From inception to completion, he has perfected the “art” of professional program and project management applied to capital improvement programs.

SE3’s philosophy and operation policies are rooted in Mr. Stewart’s lifetime in the construction industry, beginning with the his family’s business, Masonry Builders Inc., established in 1949. Mr. Stewart founded and operated Engineered Polymers Company in the heart of Kansas City, employing over 80 people for nineteen years - with 90% of the employees from the inner city. His established leadership spanning several decades within the minority community in these communities further exemplifies his recognition as a highly talented business leader.
