Our Team

Living Stones Associates is a network of independent consultants/coaches guided by a common vision, who work together to help churches become healthier and increase ministry effectiveness.

Ray Bowman, Founder

After thirty years as an architect, designing various kinds of buildings including church buildings, Ray Bowman left his architectural firm in 1980 to begin a ministry of consulting with churches.  (Read the story in chapter 1 of When Not to Build.)  Over the next few years, Ray used his architectural expertise to help churches avoid unnecessary building.  Learning from each church he worked with, within a few years Ray had learned how to help most churches make their buildings work well for a congregation two to three times the size for which it had been originally designed.  By applying Ray's approach, growing churches were able to get out of debt and stay out of debt, even through major building programs.

His articles have appeared in more than 40 periodicals including Leadership, Your Church, Ministries Today, and Clergy Journal.  He is coauthor with Eddy Hall of When Not to Build.

Now semi-retired, Ray continues to mentor the other members of the consulting team he founded and to collaborate with them on consultations from his studio in Olathe, Kansas.

With ministry experience that includes directing an inner city ministry, youth ministry, extensive writing and editing, denominational staff ministry, and more than 25 years in small group ministry, Eddy began working with Ray Bowman in 1986, collaborating with Ray on all his articles and books.  In 1996, Eddy joined the consulting team and now devotes full-time to consulting with churches.

In addition to coauthoring When Not to Build, Eddy has also coauthored When There's No Burning Bush and other books.  His articles have appeared in about 120 periodicals including Leadership, Guideposts, Campus Life, and Focus on the Family Magazine.

Eddy leads the team in carrying on Ray's pioneering work in facility utilization and planning. Drawing on his training (a degree in Christian education) and 30 years of varied ministry leadership experience, Eddy has greatly expanded the services the team offers in strategic ministry planning, enhancing church health, and coaching professional and lay leaders.  He lives in Goessel, Kansas.

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.
