Mission

History

GreenStar was founded in 2004 by Dmitri Martin. For the first few years, GreenStar built and sold Energy Star certified homes. In 2008, GreenStar made the transition from new construction to making existing homes more comfortable and efficient.

For Dmitri, this change was in response to his growing concern about climate change and his realization that retrofitting inefficient homes would have a far greater impact on CO2 emissions than building new homes.

Since 2008, we have helped several hundred homeowners in over forty cities throughout central Wisconsin to live more comfortably and efficiently.
