Our Story

Tim Harmon founded Harmon Construction in 1987. He and his wife, Janet, moved to Kansas City from Seattle, WA in 1986 to build the General Motors Fairfax Assembly Plant. After settling here, he saw opportunity to start a company where integrity, respect and professionalism would set it apart in the construction arena. Under Tim’s leadership, Harmon has achieved that goal while setting a steady pace for controlled growth.
