Our Office Staff

David Cavill, Controller

David Ian Cavill (please, call him Cavill—rhymes with travel) serves NYC Audubon as controller and has a professional background in non-profit finance, operations, and management. Much of Cavill's connection to mission driven organizations comes from a sense of spiritual motivation. He is currently pursuing rabbinic ordination at the Academy for Jewish Religion, is a graduate of the Jewish Theological Seminary’s undergraduate joint program with Columbia University, and attended Yale Divinity School where he earned the degree of master of divinity.

Cavill currently lives in the Bronx which is the most up and coming of any borough in NYC. He is outdoorsy and enjoys hiking and camping but is also at home on the sofa watching cooking shows and the Netflix catalog. In 2014 Cavill completed a certificate in mixology from the Columbia School of Bartending and is grateful to have a skill to fall back on.

Kathryn Heintz, Executive Director

Kathryn joined NYC Audubon in September 2014. She is eager to advance NYC Audubon’s scientific research, to build its educational work and public programs, and to support its advocacy activities throughout the five boroughs—all efforts that share a common goal of preserving critical natural areas that provide wild birds with welcoming, safe, and healthy habitats.

Debra Kriensky, Conservation Biologist

Debra grew up in the Boston area, and her love of nature and animals started at an early age. Her specific interest in birds, however, came much later in life after trying to identify the species she had seen on a trip to Costa Rica. She has been birding and photographing birds ever since.

After college, Debra spent several years working in the film industry at companies such as Miramax Films and National Geographic Films. All the while, she remained passionate about the environment and in 2012 she decided to pursue a Master's degree in conservation biology. Debra started off as an intern at NYC Audubon through her thesis work on horseshoe crabs and shorebirds in Jamaica Bay. She is excited to be continuing this work and assisting with NYC Audubon's other conservation and research programs as a staff conservation biologist.

Debra holds a BA in communications from University of Wisconsin-Madison and a MA in conservation biology from Columbia University.
