President (Volunteer)

Midlens Photo Club

Middelburg Area, South Africa

I have been a member of the Middelburg Camera Club since 1998 when my wife and I started with photography as a serious hobby. I have realised that the club environment facilitated knowledge sharing and in so doing I have learned much. I served in various capacities on the management committee for the club. In life I have realised that by giving you will be increasing that which you have received. I am still a member of the club although I have felt that young blood is needed in the management and guidance.
