Our Pastors




Colt Stubblefield, our Youth Director since 2005, leading weekly gatherings, mission trips, ski trips, and retreats. Of the many aspects that make up Colt’s life, his love for the Lord, his love for his beautiful wife Jess and their children Liam and Emma Kate, and his love for creation are the most significant. They are also the parents to two very active German Shepherds, Leonidas and Solomon. Colt loves to surf, longboard, ski, kayak, and rocks anything that involves a Frisbee. (Basically anything outdoors that poses a challenge to his existence makes him come alive.) Colt’s door is always open; come discuss the amazing things God is doing in the lives of our youth here at HACC, or sign up to join in any of their many adventures!
