Oakland Zoo Executive Team

Dr. Joel Parrott
President and CEO

The foresight of Dr. Joel Parrot has shaped today’s Oakland Zoo. An avid conservationist and naturalist, Dr. Parrot defined the role of Oakland Zoo in supporting local and global environmental education and conservation of animals in the wild.

Over three decades, Dr. Parrot has overseen the growth of the Zoo from 25 to 100 acres, increased the size and quality of animal exhibits, conceived and created the California Trail and established the Wayne and Gladys Valley Children’s Zoo to build opportunities for environmental connection for local children and children from around the world visiting Oakland. Dr. Parrot’s vision for an animal hospital that cares for animals and the environment came to fruition with the Zoo’s new LEED-certified, state-of-the-art veterinary hospital.

Dr.Parrot’s connection to the community and the animals of Oakland Zoo runs deep.His initial position began in 1984. As a consulting veterinarian, Dr. Parrot worked with animals and exhibits directly. His skill with exotic animals and his perception of what the Zoo could be first earned him the role of Staff Veterinarian and Assistant Director, eventually leading to Director and CEO. 

He received his BS and DVM degrees from Colorado State University, Fort Collins,Colorado.
