About us

Why GenStar®?

GenStar®, Insurance Services, LLC, is the premier provider of excess, surplus, and specialty property and casualty insurance. We conduct business exclusively through a select group of wholesale brokers. As a wholly owned subsidiary of General Reinsurance Corporation, a member of the Berkshire Hathaway Family of Companies, GenStar® offers unsurpassed financial stability and capacity.




Our values are derived from the following disciplines:

Underwriting:  We are an underwriting organization. We provide insurance for risks we understand and at a price that fairly compensates us for the risks we are assuming.  All functional areas of our business—support and adhere to this discipline.

Marketing:  We believe that strong business relationships with our wholesale brokers and customers are critical to success.  We seek to place business through brokers who value our financial security, our expertise, our service, and our products.

Operations and Financial:  We have unparalleled financial strength, which we will deploy to grow our business profitably.  Despite this, we spend corporate dollars like our own. We strive to make cost and efficiency competitive advantages while maintaining, or improving, quality and service. We manage ourselves conservatively to ensure we are able to pay losses today and into the future.

Culture:  We treat our people, our wholesale brokers, our insureds and all others with transparency, honesty, and respect.  We enjoy what we do and challenge ourselves to be the best we can be.  We encourage teamwork.  We take pride in the fact that our success contributes meaningfully to the economic prosperity of our customers, our associates, and our shareholders.
