Mac has been at IBC since 1968 when he came along with other students studying at Portsmouth Polytechnic. He became a Christian in his early teens and was a member of a Brethren Chapel until moving to Portsmouth. He is married to Wendy and they have two children, Joanne and Richard, both of whom now have their own families. He spent most of his working life teaching music and French. Mac has many interests but music – in its many forms – is probably his greatest love.
