Our
Story
Ministry can be incredibly fulfilling, but is often also draining and even personally wounding. To those outside of church leadership, this may come as a surprise; to those in ministry, it is an all too common and regrettable truth. In 2004, Nathan King made the decision to leave full-time ministry and soon crossed paths with many others who had been called to ministry but were, like him, discouraged to the point of leaving ministry altogether. It was during these conversations that the seed was planted to develop a retreat center to support ministers as they face the highs and lows in fulfilling their calling. In the almost-20 years since, that vision has grown, and in the fall of 2023, Nathan and his wife Tammy asked Chris Collier and John McNail to join them to achieve the vision that has become today’s Ministry Support Services.

Director of Ministry Relations
Chris Collier
Chris Collier has a sincere love for all of God's people, and wants to live out the greatest commands of loving God and loving others daily. He is blessed to be married to his lovely wife Lydia. Together they are enjoying the challenge and excitement of raising their four children - Jackson, Cassidy, Brennan and Bridger. Most would say Chris is a little (or a lot) crazy, loving things like camping without a tent, canoeing down a river in the dead of winter and hiking for days with only the supplies on his back. But crazy or not, there's seldom a lack of adventure on the path ahead.

Director of Ministry Operations
John McNail
John McNail is a jack of all trades and master of none - he loves a good challenge and identifying solutions to unique problems. John is husband to Christi and father to Noah, Samuel & Matthew. He finds great joy in the creation of things - both physical and digital - spending his free time constructing modern furniture and tinkering with new technology. John and his family enjoy quiet weekends at home, hiking in the wilderness & spending time with friends and family!

Director of Development ​
Cole McCollum
Married to Christine for 27 years, we are blessed with three children—Ciara, Brianna, and Brennen. Our journey of following Christ has led us to incredible opportunities, from mission work in construction and remodeling to raising and breeding Scottish Highland cattle. It’s been amazing to witness the doors God opens when we remain willing to follow His lead.
I am passionate about reaching the lost, men’s ministry, and walking alongside others as they grow in faith. I love guiding hunts, fishing, outdoor activities, and staying active. I look forward to seeing how God uses this ministry to help others find rest, refreshment, and renewal.
