Meet Our Staff

Get to know the team that makes it happen.

Tiffany Staman

Executive Director

I was born and raised in Northern Illinois, where Christian camp experiences were a formative part of my life and faith development as I grew up. At sixteen, I felt God calling me to use my one and only life to serve the Kingdom of God. I earned a bachelor’s degree in Youth Ministry from Judson University, and spent the next sixteen years in pastoral ministry. Always in the back of my mind was a dream to someday be involved in christian camping.

Born from my passion to help people grow, I founded Breathing Space in 2006 with the mission to provide the space and tools for people to listen and respond to God through spiritual retreats and conferences. In 2008, I received a master’s degree in Global Leadership from Fuller Seminary, after which, I began working in the nonprofit sector where I learned fund development and non-profit leadership. After several years in organizations that served the homeless, I became the Executive Director of The Pregnancy Care Center of Rockford. In 2018, I received the national certification as a Fund-Raising Executive (CFRE) and was humbled to be named as one of Rockford, Illinois’ “Twenty People You Should Know.” I answered the call to be the Executive Director of Calvin Crest, moved across the country, and started in January of 2019. I am currently working on my doctorate of ministry in Spiritual Formation from Azusa Pacific University and love applying what I am learning to the ministry context at Calvin Crest. I am married to my soulmate, Cam, and have three adult children, Taylor, Payton (and wife, Alix!), and Graham as well as two dogs, Aspen and Wrigley.

Cam Staman

Operations Director

Cam began working at Calvin Crest in March of 2019. Before he and his wife, Tiffany, moved to California, Cam spent twenty years in management in the telecommunications industry and also owned his own fine woodworking business, He loves to create beautiful spaces for people to connect with God and others and mentor the younger staff on his team. He is honored to be a witness to the great legacy of Calvin Crest and its emerging future. Cam loves to camp and hike in the national parks, go boating and wakeboarding, and create inspiring woodworking projects. He loves to go to the coast with Tiffany and enjoy the beauty and art found there.

Rev. Joshua Kerr

Program Director

Growing up in a church with close ties to Calvin Crest, Joshua saw both in his own life and the lives of those around him how much of an impact it made in the support of the local church. As a camper, experiences of God’s grace in Sherwood, Jr High Sno-Go, and AIM were key turning points in his growing faith. As a young adult, serving on staff for six years was life-changing. Calvin Crest is where his faith became his own, where he formed his closest friendships, where he met and married my wife, and where he set out on the road that led to ordained ministry. It is an honor to serve now as Program Director, and he is excited to see what God has in store in the years to come!
