He and his wife, Melody, have five children, three still at home.

Gary Diehl, Consultant/Coach

Assuming a broad array of lay leadership responsibilities in his home church for the last twenty years has given Gary a hands-on perspective of many ministry functions within the church. With a career in business and a passion to teach God's Word, Gary is a frequent speaker for churches, business gatherings, leadership and youth retreats, men's groups, and civic organizations.

A formative ministry experience was working with his congregation's Vision Team as they wrestled with questions about growth, health, buildings, and what God wanted for the church. Gary was introduced to the practical principles of When Not to Build as he served as his church's coordinator for a Living Stones consultation in 1998.

Gary began consulting with churches in 2001 out of a growing conviction that many churches need wise, comprehensive, biblical counsel to become healthy and relevant in the 21st century. He and his wife Nancy live in Alliance, Ohio. They have four children and two grandchildren.
