Rev Chris Menzfeld

Regional Representative - South West England and South Wales

Chris had a Roman Catholic upbringing owing to the fact that his father was Polish. He travelled to Eastern Europe many times, especially during the early days of communism, and well remembers the border crossings and ‘Cold War’ atmosphere that gripped the east. Conversion came in his late teens, and he was greatly affected by the love of God’s people, as well as the winsome and effective preaching of the Revd. Frank Goodwin.

After training in electrical engineering, he joined the family business in 1982. In the course of time he received a call from the Lord to preach the Word. He trained at the London Theological Seminary, and in 1994 became pastor of Hitcham Free Church. He ministered there until 2009 before joining SGA.
