Adam Altschuler

CEO, ALT HOUSE

About Adam

Adam is a high-performance tennis coach with experience at the highest levels of professional tennis, including working with Grand Slam champions and some of the game's leading players.

His approach has always centered on the individual. Rather than asking a player to fit into a system, Adam believes the system should fit the player — their game, personality, goals, and needs.

That philosophy became the foundation for ALT HOUSE.

Role at ALT HOUSE

As CEO, Adam leads the overall vision and direction of ALT HOUSE while remaining deeply connected to player development.

His goal is simple: bring exceptional people together across tennis, performance, recovery, and video analysis to create a completely private and individualized environment for every player.

About the role

Role at ALT HOUSE

As Head of Performance + Recovery, he designs each player's physical development plan and oversees every session in the gym and the recovery room.

He works alongside the tennis and video teams so the body being built is the one the game plan needs.
