After nearly 40 years of combined military, corporate, and academic experience, Greg answered God’s call to become a C12 Chair and see the Kingdom of God advanced in the lives of business owners and their companies. Greg comes to C12 with a breadth of experiences that includes co-leading a P&L responsible for a $50+ million business employing 350 people, leading an R&D team charged with developing next-generation training technologies and overseeing more than 350+ technicians supporting a wide variety of military aircraft. His most recent efforts have been in the area of leadership development and executive coaching, where he was involved with the development of Boeing’s emerging leaders, senior managers, and executives from around the globe. A life-long learner, Greg has a Ph.D. in Organization and Management with a specialization in Leadership. This served him well, as he was an adjunct professor with Embry-Riddle Aeronautical University for 8 years. In addition, he holds a Professional Certified Coach credential from the International Coach Federation. Greg has been active in small group ministries, including marketplace ministries in San Antonio and St. Louis for over 20 years. While in San Antonio, he was active in the Biblical Leadership for Excellence (BLE) ministry. Greg also served as a small group leader with Biblical Business Training (BBT) in St. Louis, leading a weekly bible study in Boeing’s defense headquarters. He is a deacon at the First Baptist Church of Wentzville and teaches Sunday School when needed. Greg has been married to his high school sweetheart, Nancy, for over 40 years. He enjoys fly fishing, reading, and anything that involves being outside with Nancy and their 14-year-old Siberian Husky.

“C12 is everything I was looking for and more of what I didn’t know I needed. My peers challenge me in my blind spots, love me in hard times, and encourage me to glorify God in the way I lead my team. It’s a home for business leaders.”

Brittany Zeller, founder and director of Tiny Feet Early Intervention / South Carolina C12 member
