I was an associate for Impact for 21 years before becoming part of the full-time team. I love the sense of fun, friendship, camaraderie and the way Impact works. Oh, by the way I’m on the Technical Support Team – ropes and boats, programme design and logistics and lots of other things too. I love my job, get loads of out of it, meet lots of amazing people and learn new things all the time – how lucky am I?
