There is no "trouble with Tribbles" (or Vulcans for that matter) at Tribble & Stephens. The company offers design, preconstruction, and construction management services, as well as greenbuilding and commercial renovation services. It operates primarily in Texas but has completed projects in throughout the Southeast. The firm administers the building of structures from condominiums and warehouses to high-rise office buildings and movie theaters. Tribble & Stephens also does much of its own concrete and carpentry work. Fellow University of Texas architectural engineering graduates Jay Tribble and James Stephens formed the company in 1972.
