Our Team & Mission


Green Homeowners United was started for a simple reason: to make it easy for people to do one of the most important steps to fight climate change and save money in the process. Join us in helping cut carbon emissions at home.

Green Homeowners United exists to make it easier for homeowners and homebuyers to improve their property with renewable energy, energy-efficiency retrofits and water saving opportunities; and we help people find fair financing to afford the carbon-cutting upgrades that normally would be out of reach. Click here to see if our green home upgrade program could be right for you. You can learn more here about how we seek to ensure all homes can be upgraded, and check out our latest happenings and success stories here.

We're also a proud union shop, providing health benefits, training programs for workers to expand their skills, and a pension for when they retire.

In the words of CEO Lynnea Katz-Petted:

"We are the largest provider of home repairs to eligible homeowners in Southeast Wisconsin and the only one that provides them for free. While we directly impact individuals and families, we also improve economic stability by keeping long-term, existing homeowners in their homes. This stabilizes neighborhoods and the tax base paid to the city.

Over time, health and safety issues develop from the inability to pay for repairs and other necessary services. Without our free services, many Milwaukee residents would suffer serious injuries or even be forced to move out of their homes that they’ve lived in for over 30 years."
