Arch Community Fund launched in 2017 in response to the alarming rise of overt racism, xenophobia, homophobia, misogyny, religious intolerance, and corporate dominance in the United States. With family members who narrowly escaped the Holocaust and went on to benefit from opportunities in the United States, the founders of the Arch Community Fund felt compelled to invest in efforts to challenge the rise of intolerance and fascism and help build a more equitable society.

Our Mission is to strengthen grassroots movements to resist oppression and build towards a more equitable future.

Core Principles

We believe that this moment calls for resistance. We must actively challenge the authoritarian threat posed by the current administration, and invest in long-term, tranformative change.

At Arch, our focus is on transformative organizing efforts that center:

  1. Resistance. Resistance in the face of injustice is a moral obligation. Inaction is complicity.
  2. Community Leadership: Movements for change are most effective when led by members of the affected communities.
  3. Systemic Change: Hate and intolerance arise from longstanding systems of oppression. Dismantling these systems requires bold, transformative solutions that address root causes and inspire action.
  4. Racial Equity: Structural racism is embedded in our culture and intersects with all forms of  inequity. It is important to use a racial equity lens and intersectional analysis in addressing inequities.

Our Work


Arch Community Fund makes grants to support transformative organizing for systemic change. Arch supports strategies that are community led, address root causes, and use an intersectional approach. Our grantmaking focuses on general operating support for small, grassroots organizations, including fiscally sponsored projects.

Social Investing

We consider the totality of Arch’s assets, not just grantmaking dollars, through a lens of social impact. We seek to aggressively invest our assets to support positive social change, and are currently developing an investment portfolio that maximizes our impact. We expect to release details on that plan by the end of 2018.

Who We Are

Arch Community Fund was founded by three siblings:

  • Alan Preston: Alan has over 25 years experience in nonprofit management, most recently serving as co-director of a homeless advocacy group in Seattle. He has also been an organizer for state and national tax fairness campaigns.
  • Leslie Preston: A lifelong social worker, Leslie spent two decades championing the mental health needs of low-income immigrant communities at La Clinica de la Raza in Oakland, CA. Forming Arch Community Fund was a top priority for her before her untimely passing in 2018.
  • Dean Preston: Dean is an attorney and activist at the forefront of the struggle for housing justice. He is the founder and director of California’s only statewide organization for renters’ rights. Most recently, Dean championed the nation’s first universal right to counsel law for tenants facing eviction.
