Company Culture

Seneca employees come from all walks of life, with vastly different backgrounds and experiences, but with one common goal: to support children and families. United by this mission, our programs celebrate creativity, encourage teamwork, and rise to meet every challenge along the way.

Employee Resource Groups

Seneca’s Employee Resource Groups bring together agency staff who share common aspects of their identity or life experiences. Group identities evolve depending on who is present, and each group has unique experiences and needs within the larger agency. Currently these groups serve as a place to hold space for identified members, form community, build relationships, and work collaboratively to raise issues and advocate for staff needs.

Employee Resource Groups are typically formed around marginalized identities and center the needs and healing of group members. They work to prioritize the humanity and well-being of our staff and be anti-oppressive in practice and be community-centered at heart.

Diversity, Equity and Inclusion at Seneca

Seneca Family of Agencies is committed to providing a continuum of outstanding mental health, permanency, education, and juvenile justice services to underserved communities. Recognizing that many of the children and families referred to our services are experiencing the effects of institutionalized and systemic discrimination, racism, and marginalization, Seneca strives to recruit and retain a workforce that is reflective of the communities we serve, and holds the provision of culturally responsive services as a foundational commitment across the agency. This commitment is reflected in our agency-wide DEI Initiative, DEI Advisory Board, Employee Resource Groups, and Language Practice Groups, which devote agency resources to support historically underrepresented communities and help our employees provide culturally and linguistically responsive services to the families we serve.
