Brennen Guy, PE (CO)

Project Manager

Brennen joined the 360 Engineering team in 2018, bringing his passion for mechanical engineering design to every project. Brennen finds it satisfying to see a project through the stages of concept to construction, especially knowing other people will benefit from a design he was a part of.


Not only does Brennen have a background in teaching, but he is also a natural leader and mentor to our mechanical engineering staff. An essential pillar of success for 360 Engineering is professional development. We aim to provide all staff members with the opportunity to grow personally and professionally. As a Project Manager, Brennen assists in building client relationships and seeing our projects run smoothly, but he also leads our internal coaching, training, and professional development. Additionally, Brennen contributes to our internal culture committee and is a master of planning fun events for our employees.


Brennen is a registered Professional Engineer in the State of Colorado. He received his B.S. in Mechanical Engineering and Chemistry from the University of Arizona.
