goals — equipment, budget, timeline. No sales pressure. Just a conversation and a plan.
John uses an iPad-based 3D design tool to build the layout in real time — right in your space, while you watch. You see exactly where everything goes, how it fits, and how it flows before anything is ordered. No surprises.
Equipment sourced, flooring installed, everything delivered and assembled. John coordinates Gym Tech Fitness, PreownedGym.com, and FitMovers123 so you don't have to make five calls. One message. It gets done.
Built on the Partner Network
John doesn't do everything alone — he does everything through a vetted network of specialists so every part of your build is handled by someone who does that thing all day, every day.
