Tim is an innovator of financial instruments for impact. Over the last fifteen years, he served in a number of capacities at Calvert Social Investment Foundation, and conceived of and launched the Giving Fund — a roughly $100 million impact investment-based donor advised fund that has been spun out to a new organization, ImpactAssets, for which he serves as President. He was instrumental in building the $200+ million Calvert Community Investment Note sourced from 12,000 investors large and small (with more than $750 million invested into 300+ nonprofits and for profits globally). Additionally, he co-founded and serves as Managing Member of Good Capital, which manages its Social Enterprise Expansion Fund LP, and has two operating spin outs, the SOCAP Conference, and Impact Hub Bay Area, a co-working, meeting and community space for 1,000+ social innovators across two locations — and part of a global network of roughly 40 Impact Hubs across five continents with 6,000+ members. He received a BA from Wesleyan University, an MBA from the University of San Francisco, and lives in San Francisco with his wife Julie and sons Milo and Gus.
