We’re all about building relationships. In an increasingly risky world, we seek to positively impact risk outcomes and accomplish our mission by “contributing to our partners’ success”. We do this by listening, understanding, advocating, and educating to improve and, ultimately, protect your bottom line.
100 YEARS OLD. 100% CONSTRUCTION.
In 1919, Robert Cobb and Oscar Strecker decided to leave large construction agencies and start their own company to help better serve the unique needs of their construction clients. They expanded their services as other client-focused visionaries came on board —including Richard Dunphy, and Rodger Zimmermann — each bringing unique construction risk expertise.
Since that time, Cobb, Strecker, Dunphy, and Zimmermann (CSDZ) has grown to become one of the largest privately-owned brokerages in America. From the federal highway expansion efforts to the reshaping of our modern skylines, CSDZ has a proud history of guiding and protecting construction companies whose heavy lifting and risk-taking have transformed this great nation.
ONE NATION. UNDER CONSTRUCTION.
Headquartered in Minneapolis, CSDZ is privately held and fiercely independent. In partnership with Holmes Murphy, we’re proud to be one of the largest employee-owned and controlled brokers in the nation with offices in 10 states.
When you choose to partner with us, you’ll be choosing the peace of mind that comes with knowing you’re getting specialized focus on risk management, protecting employees from work-related injuries, and cost containment strategies — all while increasing your bottom line.
