Candace Stanciel founded The Common Good Agency (CGA), a consulting firm focused on capacity building for nonprofits and Higher Education institutions, in 2003. Through CGA Candace has led a number of efforts around DEI capacity building, public-private partnership development, brand activation, strategic planning and leadership development. Candace’s work with clients focuses on developing DEI capacity and competency for systems change. Increased DEI capacity, or the ability to identify, interpret and interrupt inequitable practices, is critical for all individuals, but significantly more valuable for those in spaces of social impact seeking to deliver outcomes for people not driven by factors of race, gender, SES or other markers of identity. Candace also serves as a Partner with New Profit, a venture philanthropy firm, where she co-leads the Capitalizing Diverse Leaders and Organizations (CDLAO) initiative.

Candace’s passion for social change is also exemplified through her volunteer work with Alpha Kappa Alpha Sorority, Inc., New Leaders Council (NLC), The Boston Pearl Foundation and Mother Caroline Academy. Candace earned a B.A. in African-American studies from the University of Georgia in 2002 and a master’s degree in higher education from the University of California, Los Angeles in 2006.
