Scott Maskin

CEO and Chief Fun Officer

Scott Maskin co-founded SUNation Solar Systems in 2003 and currently serves as President and CEO. As the company operations leader, his hands-on approach has driven SUNation’s growth and branding. Scott has a PhD from the School of Hard knocks. From 1980-1987 Scott traveled as an electrician and pyrotechnician for large touring musical, theatrical and industrial tours. The climate of conquering insurmountable tasks on a daily basis honed Scott’s organizational and communication skills and laid the foundation for everything that was to follow. Post 1987, Scott worked as a traditional electrician and obtained his Master Electrician’s license in 1994 and went out on his own. The next 18 years were filled with countless electrical and general contracting projects including hotels, large retail box stores, restaurants and thousands of residential installations. Just completing projects was never enough for Scott. Being a complete solution provider and never forgetting the importance of total customer satisfaction, will always be paramount to Scott. Solar became a passion and a direction in 2001. The mission of making the world a better place for his family, friends and fellow Long Islanders gave birth to what SUNation is, a collaborative of like-minded people who enjoy similar passions for family, the workplace and the environment. When not acting as Captain on the SUNation ship, Scott is an avid family man spending time boating, beaching and skiing and just enjoying what experiences come his way.
