Ps. Steve is the small groups pastor at Saddleback church. He has written three books, all on small groups. Check out the links below:

Small Groups with Purpose
Leading Small Groups with Purpose
Planning Small Groups with Purpose

In addition to writing and leading in ministry, Ps. Steve also founded the Small Group Network which is a place for small group pastors and leaders to connect with other like minded ministry people to share resources and encouragement.

I had a great conversation with Ps. Steve and I know you will be encouraged through his testimony, and his explanation of the small group culture at Saddleback Church.
