Margaret is currently Executive in Residence at The Omidyar Group and Hopelab. In this role she provides strategic support and guidance to Hopelab’s partners and investees while exploring frontier trends and potential new initiatives in mental health and well-being.

From 2015 to 2025, Margaret served as President and CEO of Hopelab. Her tenure was defined by creating and leading initiatives focused on cross-sector collaboration—spanning health care, technology, venture investment, research, and youth engagement. Through this work, she built scalable solutions to improve access and equity and amplify youth voice and power.

Prior to Hopelab, Margaret held positions at the California HealthCare Foundation as Director of Public Financing and Policy and Director of Innovations for the Underserved. She launched the CHCF Health Innovation Fund, an early-stage venture fund focused on companies serving Medicaid and underserved populations. Her earlier career included roles at Accenture, the World Health Organization’s Global Programme on AIDS, and the Commonwealth of Massachusetts.

Margaret teaches entrepreneurship at Stanford University’s Graduate School of Business. She holds a Master’s in Public Policy from Harvard’s Kennedy School and an A.B. in English Literature from Princeton University.

She serves on the boards of United States of Care, Health Leads, Project Glimmer, and Kokocares.org; she is also an adviser to Young Futures, Acumen America and Hopelab Ventures, in addition to advising several early-stage health companies.

A few of Margaret’s interests include traveling, learning about new cultures, cooking for friends, spending time in nature, hiking and walking, and exploring the arts.
