About us Our people Trustees Jon Sparkes Jon is Chief Executive of the charity Crisis. He was previously Chief Executive at Scope and Chief Operating Officer at Unicef UK. His early background was in HR and he has held a number of HR Director positions in both the commercial and public sectors. Jon sits on the Services and Quality Committee. "I joined the Board of SeeAbility after a number of years leading the disability charity Scope. During that time I saw the extent to which disabled people are excluded from society and wanted to keep doing something about that. SeeAbility is the most progressive organisation working with and for disabled people with sight impairment, one of the most excluded groups in society. I hope as a Trustee to be contributing to developing SeeAbility as a service provider and campaigner for this group."
