After working for more than a decade as an operator and superintendent with the L. M. Wilson Co., Carl A. Rasmussen decided to go into business for himself, and opened an office on a dusty road in Lancaster, California. Within five years, C. A. Rasmussen, Co., took over the operations of Marion Wright Construction, and Carl asked his sons Dean and Larry to join the business. Soon, the company incorporated, and Carl’s third son, Charlie, came fresh out of high school to work with his father.

Carl Rasmussen announced his retirement in 1977, and the three sons took over running the company. As the Southern California landscape changed and the housing market boomed, C. A. Rasmussen, Inc. grew with the times, moving its headquarters from Lancaster to Simi Valley, in the early 1980s.

The company expanded into Northern California when it acquired Piombo Construction in Santa Rosa. During the ’90s, C. A. Rasmussen employees and equipment could be found on jobs stretching from San Diego to northern border of California. When the Northridge Earthquake struck in 1994, C. A. Rasmussen, Inc. was a key player in cleaning up the collapsed freeways and helping Los Angeles commuters go back to work.

By 2002, Dean and Larry Rasmussen retired from the business, and Charlie became president and sole owner. Charlie decided to downsize the business and focus its operations to the Southern California region. He also brought in his son Adam, as the third generation of Rasmussen men took on the construction business.

After 30 years in Simi Valley, C. A. Rasmussen, Inc. built a new company headquarters in Valencia and opened its doors in 2007. Since that time, the company has worked on dozens of multi-million dollar contracts that continue to shape Southern California’s landscape. C. A. Rasmussen, Inc. has won numerous awards recognizing its work from the California Department of Transportation, American Public Works Association, and the Southern California Contractors Association.
