Jason Yale

National Program Director

Jason arrived at Big City Mountaineers after spending a decade working as an Outdoor Educator and Summer Camp director.  Jason has a passion for leading people in the outdoors, especially if that experience involves cooking copious amounts of cheesy pasta.  Over the years, Jason has had the pleasure of living and working in some of our most treasured wilderness areas in the country.  During that time, Jason took up Conservation Photography and continues to use his pictures to try and preserve our natural wonders.  He holds a bachelor’s degree from Montana State University and is a NOLS and Outward Bound alum.  Jason earnestly believes that skills learned in the wilderness are completely transferable to one’s daily life, and Jason always urges his students to ponder ways in which they can take and utilize their wilderness experience back home in order to better themselves and their communities.

Doug Sandok

Doug Sandok

Corporate Relations Director

Born and raised in Minnesota Doug’s first outdoor experiences were canoeing and camping in the Boundary Waters. He has a B.A. in Sociology from Colorado College and a minor in Urban Studies. Doug has built his life around being in the outdoors, traveling the world, and creating opportunities for others to learn and grow from challenge and adventure. Since early, pre Gore-tex, backpacking trips in the Rockies, to guiding and instructing in the Himalayas and South America, Doug has been shaped by the wild places and the people he shares those experiences with.  “There is no substitute for a wilderness experience – the growth that comes from a hard day moving through challenging terrain, and working with a team to reach a goal. Sometimes, it can be as simple as exploring your own ‘backyard’. and sleeping on the ground under the stars. Those are the elements that foster personal growth and deep friendship.” Doug’s professional background includes work with Outward Bound,  Where There Be Dragons, the Breckenridge Outdoor Education Center, Doctors Without Borders, and Paradox Sports. Doug takes his skills learned in these experiences and puts them to work empowering organizations to have greater impact through improving systems and program delivery, and through meaningful partnerships with supporters.

Dan Hernandez

California Program Manager

Growing up the youngest of six in an immigrant, single parent household, playing outside has always been an escape for me.  Even after lots of learning in schools (BS from Wake Forest and MS from U. Missouri – St. Louis) and even teaching in them, I can say the strongest lessons I’ve learned were on rope, on trail, and on a boat.   

After working as a conservation biologist for a decade in the US and abroad, and outdoor educator (cycling instructor, team facilitator, climbing guide, wilderness therapist, and sea kayak guide in California and Alaska) for the past decade-plus, I realize these lessons were made stronger because they reinforced the strong values I learned growing up in my family.  

These days I try to give back, including volunteering in state prisons, tutoring math in after school enrichment programs, and playing phone tag with the wonderful BCM volunteer community 😊 as I try to create exceptional outdoor experiences so kids like me can leverage the lessons learned as part of a team outdoors and use them to flourish in all parts of their lives.

Four Legged Staff

Dakotah Dog


Dakotah is KY born and raised (he bleeds blue – Go Cats!) but is loving his new CO lifestyle. If he’s not busy smelling everything CO has to offer, he can be found searching his co-worker’s trash cans for food scraps, policing the office dog pack, or cuddling by his mom’s side. Dakotah prefers all communication go through his assistant, Theresa.

Loki Dog


Hailing from a small mountain town in Colorado, Loki fosters an avid interest in snow and weather that is sub-50 degrees. He enjoys fetch, but is honestly more interested in having you chase him while he runs away with unreasonably large sticks in his mouth. A peacekeeper among the office dogs, he is always willing to share his bones. Loki responds most readily to the sound of a squeak toy.
