Beverly, MA — October 13, 2026
Tree Guardians is pleased to announce the acquisition of Iron Tree Service, one of Massachusetts’ most respected tree care companies and a recognized leader in customer experience, safety, and professional arboriculture. This acquisition marks Tree Guardians’ first partnership in Massachusetts and an important step in its continued expansion throughout New England.
Founded in 2012 by Eric J. Roensch and John Maestranzi, Iron Tree Service was built on a simple but powerful philosophy: “It’s All About Your Experience®.” What began as a commitment to delivering exceptional tree care quickly evolved into one of the most trusted brands in New England.
Over the past 14 years, John, Eric, and their team have transformed Iron Tree into a premier provider of residential, commercial, municipal, and emergency tree services throughout Massachusetts. Backed by certified arborists, highly trained crews, and a fleet of state-of-the-art equipment, the company has earned a reputation for combining technical expertise with exceptional service and safety standards. That commitment is reinforced by Iron Tree’s 100% Satisfaction Guarantee, reflecting the founders’ belief that trust and accountability are the foundation of lasting client relationships.
“From day one, we’ve believed that great companies are built with great people. The dedication of our team members, combined with a commitment to safety and customer satisfaction, has fueled everything we have accomplished. Tree Guardians shares those values, and we’re excited about what this partnership means for our teammates, customers, and the communities we serve,” said Eric J. Roensch of Iron Tree Service.
“When Eric and I started Iron Tree, we wanted to build a company that treated customers the way we would want to be treated,” said John Maestranzi of Iron Tree Service. “Joining Tree Guardians allows us to continue that mission while providing our team with additional opportunities and resources, all while preserving the culture and values that have defined Iron Tree from the beginning.”
The partnership also reflects a shared dedication to supporting the communities and environments served by both organizations. Iron Tree has long prioritized community involvement and environmental responsibility, including facilitating the planting of more than 30,000 trees over the past two years through reforestation initiatives and conservation partnerships.
“What immediately stood out about Iron Tree was their unwavering commitment to delivering on their promises,” said Charlie Haines, CEO of Tree Guardians. “John, Eric, and their team have built a remarkable organization rooted in trust, professionalism, and partnerships. Their reputation throughout Massachusetts is the result of years of investing in their people, their customers, and their communities. We’re excited to support Iron Tree’s continued growth while preserving the culture that made the company successful.”
Together, Iron Tree Service and Tree Guardians look forward to building upon a shared commitment to exceptional service, environmental stewardship, and professional tree care, ensuring healthier landscapes and stronger communities for generations to come.
