Our Team
Charley Stevenson, LEED AP BD+C
Charley has been interested in sustainable design since the early 1990′s, when he graduated from Williams College with a BA in Philosophy and a Concentration in Environmental Studies. Since then, he has been involved personally in renewable energy and land conservation projects. He received his MS in Natural Science from RPI in 2002, allowing him to further pursue his interest in sustainable design.
He worked for years in education, as a math and science teacher, a high school administrator, and as a graduate school advisor. In all these roles, introducing technical ideas to new audiences was central to his work. He was involved in a number of significant volunteer projects, including founding a brand-new charter school in Adams, Massachusetts.
He began full time work in the design field in 2008, when he joined a small consulting engineering firm specializing in energy modeling and sustainability certification. Since then, he has managed the green aspects of many institutional projects ranging from 12,000 to 250,000 square feet. He founded Integrated Eco Strategy in 2010, to provide client-focused, high-value services relating to energy efficiency and sustainability. Drawing upon his knowledge and experience, project teams can set goals which are both ambitious and realistic. He brings the experience to help clients maintain the necessary understanding of this rapidly evolving focus area.

Katherine McCusker, LEED Green Associate

Kath is a recent graduate of the green building masters program at the University of Massachusetts Amherst. While at UMass she worked as a Green Building Researcher for Facilities Planning where she benchmarked the energy consumption and carbon emissions for all campus buildings, and managed an in-house retro-commissioning pilot project.
Kath has been working in the design field since 1999. She is a museum exhibition designer, with experience on a range of exhibit types from children’s museums to science centers to art and cultural museums. In fact, it was her first exhibition project – where she helped create interpretation for a National Parks Service LEED certified building – that introduced her to the world of green building.
She thoroughly enjoys seeing a project move from concept to its final three-dimensional form, and thinking about how to use less energy and fewer resources along the way.

Donald Mulhern
Don has been connected to the construction industry since birth. His father ran a small homebuilding business, but his interest led him away from the family business.
In 2012, after spending over 20 years working as a civil engineer, Don and his family left Pennsylvania to escape the natural gas industry and the impact it was having on their community. It was this controversy that started him thinking about alternative ways to solve our environmental and energy challenges.
It was after meeting Charley Stevenson (founder of Integrated Eco Strategy, LLC) in the summer of 2012 that Don became convinced that sustainability was the future of construction and decided to make it his life’s work.
Don’s favorite thing is spending time with family and friends.

Lisa Carey-Moore, LEED AP BD+C
Lisa is a LEED Accredited Professional with a specialty in LEED Building Design and Construction (BD+C). Prior to working on buildings and their impact, Lisa focused her energy on addressing issues outside of the built environment. Highlights of her work include serving as the Public Outreach Coordinator for the Norwalk River Watershed Initiative, a pilot project funded by EPA Region I, USDA’s Natural Resources Conservation Service, and the CT Department of Environmental Protection to address water quality and land use issues within a basin draining to Long Island Sound. In this capacity, she helped organize the watershed towns to work together to create a management plan to address issues such as nitrogen enrichment, habitat loss, and the need for public education and behavioral change. The program was recognized by EPA for its success at garnering municipal and public support, and it was used as a model for other watersheds draining to the Long Island Sound basin.
Lisa also spent considerable time lobbying state and federal officials to secure funding for municipalities to upgrade sewer and storm water systems in order to meet Clean Water Act mandates. She has extensive experience speaking to the public and writing on topics that impact the environment. Most recently, she completed her own LEED Home project that she hopes will serve as another means for educating the local community on how they can build and live with less impact.
Lisa serves on the Advocacy Committee for the Upstate Chapter of the U.S. Green Building Council, based in Syracuse, NY. She lives nearby with her family and enjoys being outdoors in any weather, to ski, hike, bike, and run. Lisa is also an accomplished rower, a sport she began during her time as an undergraduate at McGill University.
