Theresa M. Ellis
Founder and CEO
Theresa has dedicated her career to bringing innovative, impact-creating solutions to the most pressing social problems. As a little girl, she worked with her parents to help a family of eight children get back on their feet after both their parents were killed. This experience gave her a sense of the transformative power the right capital invested in the right venture at the right time.
Theresa brings two decades of experience in the social impact space to Liminality Partners. After beginning her career in education evaluation, Theresa founded Common Impact, a social enterprise that was the first to build systematized, pro-bono programs for Fortune 500 companies. After serving as CEO of Common Impact, Theresa took an appointment as the Gleitsman Visiting Practitioner at the Center for Public Leadership at Harvard’s Kennedy School of Government. In this role, she taught leadership, worked closely with students interested in social enterprise, and conducted research on the role of multi-sector leadership in addressing complicated, societal challenges.
More recently, Theresa returned to Dartmouth and lead the reorganization of the Tucker Foundation. Through a multi-stakeholder process, Theresa launched two new centers: The Tucker Center for Spiritual Life and The Dartmouth Center for Social Impact. As the founding Director of the Center for Social Impact, Theresa set the strategy, recruited a team, raised early capital, and built a board of advisors.
As the Founder of Liminality Partners, Theresa advises families and individuals who want to leverage their resources and tackle the social problems that are important to them. She collaborates with her clients to craft and implement their philanthropic strategies, work through operational challenges and evaluate their effectiveness. Theresa earned an AB in Religion with honors at Dartmouth College where she graduated magna cum laude and Phi Beta Kappa. She received the Phillip D. McInnis Class of 1936 Award, given to the outstanding woman in the graduating class. Theresa serves as the Chair of the Board of Trustees of the Brookwood School and as a judge at several social enterprise competitions. She also served on the Board of Trustees of the Essex County Community Foundation. She lives on Boston’s North Shore with her husband, their two children, and their dog.
