Sean is a founding member and partner of Liminal Collective.
He has spent a career building and supporting environments where amazing people can accomplish extraordinary things in service to our planet. He pursues this aim at SidePorch, a consulting group he co-founded that supports early-stage companies and investment firms. He is also CEO & portfolio manager of Estabrook Investors, a fund management firm that drives positive environmental and social impact alongside financial returns.
Formerly an exec at Jeff Skoll Group and the MacArthur Foundation, Sean serves on the board of Alliance for Peacebuilding, is a passionate dad, and plunges himself when possible into heterogeneous activities: scuba under the waves, surfing on top of them, hiking through the hills, birdwatching or hitting the martial arts mat.
