Company History

The company began in 2009 when the founder started performing energy audits from his garage. As customers asked for solutions to the problems uncovered in audits, the business grew to include insulation, plumbing, HVAC, and later solar installations. This natural expansion was driven by a simple goal: helping homeowners live more comfortably while using less energy. Today, Green Team LI remains focused on that original mission.

Leadership

Founder Jay holds a chemistry degree from MIT and a Master’s in Chemical Engineering. He worked in environmental cleanup during the 1990s and later in several startups before launching Green Team LI. His background fuels a practical, science-based approach to home performance. Jay’s local presence and hands-on involvement mean the company stays connected to the community’s needs.
