CDSC promotes better ways to understand and deal with conflict through skilled teams of pro bono mediators, training programs in mediation and conflict management, and broad community outreach. We are committed to making our services accessible to underserved populations and to addressing emerging community needs.
Our Mission
CDSC empowers individuals and communities to solve problems collaboratively through conflict resolution services and training. At CDSC, diversity, equity, inclusion, and belonging are core components of our mediation work and our decades-long belief in social justice.
We commit to providing a safe environment where equitable opportunities and outcomes are available to all members of our community regardless of race, color, religion, national origin, sex, sexual orientation, gender, gender identity, age, or perceived ability.
