Our Team

Tedor Whitman

Tedor Whitman became Executive Director of the Cora Hartshorn Arboretum and Bird Sanctuary October, 2014. He has over 25 years of experience teaching and leading conservation programs across a wide range of U.S. ecosystems. Tedor’s strong record as an advocate and leader in environmental education focuses on building collaborations between conservation organizations and education institutions focusing particularly on integrated biology and increasing participatory means of connecting science and environmental issues with people’s everyday lives. Before joining the Arboretum Tedor was among other things the director of education for Zoo Miami and Connecticut’s Beardsley Zoo, a high school biology teacher at the TERRA Environmental Research Center, and the director of Biological Stewardship at a large nature center in Westchester, NY. Tedor was also, for seven years, the director of education for the Wetlands Institute in Stone Harbor, NJ and is thrilled at being able to return to the Garden State. He attended the University of Pennsylvania and holds a bachelor’s in biology and a master’s in conservation biology. He and his wife, Marguerite, like to spend their free time outside arguing about bird watching strategies.


Melissa Czinn

As a child Melissa would lay under a tree in her front yard wondering how a seed could turn in to such a magnificent plant. Her wonder for the natural world is what led her to pursue an undergraduate degree in environmental science and a Masters in ecology and evolution at the Rutgers University. After graduate school, Melissa became an educator at Turtle Back Zoo and an adjunct ecology professor at Kean University. Melissa is excited to be able to educate and encourage others to appreciate animals and the environment.


Erin Dempsey

Being a nature enthusiast from a very young age led Erin to pursue a degree in Environmental Studies from King’s College, Pennsylvania. From there they had jobs as a nanny, private tutor, doing trail work and invasive species removal in California, and an Ambassador for the Passaic, Whippany, and Rockaway Watersheds in New Jersey. All of this ignited Erin’s love for teaching people about the environment. Erin believes that everyone can do something, no matter how small, to help the environment. They are excited to continue teaching and fostering lifelong environmental stewards of all ages here at CHA.
