Nate Brosey

OWNER

Nate started Stage 4 Designs in 2015 to better serve the needs of the growing obstacle community. His commitment to building the most exceptional and durable products in the industry is on full display at ACTION Wellesley (the gym he started with his wife and business partner, Sheri, in 2012) and ACTION Norwood. Nate's limitless creativity is only matched by his equally limitless energy to see others succeed on the obstacles he creates

Nick Masters

FABRICATION AND DESIGN FOREMAN

Nick is indeed a master! With over 15 years experience in the trades and almost a decade in the camp industry, Nick brings a rare combination of application and innovation to our designs and fabrication. His attention to detail and commitment to the highest quality is evident in every product we create.   

Simon Milgroom

OBSTACLE DESIGNER/BUILDER AND WEBSITE DESIGNER

Simon has been working with Stage4Designs since 2020. In that time, he has shown his dedication to hard work in both designing and building the best obstacles and training elements on the market. Always striving for perfection, we're happy to have him on the team.

Garth Stewart

Apprentice & All-Around Powerhouse

When it comes to getting things done, Garth is our boots on the ground. As an apprentice in the obstacle design and manufacturing world, he’s learning the ropes (and probably hanging from a few). Whether it’s assembling, painting and sanding, or hauling materials, Garth brings the muscle and the motivation to every project.

When he’s not building obstacles, you can find him out in the wild — hunting, fishing, or getting in a solid workout. Garth’s hands-on energy and can-do attitude keep our shop running strong.
