“Living in a rural area has some great gifts and challenges. I believe in helping kids now versus later. I believe all kids can make good choices if given the tools, care, and guidance of adults investing in them. In our society some kids are getting lost along the way. Kids need a family, neighborhood, and community to raise them. The Rock House tries to fill in where there are gaps. We support the families and students. My desire is for our teens to be successful, happy, contributing members of our society.”

Cheryl grew up with her two sisters, mother, and Air Force officer father in Saint Paul, Minnesota, where her love of horses, camping, boating, and gardening began. Cheryl has lived in Clear Creek County for 41 years. Cheryl also has two children: her daughter is a paralegal in Colorado, and her son is a missionary in Mexico with his wife and three children. Cheryl has always loved kids and loves her grandbabies.

Steve was hired as our Mentor Coordinator in 2018.

“I reached out to Cheryl to speak with her about serving as a volunteer. After several meetings, Cheryl asked if I would be interested in serving as the Mentor Coordinator. During these talks with Cheryl, I could not help but be inspired by her selfless commitment to the kids of Clear Creek County. One day that we were meeting the front doors of the RH opened and several of the kids walked in, the sun was over their shoulders and they all had big, warm smiles on their faces. They were happy to be at the Rock House and happy to see Cheryl! I was hooked!”

Steve grew up with twelve (yes, 12!) siblings in Ohio, playing lots of football and competing in wrestling beginning at age six. In college, Steve competed on the wrestling team and enjoyed the experience of winning a NJCAA National Team Championship. His wife Jen and their four kids (Jacob, Jocelin, Gabriel, and Kylee) love living in Colorado now as they are all avid skiers and very active in sports and recreational activities, including hiking 14ers, conquering the relatively challenging Sawtooth between Mt.
