The Effective Church
Group has been working
with churches for nearly
four decades.

Founded by Bill Easum in 1984, we’ve expanded with noted experts with hands-on experience in growing churches and coaching leaders to reach their potential. We’ve worked with churches from over 60 denominations including Non-Denominationals, Baptists, Methodists, Presbyterians, Disciples, Lutherans, American Baptist, Episcopalian, Seventh-day Adventists, and many more.

Because our mission is to equip churches to help every person become a follower of Jesus, we’ve intentionally devoted ourselves to creating supporting tools and resources for churches and church leaders. Combined, we’ve written over thirty books, written over 1000 articles and blog posts, and produced hundreds of training videos on nearly every aspect of what it takes to be a faithful and effective church in times like these.

Although we are called on to serve congregations and leaders in a variety of ways, most often we’re asked to help through on-site consultations, on-site congregational training, and one-on-one coaching.
