Our Team


Executive Leadership Team

Summit Materials was founded in 2009 by Tom Hill. Tom has been in the heavy-side construction materials industry his entire career and recognized that there was an opportunity to form a new kind of construction materials company. A company that could acquire, integrate, and improve small family companies by providing access to capital, IT resources, and performance optimization practices, while leveraging the local knowledge of those companies and their employees. This decentralized structure requires a strong and experienced leadership team. Thus, Tom built the core Executive Leadership Team you’ll meet below and, using this decentralized model, has grown Summit from a single office to more than 400 locations.
