Bryn Shank has been a member of Cooperative Energy Futures (CEF) since 2020 and first heard of CEF when he was in high school. Bryn was inspired by the idea of what a “Cooperative Energy Future” rooted in energy democracy could look like. Bryn came to work at CEF in 2023 after working at the Center for Energy and Environment (CEE) where he spent close to four years doing residential energy audits as part of the Home Energy Squad (HES).
After working for 3 years on Outreach at CEF, he is excited to make the transition over to the Sustainable Homes team as a Program Specialist.

As CEF's Project Development Manager, Jillian Wilde guides our projects from initial brainstorming sessions through construction and ribbon-cutting! She pivoted from veterinary medicine to become a Climate Change Specialist with the EPA, where her passion for bringing renewable energy projects as life changing solutions in rural and marginalized communities was founded. She expanded on this drive with the Department of Energy, by acting as the Technical Project Lead to build microgrids on critical infrastructure. Jillian has devoted her career to bringing renewable energy to marginalized communities across the United States. Her alma mater gave her the title "America's Renewable Energy Sweetheart" for her work with Tribal Nations.
Outside of work she is an avid reader, sailor, dog sled racer, and boxer who maintains close ties with her Indigenous roots through ceremony, language, and her perception of the world and her place in it.
Paolo Speirn has been working on solutions to climate change for over fifteen years. After running farmers markets, advocating for sustainable food policy, and organizing for a Green New Deal, he began his energy career by supporting communities around the metro as they shifted to energy efficiency and renewables. Now, he’s using his community engagement expertise to pilot a super-efficient networked geothermal system. The project will slash users’ energy bills and make natural gas obsolete in their homes and businesses.
Paolo has roots and community in northern California, northern New Mexico, and southern Minnesota. When he’s not at work, you’ll find him climbing, biking, phone banking, making art, and taking a dance classes.
