Of all the volunteer opportunities in Denver, this is one of the most exciting and rewarding. Interested? Learn how to join forces with Colorado’s oldest and most dedicated advocate for wild animals, below!

Prior to orientation all accepted volunteers will be required to pass a criminal background check and submit a $15 training fee. Scholarship support is available on request.
4. Zoo U (Orientation)
All adult volunteers must attend a one-day orientation called Zoo U. This program will give you an introduction to Denver Zoo, our mission, Adult Volunteer Program staff, and give you the foundational skills necessary to deliver the highest standard of guest experience.
