Our History

The Curb Masters, Inc. story began in 1989, when Randy Callies started a small concrete contracting company out of his own home. Randy had previously had a successful concrete business with a colleague until both partners decided to run solo. Randy's son, Mark, joined Randy and they have run the business side by side ever since. The company has steadily grown from there, developing a reputation for delivering a high level of service to its clients. As the company expanded its work in the Twin Cities market, it was clear that this uncommon level of service would be well received in other areas as well. Curb Masters, Inc. then expanded to serve Western Wisconsin. Today, the Curb Masters, Inc. team consists of over 70 employees serving the Minnesota and Western Wisconsin commercial markets. While Curb Masters, Inc. has seen its fair share of change, one thing will always remain unchanged - our commitment to service.
