A nonprofit initiative in Sheridan, Wyoming, started by a founder whose family was hit by CADASIL.

Plain-language help for families living with CADASIL and other hard diagnoses.

Start with what you need today. The guides are free, sourced, and written for people who are tired.

The Goodyear Foundation (Sheridan, Wyoming) is an independent community nonprofit focused on CADASIL education, chronic-illness support, and local wellness. We are not affiliated with The Goodyear Tire & Rubber Company or its Akron, Ohio philanthropic foundation.

Programs we want to start

Each one starts when a few people step up to host it. The status on each line is the real one.

  2. Not started yet · Elders

    Elder Social Connection & Support

    Combating isolation through community gatherings and peer support.

  3. Not started yet · CADASIL

    CADASIL Education & Awareness

Help us start them

Each program needs a few people to get going: someone to host a circle, share a skill, open a room, or tell us what their family needs. If you've lived this, or you just want to help, there's a place for you.

Two gatherings planned at The Living Room, a community space in Sheridan that runs separately from the Foundation.
