Jeg er ansat som adjunkt på læreruddannelsen i Jelling, hvor jeg underviser i matematik. Jeg har tidligere været pædagogisk konsulent i matematik og tysk hos UCL ved Center for Undervisningsmidler (CFU) in Vejle and Odense. Jeg har også været lærer i udskolingen (7.-9. klasse) på Lyshøjskolen i Kolding. Jeg ejer og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
