Kiira Antenucci

Originally from Colorado, Kiira grew up snowboarding, rock climbing, and kayaking with her family. After high school, she took a gap year, traveling with NOLS to Patagonia, Chile, and completing her EMT certification through Denver Health Paramedic School. She later earned a bachelor’s degree in Geology from the University of Puget Sound, where she deepened her love for the natural world and discovered her passion for instruction and teaching.
Kiira has been working as a mountain guide since 2019, leading expeditions in Utah, Washington, and Alaska. Her experience spans technical rock, alpine, and ski objectives, with a strong foundation in risk management and wilderness medicine. When she’s not guiding, she enjoys whitewater kayaking, skiing, trail running, and climbing. Her current pursuits are multi-sport adventures that involve glitter!
