Ashley Harris Philippsen is a senior advisor of implementation at the Institute for Responsive Government, where she works to strengthen how governments effectively meet the needs of their citizens. Previously, as executive director of ImpactTulsa, Ashley led cross-sector collaborations to place over 15,000 additional Tulsa youth on paths toward economic mobility by 2030. Under her leadership, ImpactTulsa established the Mayor's Office of Children, Youth, and Families and launched Tulsa's Children's Cabinet—creating cross-sector governance infrastructure where none previously existed. She secured $7.6 million in new public and philanthropic investments, launched the city's first eviction alert system connecting housing instability to student support, scaled the walking school bus program from one to eight sites, and increased county pre-K enrollment by three percent. This work earned recognition as one of only four Obama Foundation My Brother's Keeper Alliance Model Communities nationally.
Prior to ImpactTulsa, Ashley served as deputy chief of community development and policy for the City of Tulsa, spearheading inclusive urban planning and Tulsa Race Massacre initiatives that prioritized community voices in policymaking. Earlier roles at Met Cares Foundation, Leadership Tulsa, and Teach For America Oklahoma deepened her commitment to creating enabling conditions that support students' lives in and outside the classroom—a commitment rooted in her beginnings as a 2007 Teach For America corps member at YES Prep Public Schools in Houston.

Ashley serves as chair of the Tulsa Development Authority, as a trustee on the Tulsa Authority for Economic Opportunity, and as a board member of the Oklahoma Policy Institute, Tulsa Higher Ed Consortium, and Leadership Tulsa. She is a Pahara Fellow and Harvard EdRedesign Fellow.
Ashley holds a Master of Human Relations and a Bachelor of Arts in Letters from the University of Oklahoma, where she graduated magna cum laude and as a member of Phi Beta Kappa.
