Colleen Kinzley directs the Zoo's animal care, wildlife conservation, and research programs. In this role, Colleen has driven a cycle of continuous growth and improvement for animal welfare at the Zoo. This means she also helps a staff of over 50 people responsible for habitats and animal welfare to continuously grow their understanding of what makes a healthy and emotionally-positive environment for all animals.

While earning her Master's degree from Cal State East Bay, she participated in research both at the Zoo and in Namibia studying elephant communication and social behavior.
