Kevin Vaughn with his wife Sheila lives in St Albans in the UK. They have three children, all of whom are married. He has been involved in the medical ministry since he was a child, since his father was a medical missionary.
His medical studies and work took him to various parts of the world such as India, East Africa, and Uganda before moving to the UK. It was here his work with the CMF UK led him to get involved with ICMDA particularly the Eurasia region. Now he is serving on the board and is involved with the global mission of ICMDA
