About Thill Contracting Co., Inc. 

Together. We Build.

Since 1980.

Our Story

Thill Contracting Co., Inc. is a family-owned commercial construction firm rooted in craftsmanship, trust, and long-term relationships. Founded in 1980 by master carpenter Robert Thill, the company began with a simple mission: to deliver quality work and treat every client with the respect and care they’d offer their own family. 

What started as a small venture led by Robert’s hands-on expertise has since grown into a multi-generational business, now led by his son, Greg Thill. With over 45 years of experience in the construction industry, Greg brings deep trade knowledge and a commitment to continuing the legacy of quality and integrity.
