Zeno is made possible by individual donors, grant makers, and sponsors like you. We welcome donations to support our work – every amount helps more people become math powered. To contribute, please make a donation today. If you represent a grant-making organization and would like to learn more about our work with kids, families, teachers, schools and community groups, please contact Kate Sedney-Read. If you are an individual or sponsor looking to learn more about Zeno, please contact Ari Rosen. Thank you for your interest!


Our work at Zeno would not be possible with out our amazing volunteers. From math nights to fundraisers and everything in between, we simply would not be able to reach the wide range of teachers, families, and community members currently engaging in our programs without the many individuals who give their time to create math powered moments! If you would like to learn more about volunteering with Zeno, please visit the Volunteer Page.
