Fiona started her career working for Central Government before realising that she was destined to work outdoors. She started volunteering with the youth club at Stepney City Farm and after 2 years moving into, and then out of, mainstream secondary teaching, she began running environmental education workshops at Stepney City Farm. Currently she runs a gardening project for adults with mental health needs at Mudchute City Farm, a gardening group for Bangladeshi women in Whitechapel, and tutors looked-after children in maths. She is also trying to set up a community animal farm in Brixton.

Fiona was awarded LEEF Fellowship on 12 July 2016 at the Royal Parks Foundation Education Centre, Hyde Park.
