As a hobby I am a qualified swimming instructor who is giving swimming lessons to children aged 4-16 as volunteer work. I have a wide range of swimming diplomas myself, and did these instructor courses:
| 2006 | Zwemleider B |
| 1998 | Zwemleider A |
| 1994 | Assistent Zwemleider (deprecated) |
I am a member of swimming club Watervrienden Geleen where I am also responsible for the website and the club magazine.
