JC Vacassin Mastermind

I’ve worked in the fitness industry for more than 20 years.

I started as a PT training out of my car in the early 2000s; and opened my first Training Gym a few years later.

Today, I’m CEO of Foundry, with nine sites (and growing) across London and the SE.

I’ve coached and mentored hundreds of independent gym owners, many of whom have gone on to become successful founders and multi-site operators.

In 2022 I rowed the Atlantic after a double hip replacement, raising funds for CALM, and continue to work with several charities to build stronger communities. 

I’m passionate about helping other gym owners build and scale businesses.  

You can work with me via my Mastermind or standalone coaching.
