Keir and Callie were born in Harare, Zimbabwe. They married in 1974.
They are based in Cornerstone Church in Bedfordview Johannedburg.
Keir qualified in Medical and Veterinary Technology (Histopathology and Bacteriology). He also served in the military for 14 yrs, and volunteered for service in a Special Forces unit in Rhodesia. He was wounded in both legs and cried out to God for mercy for his life. God answered with an Acts 9:3 experience: “… a light shone around him from heaven.” Whilst recovering from the wound he studied Medicine at the University of Rhodesia. They felt the call to full time ministry, and so he gave up medicine, and were obedient to God.
1980-1982 Keir and Callie, with their two small children, relocated to Dallas, Texas, USA where they enrolled at a bible college called Christ for the Nations Bible Institute (CFNI).
