Costello & Sons Insurance Brokers

History:

Costello & Sons Insurance (CSI) is a third generation brokerage originally opened in downtown San Francisco. We have grown to over 2,000 clients and over $45,000,000 in insurance premium, which puts us in the top 15% of insurance brokers in the nation.

Specialization:

While most brokers are “generalists” who attempt to be all things to all people, CSI specializes in these distinct areas:

1) Venture Capital & Private Equity Firms

2) Technology Companies

3) Personal Asset & Income Protection

CSI is a full service insurance brokerage firm, and we offer a wide range of products and services to meet the needs of our clients including property and casualty insurance, group health, 401(k), life, disability and long-term care.

CSI is also one of 20 members of TechAssure, a global group of elite brokers endorsed by the National Venture Capital Association (NVCA) to deliver “best of breed” solutions and products for their members and portfolio companies.

With offices in Northern and Southern California, CSI is a regional insurance broker that is small enough to know its clients by name and large enough to insure clients with worldwide operations.

CSI is successful because we represent every major insurance carrier in each of our niches, while maintaining personal relationships with these carriers due to our volume of business.
