Building Smart | Building Together


TANCO | General Contractors™ is a commercial construction company tracing its roots back to 1947. Founded by the late Harry Tancredi, an Italian immigrant farmer who started in construction and gradually built his enterprise to the development of over 5 million square feet across Western U.S. Known as a straightforward businessman, Harry was a fixture in his Orange County California community. His diverse portfolio encompassed commercial buildings, schools, fire and police stations, strip malls, storage facilities, office buildings, master planned communities, multi-level parking structures, and industrial parks.


60 Years Later


Today Harry’s son, Adam Tancredi and partner, Colby Vogel, are committed to providing the same customer service, value and quality to their clients.  TANCO | General Contractors™ knows that construction is more than brick and mortar.  It’s a carefully thought-out process that requires teamwork, communication, effort and attention to detail.  When done correctly it produces a quality product, a happy client and a building that will stand for generations.  At Tanco, we know and embrace the fundamentals and build our teams to meet the industries challenges with collaboration, innovation and resilience.
