I was in health care with Altrecht Utrecht (2010 - 2017) and they learned about my Excel knowledge so I helped the administration there with some Excels. I even helped my SPV’er with some computer problems in Excel or Word. I don’t remember exactly which one.
When my father (1945-2011) died and my contract at VUMC ended I helped my psychologist with SPSS for his research for his dissertation. This was brief but fun. It stopped when I started working at CBS and he could get his SPSS done at the university.
It was fun getting to know my aid workers in another way as a volunteer and that I could help them. Afterwards I stayed in mental health care there till 2017.
