Thank you for taking action!

We all know that there's a slim window to safeguard democracy and protect our climate. Third Act is going to be key and we've identified a new, massive, and under-organized demographic: Americans over 60 who care about the future. If you can pitch in, this is the time.

Introducing the ‘No Time To Waste’ Fund

Help us raise our goal of $500,000 before December 31, 2023.


Why we must act now.

The struggles to safeguard our democracy and to protect our climate are inextricably linked. We’re all experiencing environmental traumas from climate change – the increase of wildfires and smoke spreading across the continent, extreme heat, diminishing wildlife, floods in some areas and drought in others. And we’ve seen the direct threats to our democracy grow stronger: gerrymandered districts, suppressed voting rights, election denial and interference threaten progress on all of our country’s issues.  

Third Act has found a gap in the progressive movement ecosystem—channeling the passion, skills, and commitment of Americans over 60—and the interest in our work is staggering. It is far beyond what our small staff team can currently harness. Now that we have a solid organizing model in place for moving folks into action, we are seeking to build our base, deepen our power, and make viable plans for engaging new and critical communities. 

The No Time to Waste Fund will help ramp up our organizing work to support 60,000+ Third Actors plus allies coast to coast—from staffing and training, to events and digital support. With your investment, we can build a mighty force of volunteers in all 50 states, especially in vulnerable communities and hot spots, that works for a just and sustainable America while building a legacy of a brighter future for everyone and our planet. Your generosity will help Third Actors respond quickly—as needed, when needed, where needed. 

Here’s a snapshot of how your contribution can help:

• $300 ($25 per month) can pay for food & materials for an in-person event or training

• $600 ($50 per month) can help cover costs for a working group’s demonstrations over several months

• $1,200 ($100 per month) can pay a trainer to educate hundreds of volunteers about effective campaigning, base-building, or local media outreach

• $5,000 can help cover travel expenses for frontline community members coming from a multi-state region for a demonstration

• $10,000 can support a multi-day, in-person training that brings together Working Group coordinators from multiple states

• $50,000 can support an additional part-time organizer to build and support new Third Act communities for a year

We know that building strong ties in communities is key to building momentum toward a cultural shift. Our approach is based on many decades of organizing experience held among our staff, and also in research published by movement veterans, and sociologists who study behavior change. And we know that our Third Actors are deeply committed to the experience: 

We now have over 70 Third Actors in our ranks here. And while we work to make a difference to protect both our planet and our democracy, I’m also struck by the difference that Third Act has made in our lives. Joining us in community with others, helping us to feel purposeful even at our advanced ages. Giving us a voice in a world that needs healing. Without this sense of agency, action is impossible. Third Act gives us that.”

-Marjorie R, 85, Co-Facilitator of Third Act Massachusetts

Yes. If you’re interested in or planning on making Third Act a beneficiary in your will or estate plans please email

We would be honored to work with you to create a lasting legacy in support of a fair and stable planet. You can include us as a beneficiary in your will or estate plans. A bequest is easy to arrange and is not payable until you pass away, so it does not affect assets or cash flow during the your lifetime. It is also private and revocable, since you can change provisions in the will or trust at any time, and it is not made public until death.

However we’d love to honor you by including your name among those in our Legacy Circle once you’ve decided to include us in your estate plans. Please do let us know when you’ve added us to your estate, and if you’d prefer to keep your name anonymous.
