More than 200 UnitedHealthcare employees, the New England Patriots Charitable Foundation and the New England Revolution Charitable Foundation will team up with Bentley University, Brandeis University and the Waltham Housing Authority to build a new playground at Prospect Hill Terrace. The new 2,576-square-foot playground in Waltham will include a spiral slide, monorail, rock-climber and many other components. The playground’s design is based on drawings created by Waltham children who participated in a “design day” event in July. This is one of three playgrounds UnitedHealthcare is building today as part of its “Do Good. Live Well.” program, an employee-volunteer initiative to help prevent obesity. Hundreds of UnitedHealthcare volunteers will build other playgrounds Union Beach, N.J., and Dix Hills, N.Y. “As we work with UnitedHealthcare on our fourth playground together, we continue to build upon our mission of encouraging children to live healthy lifestyles,” said Josh Kraft, president, New England Patriots Charitable Foundation. “We hope the playground will enrich the lives of children at Waltham’s Prospect Hill Terrace and demonstrate to all involved the benefits of volunteering.” “UnitedHealthcare is a fantastic partner of the New England Revolution, and we’re very excited to participate in its employee volunteer program for this project,” said Brian Bilello, president, New England Revolution. “We look forward to working together to construct a playground that will help the children of Prospect Hill Terrace participate in healthy activities.” “UnitedHealthcare’s employee volunteers are honored to help build a playground that will give local children a safe place to play and exercise outdoors with their friends and family,” said Stephen Farrell, president and CEO, UnitedHealthcare Employer & Individual of New England. Prospect Hill Terrace is the largest public housing development in Waltham, with 144 units for low-income families. The new playground will complement a new community center also being unveiled at Prospect Hill Terrace. Bentley University and Brandeis University students will manage the community center programs.
