I give talks, write books, and organize events to help you expand your positive impact on Earth.
I'm available to speak to small or large groups, offering comprehensive, science-based presentations about solar power, composting, recycling, electric vehicles, battery technology, plant-based diets, organic gardening, and other sustainable practices that may interest your audience.
My company, Sustainable Practice, publishes books and a web app for sustainable practitioners. If you take practical steps, large or small, to respect and protect Earth's ability to sustain life, you're a sustainable practitioner who belongs in our community.
Each spring Sustainable Practice presents the Earth Day Festival in Brunswick, Maine, where we share knowledge and inspire action to protect our planet.
I'm the lead author for the Sustainable Practices series of books.

I'm working to create the world's best Web App for Sustainable Practitioners to help everyone achieve their practical sustainability goals.
In the early 2000s, I created and then sold F.W. Horch Sustainable Goods & Supplies, a fun sustainable living store on Maine Street in Brunswick. In 2014, I co-founded Spark Applied Efficiency, an electrical contracting firm focused on helping companies efficiently use clean energy.
In 2023, Peggy Siegle and I launched a Maine partnership called Sustainable Practice, with a mission to empower action-oriented people with superior publications and tools for sustainable living. Our vision is a future when all people meet their needs in ways that protect and enhance Earth's ability to sustain human life.
I chose Swarthmore College to study engineering, ended up majoring in Political Science and concentrating in Computer Science, and then earned my Juris Doctor at UC Berkeley. While I was in law school I was a legal editor at Nolo Press and a summer law clerk at Pacific Gas & Electric.
