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. Under her guidance, Oakland Zoo has become known for its spacious habitats and behavior management programs which provide animals with freedom of choice and control over their environment.

In 1990, Colleen came to Oakland Zoo as the manager of the Zoo's elephant program, transitioning it into a protected contact system where keepers only use positive reinforcement with elephants and are always protected by a barrier. During her time at the Zoo, she has overseen the development of the African Savanna, Children's Zoo, California Trail, expansion of the elephant habitat, as well as construction or remodeling of many other habitats to continually improve animal experience. 

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.
