Tim began his construction career in the early 1990s working for his family’s insulation company in Michigan. From his teens, he was hands-on—installing insulation, repairing equipment, estimating, and selling. After high school, he worked as a rough carpenter on custom homes before co-founding a general contracting company, with projects ranging from high-end custom homes to large residential and commercial remodels.

In 2005, Tim and his family moved to Phoenix, where he managed projects for a residential and commercial firm before overseeing the final year of construction of a 28,000 sq. ft. home on an 8-acre estate in Paradise Valley.
