While most brokers are "generalists" who attempt to be all things to all people, Costello & Sons specializes in placing insurance in 4 distinct areas: Technology Companies, Venture Capital / Private Equity Firms, and Individuals.
Costello & Sons is a full service insurance agency and brokerage firm, offering a wide range of products and services to meet the needs of our clients including property and casualty insurance, group health, life, disability and long-term care.
However, here at Costello & Sons our coverage strategies certainly don't stop there! Costello & Sons has also developed an extensive risk management program that provides education and resources for agents and brokers. Costello & Sons is also one of 18 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.
We are also proud to announce that Costello & Sons was recently named one of the "25 Most Innovative Insurance Agents" in the U.S. out of 26,000 existing agencies.
With both Southern and Northern California insurance offices, years of dedication and the highest-quality service, what more could you possibly as for in an insurance agency? Here at Costello & Sons we value that simple fact that we're small enough to know our clients by name yet large enough to insure you with worldwide operations. No matter where you are located, across the State of California, Costello & Sons is standing by to help you access the best coverage at the right price.
