Nick P.

Never worse for wear

Originally hailing from the small town of Ukiah, California, where wine country meets the redwoods, Nick began spending time outdoors at an early age.

He grew his outdoor credentials further with graduate studies in Forestry at Northern Arizona University. Nick’s knowledge of southwest ecology and natural resource issues and his deep appreciation for public lands shows through on each of the trips he guides. When not in the field, Nick is probably enjoying a craft IPA, experimenting in the kitchen, watching a Giants baseball game or out exploring with his wife and dog. Nick is a certified Wilderness First Responder.

Joy backpacking in her free time | AOA Guides | Hiking, Backpacking, Biking

Born at 5,280 feet above sea level, Joy grew up catching fireflies in Mississippi, exploring the beaches of the Gulf of Mexico and skiing Colorado slopes before moving to Montana for university after seeing a River Runs Through It. Between studying abroad in Africa, road-tripping out West and discovering really good coffee, she managed to acquire a degree in Rural and Environmental Change with emphasis in Mountain Tourism and Adventure Travel, which has provided her nothing less than the opportunity to pursue exciting activities wholeheartedly every single day. The road less traveled eventually led her to the canyons of Arizona and the stimulating profession of introducing others to her greatest passion. From guiding trips on volcanoes in Guatemala to teaching al fresco recreation skills in Hong Kong, Joy’s traveled, worked and lived in 40 countries plus over the last decade. When she’s not guiding in our nations’ most beautiful places, Joy can be found running ultra distances, sipping whiskey-on-the-rocks, freelance writing and routing future journeys on topographical maps of the Southwest US.

Nick M.

Over a decade ago, Nick Martin dropped the suit-and-tie for a baseball cap and bike shorts and started a career as Guide. He has been honing the art of canyon cooking, historical interpretation and packing coolers ever since. Nick’s sense of humor, irrepressible smile and articulate communication have convinced hundreds of big, little, old and young folks to trust their feet to climb down Mooney Falls, up Angel’s Landing and out of Grand Canyon. An outdoor recreation Jack of all trades, he constantly switches between his mountain bike, skis, running shoes, climbing harness and slew of topographical maps of the Southwest US. When he’s not exploring the confines of Canyonlands or guiding trips in our nations’ greatest parks, he’s probably skiing powder off the snowy ridges of the San Juan Mountains, diving with whale sharks in the Gulf of Thailand, trekking the Great Wall of China in a snowstorm, drinking cold beer on one of the 7,200 islands of the Philippines or practicing Spanish in Patagonia.
