Volunteer Opportunities

Caring. Committed. Passionate. Powerful. The members of Denver Zoo’s volunteer community are as dynamic and diverse as the city itself—and as much a part of our family as our wonderful staff and our 3,000 wild animals. 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! 

1. Learn About Our Volunteer Program

There are a lot of options for volunteers at Denver Zoo! Volunteers are involved in almost every aspect of our operations. To learn more about the volunteer program, available opportunities, and more, view our Opportunity Guide HERE.

2. Ready to apply? 

Applications are currently CLOSED. 2025 application windows:

  • January 10th-24th

  • Fall 2025 – TBD

  If you would like to be notified of future application openings, add your name to our interest form HERE.

3. Acceptance and Next Steps 

All volunteers who are accepted into the Adult Volunteer Program will be notified of next steps via email. Each application cycle the number of applications we receive far outnumber the amount of open positions we have. If you are not offered a position, you are encouraged to apply again. 

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. 

For more information, contact our Volunteer Coordinator, Brianna Cronin at (720) 337-1619 or bcronin@denverzoo.org
