Our Story
The Cerris brand.
Cerris is a subgenus of an oak tree, known for strong roots and adaptive abilities. The mark next to our name represents the very heart of a tree root and is the basis of its growth and integrity. The Cerris group of companies is strongly rooted, united around a common set of principles, and prepared to meet the building needs of tomorrow.
Our Legacy
Our legacy starts in 1932 when three brothers decided to start a plumbing business in Kansas City during the Great Depression. Through a dynamic blend of entrepreneurial spirit, integrity, quality craftsmanship, and teamwork, that small family-owned company has survived multiple economic ups and downs and the challenges that the construction industry faces time and again.
In 2000, our founding family gave us the greatest gift of all – a chance to become employee owners, and in 2002, we became 100% employee-owned. From humble beginnings rooted in the Midwest to a nationwide presence and diverse brands coast to coast, we love what we do and the communities we’ve helped build along the way.
