Greg was called to missions at a young age and responded by joining TWR in 1995 after completing an electronics technician program at SAIT. Greg grew up in Calgary, Alberta, and attended First Alliance Church. After joining TWR, Greg worked for many years as a studio technician in Bonaire, Slovakia and South Africa.
Ingrid was born and raised in Port Elizabeth, South Africa. She moved to Johannesburg in 1999 and was working for a freight company as an accountant when she received her call into missions. Ingrid was involved in the young adult ministry at Edenvale Baptist Church in Johannesburg, and that is where she met Greg.
The Clarkes were married in South Africa in 2005 and continued to serve with TWR. At the end of 2013, the Clarkes moved to Swaziland, now called Eswatini, where Greg took on the role of system administrator at the Swaziland Transmitter Station. Greg is now the station director, and Ingrid uses her skills as the finance manager for the Eswatini office.
Greg and Ingrid have two children, Rebekah and Caleb.
