Our Team

Our staff come from a variety of backgrounds but each one has been drawn to this mission through a commitment to living their faith and pursuing excellence. Our instructors each have a minimum of one year of experience either in ministry, adventure facilitation, or both, and some have up to 20 years of experience under their belts.

COR staff and instructors are committed to making Christ the center of every course we offer.
