Meet the Greenburgh Nature Center Team

Senior Staff
Alix Dunn, Executive Director

Originally a Westchester County native, Alix spent over two decades in California working to protect and enhance our natural environment.  She spent many years as the President and CEO of Santa Monica based Heal the Bay, a non-profit dedicated to protecting the Santa Monica Bay and LA County coastal waters.  She also worked in a public/private partnership with California State Parks in Newport Beach at Crystal Cove Conservancy.

During her roles as an environmental activist, leader and educator, Alix’s focus has been inspiring the next generation to share her passion for protecting our natural world.  Alix and her husband re-located back to Westchester in 2019.  While exploring her community, her trips to the Nature Center sparked a desire to get involved professionally, and to bring her knowledge and background to a local organization that is a treasured resource in the community. 

Alix graduated with a BA in Political Science from California State University, Northridge and earned a Certificate in Non-Profit Leadership from Stanford Graduate School of Business.
