Marc McManus, PE



As the mechanical engineering lead in St. Louis, Marc McManus has partnered with architects and engineers to create successful projects for multiple disciplines and clients.  While responsible for engineering and its direction, Marc is a client engagement leader that oversees project management activities and also serves as an engineering mentor.  Marc’s skills are reflected recently by improvements made to a pharmaceutical campus chilled water system that resolved ongoing operational issues, improved energy performance, and paved the way for company growth.

I love designing, integrating buildings and mechanical systems. I take great pride in exceeding clients’ expectations and telling our success stories to new clients. CannonDesign’s varied project experience and wide-ranging services throughout our design process keeps me engaged and focused on providing quality work that provides real value.
