David Milliken

Dave started Horizon with his parents and sister, Diane, in 2006, focusing primarily on energy audits and green building certifications. Since then the business has grown and moved from assessing and recommending improvements for home efficiency to contracting the work ourselves. Dave's is the voice you'll hear when you call with questions or seeking help, and his depth of knowledge and experience in building sciences is invaluable. He lives in Cape Elizabeth with his wife Kristie and three young children.
