Evangelism
The Hamm Family Ministries is prepared and experienced in Evangelistic Crusades.
We have a long history in this particular ministry. Beginning at age 10, Dr. Ron Hamm was involved in Crusade Evangelism/Revival Ministry, as a musician and singer. This experience began a lifelong love of winning the lost to Christ. The Drs. Hamm, and two other young men, Gary Buckles and Jim Brinkley, began the World Challenge Singers in the early 1970s and traveled in Crusade Evangelism for many years. The World Challenge Singers are still available even now to carry on this ministry as requested. Visit and like our page at Facebook. WCS would love to come to your church for a time of “Old Fashioned Gospel Music.”
As the sons, Regie and Leny, grew into musicians, the Hamm Family Ministry continued with the ministry of Evangelism and traveled extensively throughout the US. Night after night, all across America and Canada, this family group ministered to the masses and were instrumental in thousands coming to Christ. 
The Hamms continue to minister in churches where ever they are invited. Please see our contact information for availability. We would be honored to come and bring hope to your area.
