Major Accomplishments

Dramatic Reduction in Foster Care Population

During her leadership, the number of children in foster care dropped by approximately 70–71%, a striking achievement that significantly reshaped the agency’s impact in Baltimore.

A National Model for Modern Social Services

Tierney implemented reforms that transformed the agency’s operations into a business model now considered a national exemplar for effective, modern delivery of social services.

Earlier Family Reunification

The reformed approach emphasized quicker return to families: 40% of children entering foster care were reunified within 90 days, an outcome reflecting both efficiency and child-centered strategy.

Innovative Neighborhood-Based Placement Strategy

Through the “Place Matters” initiative, Tierney’s agency partnered with Baltimore City Schools to locate familiar, community-based placements for foster children. Social workers were embedded in schools to enable fast connections with relatives or trusted adults, reducing trauma and improving placement stability. This innovative practice earned the agency a Bright Idea in Government Award from Harvard’s Ash Center.

Data-Driven Turnaround & System Rebuilding

When Tierney arrived in 2008, the agency faced systemic dysfunction—cases went untracked, children stayed in group homes for prolonged periods, and tragedies occurred even while under state care. Through disciplined, data-informed reform, she spearheaded a 72% reduction in foster care placements within a seven-year period. This success was grounded in clearer mission focus, strategic use of data, and consistent task completion.

Catalyst for Thought Leadership

Tierney’s ideas resonated beyond the local level. Her 2014 TED Talk, “Rethinking Foster Care,” critically examined the foster care system as a self-perpetuating ecosystem and challenged fundamental assumptions—sparking national conversation about child welfare reform.
