About Us

A Legacy of Craftsmanship Since 1937

Henn & Sons Construction Services, Inc. has been shaping Northwest Indiana since 1937, but our story began even earlier with Henry Henn, a local carpenter who built a reputation for quality and integrity from 1908 to 1937. When Henry teamed up with his two sons, Richard and Raymond Henn, a family legacy was born. That legacy continued to grow with Henry’s grandson, Richard H. Henn, who joined the business in 1965. By 1987, the torch was passed to Robert Henn, who expanded the company’s services and workforce, making it a cornerstone of the community. Today, the tradition of quality craftsmanship is carried forward by John Henn, who became the fifth generation to join the family business in 2018.
