John, Jim, Bill Hass

The opportunities of today are a direct result of the strong foundation created by John, Jim and Bill Hass. The Hass brothers managed Valley Construction Company for nearly 50 years, growing and expanding the company their father, Arthur Hass, founded in 1925. John, Bill and Jim are responsible for the company’s growth and success through good economic times and bad. Their vision and strategy to diversify divisions and execute multiple company acquisitions allows for the multi-faceted approach to client satisfaction that Valley Construction Company currently provides. All three continue to volunteer in the community and serve on multiple community and professional boards.
