Markel partners with Greenhouse Specialty

Markel has formed a new partnership with Greenhouse Specialty, a program administrator focused on environmental casualty risks.

Founded by Josh Rubin and Geoff Bernardo, Greenhouse combines traditional underwriting with a tech-forward platform and a limited-distribution model designed to give selected brokers differentiated access and stronger support. Markel says the collaboration will bring more precision, service, and innovation to a complex segment as both companies look to build a long-term, values-aligned program in the environmental market.

“We are thrilled to team up with Greenhouse Specialty. Environmental risks present significant complexity and challenges. Leveraging Greenhouse Specialty’s experience and innovative strategies, we have developed a program that effectively addresses these exposures while also enabling our clients to pursue sustainable growth with assurance. The Markel Style aligns well with Greenhouse Specialty’s values, and we look forward to a long and prosperous relationship together.” – Jeff Lamb, President of Programs, Alliances, and Insurtech at Markel.
