Leadership Team

Heather Carrigan
Chief Executive Officer

Heather Carrigan is the Chief Executive Officer of Westside Children’s Center (WCC). Heather joined the agency in 2010, drawn to child development and child welfare work because of her passion for advocating for children and families entangled in the child welfare system, as well as an overarching commitment to fighting poverty and other structural barriers to equality.

Under Heather’s leadership, WCC has achieved dramatic financial and programmatic turnaround. She led the agency to retirement of a $1.4 million debt (during the Great Recession), and through what has now been a 56% growth in the organizational operating budget. She spearheaded a complete rebuild of the organization’s administrative and financial infrastructure, establishing internal controls and protocols, significantly improving data collection and program management capacity, improving intra-agency communications, developing HR policies, and restructuring the agency bylaws. During Heather’s tenure, WCC also deepened its program quality by aligning all programs with best practices and fostering an agency-wide commitment to excellence. Today, WCC’s services are more comprehensive and there is deeper cross-program integration, so every family served receives a full range of critical, tailored, interdisciplinary services, and all child outcome goals are met/exceeded. To ensure WCC effectively meets clients’ deep, persistent, and specific needs, this strategic reorientation also included an investment in, and build out of, structured professional development and support for WCC’s dedicated, committed, and very diverse (80% people of color) staff. Prioritizing this responsive, client-centered approach is what led to the development and launch of WCC’s innovative infant mental health clinical internship program, which identifies and treats dual-generational trauma. All of this work culminated in accreditation by both the National Association for the Education of Young Children as well as the Council on Accreditation, ultimately recognizing all of WCC’s programming and administration as meeting the highest standards of excellence.

Prior to joining WCC, Heather held a 12-year tenure at the American Civil Liberties Union (ACLU) of Southern California. In her role as Chief Operating Officer, Heather led the senior management team in setting legal, policy, and fundraising strategies and managing the agency’s daily operations. She was intimately involved in overseeing policy research and analysis, as well as directing the agency’s communications strategy and overseeing legislative and initiative advocacy work aimed at influencing systems change. During her tenure at the ACLU, Heather served on executive committees of multimillion-dollar California initiative campaigns, including initiatives pertaining to immigrant rights, women’s health, civil rights for gay and lesbian Californians, racial equality, and criminal justice reform. The ACLU of Southern California advances a broad range of issues, and is responsible for groundbreaking work including the landmark Williams v. California lawsuit, which made headway in ensuring educational equality with a $1.2 billion settlement for the lowest performing California public schools as well as changes to school accountability measures. Heather holds a Juris Doctorate from Southwestern Law School and a Bachelor of Arts in Politics from Princeton University.
