Tresban Rivera
Executive Director
Tresban is a passionate and innovative leader who has found her way back to her first love – animals- after a long and successful career in education.
Throughout her professional journey, she has been driven by a commitment to service, leadership and building strong community connections.
She is excited to bring together her love of people and animals in service to our Coconino County community, where she works to support the mission of the shelter and make a positive impact for both animals and those who care for them.
When she is not at the shelter, Tresban can be found spending time with her two rescue dogs, Missy and Luna.
Dr. Carly Bennett
Shelter Veterinarian
Dr. Carly Bennett graduated from University College Dublin in 2013. When High Country Humane opened in 2019 as the municipal shelter for Coconino County, she proudly accepted the full-time veterinarian position.
Dr. Bennett’s passion for shelter medicine began long before she became a veterinarian, and her deep commitment to the animals and people of this community continues to motivate her everyday.
Outside of the shelter, you’ll likely find her spending time with her pigs, goats, chickens, and her two Heeler dogs.
Megan Boyer
Shelter Manager
I joined High Country Humane in 2021 as a member of the dog team and discovered my love for animal welfare. With High Country Humane, I was able to grow into a leadership role, becoming Foster and Transfer Manager in 2023. In January 2025, I stepped into the role of Shelter Manager.
I love working alongside such dedicated and empathetic individuals as well as belonging to such an incredible community in Coconino County.

Marketing & Social Media Manager
Having been with High Country Humane since 2019, I have been fortunate to be able to grow with such a young, yet AMAZING organization. The love & care poured into every pet is inspiring, and I’m lucky to be part of this team. I’m extremely passionate about animal welfare and love being able to highlight these special pets, helping them find forever, loving homes! AND showing our community what really happens here at High Country Humane!
If I’m not running around the shelter helping out wherever I can, I’m most likely out hiking, traveling, or enjoying nature!
