Markel Insurance, the insurance operations of Markel Group, has entered into a strategic collaboration with Greenhouse Specialty Insurance Services, a program administrator specializing in environmental casualty risks.
Greenhouse Specialty combines traditional underwriting expertise with a proprietary technology platform that streamlines submission handling and enhances underwriting precision. Working with Markel, the firm will help build a program focused on navigating nuanced environmental risks.
The partnership is designed to deliver targeted, technology-enabled solutions for increasingly complex environmental exposures while equipping brokers and clients with tools to support sustainable, long-term growth.
A distinguishing feature of Greenhouse Specialty is its limited distribution approach. The firm focuses on selective access rather than volume, ensuring brokers receive high levels of support, bespoke underwriting solutions, and consistent service. This model allows underwriters to maintain quality and attention to detail, supporting the delivery of innovative coverage options for environmental risks.
Founders Josh Rubin and Geoff Bernardo bring complementary expertise in building successful insurance programs. Their shared vision centers on creating a platform that balances growth with responsibility, aligning with Markel’s values and long-term approach to environmental casualty insurance.
The collaboration provides brokers with differentiated tools to compete confidently in the environmental insurance market.
For insurers, the program highlights the growing importance of specialized underwriting, technology integration, and service-focused distribution models.
By combining Markel’s experience in environmental casualty insurance with Greenhouse Specialty’s innovative approach, the partnership strengthens market offerings and sets new standards for broker support and program design.
