President, Solar Construction Services
With strengths in both sales and construction management, Brian is directly responsible for all contract review and negotiations at OnSite Solar. Brian began his career selling and managing large commercial and industrial design/build projects in the late 1990’s, after receiving a Bachelor of Science degree in Construction Management from Utica College of Syracuse University. It was then that he learned the critical fundamentals for delivering successful construction projects. As the Solar industry started to grow in New York State, Brian applied those fundamentals, and years of experience as a General Contractor, to successfully deliver OnSite’s first Distributed Generation Solar build in 2017. From that point, and ongoing today, Brian is focused on developing the people and procedures that are the
driving forces for OnSite Solar’s continued success. Brian is also instrumental in the planning and development of new business
and customer retention.
