Meet the Team

Herb Tiffany III President

Experience: 35 Years

Herb C. Tiffany, III, following in his father’s and grandfather’s footsteps, is the latest of three Herb Tiffanys to head up the company which bears his family’s name. Since assuming the title of President in 2012, Herb has begun to stamp his own management style on Tiffany Construction: fair, hard-working and constantly focused on steering the 89 year old company through the often challenging economic times currently afflicting the construction industry.

A native Arizonan, Herb began his construction career with Gosnell Builders in the Phoenix Metro area. In 1992, he moved to his family’s company where he has been ever since. Herb’s career has encompassed both building and civil construction. His breadth of experience in a wide variety of projects, both private and public, all over the state of Arizona makes him uniquely qualified to lead Tiffany Construction into what promises to be a bright and promising future.
