Executive Director

Joe has more than 25 years of experience in the nonprofit sector. He originally started by working with the homeless in Washington DC after graduate school at George Washington University. He likes to say that his “unofficial” title at Calvary Women’s Shelter was “Chief Gopher” because of his diverse responsibilities which included office management, databases, facilities maintenance and opening the shelter. After Calvary, he spent almost 10 years in youth services in Illinois and Colorado including five years as a Camp Fire USA Council Executive Director in both Illinois and Colorado. In addition to working with the homeless and youth, Joe has led organizations that work with disabled adults, the poor and working poor and feral and stray cats (getting them spayed or neutered). He is a life-long chess enthusiast and is the former President of the Colorado State Chess Association. He enjoys the outdoors including hiking and biking. He also enjoys the occasional computer game. Joe has been married to Julia since 2008 and they cohabitate with two tolerant cats.

Reece Wells

Camp and Family Programs Manager

Reece is originally from Denton, TX, and has been obsessed with nature since he first started cataloging the animals found on his family’s Ranch in the scraggly desert of Southwest Texas. From city parks to winding rivers and expansive lakes to wild, remote places, he loves getting to experience the thought-provoking beauty that nature provides everywhere. Even more, he loves getting to share that beauty and intentionally provokes the thoughts of others. Reece majored in Environmental Science in college with the main goal of always wanting to work outside. Luckily enough, he has been able to do that, leading and directing Camping and Outdoor Education programs in Colorado, Texas, Washington, and Wisconsin. Colorado has always been one of his favorite places because of the amazing nature and unique people. In his free time, you’re likely to find him hiking, backpacking, skiing, biking, or chilling in a hammock with a good book. One of his favorite parts about working with kids at Camp is playing games, of which he always has a few up his sleeve.
