Markel Insurance, the insurance operations within Markel Group Inc., has entered a strategic collaboration with Greenhouse Specialty Insurance Services, LLC, a program administrator specialising in environmental casualty insurance products.

The company offers a unique casualty insurance product tailored to the environmental insurance needs of construction and environmental contractors, consultants, and engineers. Serving all fifty states, Greenhouse Specialty provides a competitive package product consisting of general liability, pollution, and professional, as well as admitted auto and excess up to $5M.
Through this collaboration, Markel will be able to deliver innovative environmental solutions amid an increasingly complex risk landscape.
“We are thrilled to team up with Greenhouse Specialty,” said Jeff Lamb, President of Programs, Alliances, and Insurtech at Markel. “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.”
A key element of Greenhouse Specialty’s operating model is its limited distribution channel. “We’re not chasing volume. We’re building precision,” said Bernardo.
Rubin added, “Limited distribution is how we ensure our brokers get the attention, support, and solutions that truly make a difference.
“We built Greenhouse Specialty to prove that doing business the right way, putting people and purpose first, can drive exceptional results. Markel shares that belief, and this collaboration gives us the platform to scale it in a way that changes what brokers can expect in how they do business.”
Bernardo continued, “We’re honoured to work with Markel. Their people-first culture, long-term vision, and innovative mindset make them the perfect fit for Greenhouse Specialty. Their deep experience in the environmental casualty space adds tremendous value to this collaboration, and together, we’re ready to deliver innovative solutions that equip brokers to lead with confidence and redefine service standards.”
