Spreadsheets and budgets, and just a little bit of wonkiness.

Actual job
Helping put other people's fabulous ideas into action by liaising with the Solar Schools, our partners, using my phone voice a lot. 

Having undergone a premature mid-life crisis, Amy veered wildly away from veterinary medicine straight into the welcoming arms of a Lighter Later internship. A big fan of 10:10 since its launch, she managed to forge a CV of call centres, waitressing and a short stint at Chester zoo into exactly what you need for a career in campaigning.

Leo Murray

Leo MurrayJob title
Campaign manager, positive investment

Actual job
Leo heads up the development of 10:10's new community energy campaigns, launching in 2014.

Leo's professional background is in animation, but after becoming obsessed with climate change in 2005 he decided he couldn't really make adverts any more and took up semi-professional trouble-making in the climate struggle.

Luckily Franny Armstrong came along and invited Leo to work as an animator on the Age of Stupid, a role which inexorably morphed into the design and early implementation of 10:10. After a long hiatus to help grow two small children, Leo is back at his desk at 10:10 working part-time on the Back Balcombe project.

Esther Barlow

Job title
Campaigns assistant

After realising that studying History at uni doesn't really lead to an obvious career path, Esther turned her attention to saving the planet. She started as a comms intern, and now spends most of her time playing with photos and wesbites.
