ABOUT US

Do you come alive on the trail? Love hiking, birdwatching, camping, or simply spending your days surrounded by nature? If the idea of wearing hiking boots to work, spotting wildlife during your lunch break, and being part of a collaborative, mission-driven team excites you, then Boyce Thompson Arboretum may be the perfect place for you.

Founded in 1924 by mining pioneer William Boyce Thompson, Boyce Thompson Arboretum is Arizona's oldest and largest botanical garden. Situated on 374 breathtaking acres at the base of Picket Post Mountain and bordering the Tonto National Forest in Superior, Arizona, the Arboretum offers a truly unique work environment unlike any other.

Our living collection showcases extraordinary plants from the world's deserts and arid regions alongside the native beauty of the Sonoran Desert. Every day brings opportunities to experience nature firsthand, with miles of scenic trails, spectacular mountain views, and abundant wildlife throughout the grounds. It's not unusual to encounter javelina, bobcats, roadrunners, hummingbirds, and a variety of native and migratory birds while working and exploring the Arboretum.

As an independent nonprofit organization, we're united by a shared passion for conservation, education, horticulture, and creating meaningful experiences for our visitors. We value teamwork, stewardship, curiosity, and a deep appreciation for the natural world.

Located just 30 minutes from Mesa and one hour from downtown Phoenix, Boyce Thompson Arboretum offers the opportunity to build a rewarding career while enjoying the beauty, adventure, and tranquility of the Arizona outdoors.

If you're looking for more than just a job—and want to be part of a community that inspires connection with nature every day—we'd love to hear from you.
