Chief Finance and Administration Officer

Eos came to Taproot because she loves the impact created when organizations that do good harness the professional prowess of business experts. She spent many years using her professional skills for good and is still on the boards of a few school groups, such as the Parent Teacher Student Association (PTSA) and school site councils, as well as other nonprofit organizations. Through that work, Eos has seen firsthand how using skills-based volunteering and pro bono service can propel organizations forward.

Her educational background includes a BS in management, an MBA in corporate finance, and many hours of on-the-job training with cutting-edge employers. Eos brings Taproot over 15 years of experience in finance, HR, and operations at organizations such as the Rainforest Action Network, and the Mission Hub which runs a network of five Impact Hubs. Eos loves the variety of work and challenges that comes with her three-hat role. When she’s not rearranging spreadsheets, having deep HR conversations, or physically fixing a network issue, you can find her on a soccer field near you.

Eos’ favorite root vegetable is the humble carrot, although she is starting to learn to love the seductiveness of beets of all colors.
