OUR PEOPLE
John Knowles
Education – B.S. Electrical Engineering, Texas A&M University, 2021
John interned at Purdy-McGuire in 2021 and got a full taste of what was to come. As a former member of C-Company for the Corps of Cadets and Fightin’ Texas Aggie Band, he understands the need to be consistent, disciplined, and a no-excuses team member. John brings these attributes and a passion for being his best to the Purdy-McGuire family.
John chose Purdy-McGuire for the opportunity to learn MEP design but also for the office culture. He enjoys seeing buildings around Dallas that his designs have contributed to!
