About us

Nonviolence is a way of life

We are a group of committed individuals who care about a diverse set of issues of justice and peace. We are a blend of lifelong activists and new leaders with extensive experience in social ministry, justice, outreach and nonviolence. What unites us is our passion to stand in solidarity for social change and to teach others about active nonviolence, as a worldview, way of life, and a means of working toward that change. We collaborate with Campaign Nonviolence, Pace e Bene foundation, and activists from San Jose Peace and Justice Center, Metta Center fro Nonviolence, and the Diocese of San Jose. We are Joanna Thurmann, Lorin Peters, Monica Rising, George Stachnik, Stan Taylor, Andre Sosinski, Chris Katsura, Kim Vanderheiden, and Ashley Walker.

Kim Vanderheiden

I explore the connection between justice and relationship through art, writing and community action. My visual art, including drawings, painting, & printmaking, is often a form of meditation or contemplative prayer. My writing includes articles, meditations, and prayers and often reflects on justice, connection, brokenness, and restoration.
