Deirdre Butler - Born in England and living in rural areas next to farms and the moors, Deirdre spent most of her time outdoors having “adventures” either on foot or horseback. Her mother, a keen and observant naturalist, would take the family, accompanied by numerous dogs, on long walks and so developed Deirdre’s passion for all things wild and wonder-full. Work in the medical industry, brought Deirdre and her husband, Peter,  to America in 1997 - ostensibly for two years. Arriving in Colorado in 2000, Deirdre's desire to serve and her love of wildlife and nature led her to volunteer for a variety of wildlife and conservation focused organizations at both a local and national level. Deirdre has led over 50 day hikes and 40 mostly two-week long international trips including three successful summits of Mt Kilimanjaro.  Deirdre specializes in trips in her old home-country and has led England’s Jewel in the Crown - Coast to Coast trip, over eight times. A certified Wilderness First Responder, Deirdre lives in Lyons, CO with Peter and their menagerie of furry and feathered friends.

Valerie Pellegrin (Combs) - Born and raised in a small village in the South of France, Valerie is no stranger to nature and creativity. Coming from a family of chefs and artists, she was naturally driven to study Art History at the University of Aix en Provence. Here, she honed skills that would compel her to open an antique shop, and eventually an art gallery and picture framing studio which she currently operates in the quaint town of Lyons, Colorado. Moving to Colorado in 1992 gave Valerie a wonderful opportunity to expand her English speaking skills, cultural experience and love for hiking, foraging and exploring the great outdoors. She loves to cook and share “the art of the table” with others both in the USA and abroad. Valerie’s passion for fine cuisine is also reflected in her years’ long work at a fine dining establishment just outside Boulder, CO. Her enthusiasm for sharing the depths and nuances of French culture, art and history bubble through in her conversation, perhaps best achieved over a French baguette, French cheese and a fine bottle of wine, French, of course.
