Nik Hartley OBE
chief executive
Until he joined SIA in 2019, Nik had worked his whole life in the humanitarian field across Africa, the Caribbean, South America and South Asia. International development is Nik’s passion. He helped to build an award-winning global model enabling young people to lead humanitarian efforts in their own nations. That even led to 2,000 young Sierra Leoneans gaining expert frontline roles to tackle the Ebola Crisis in 2014-16. Nik lives a breezy 35-minute bike ride from our HQ in Milton Keynes. When not attending to his two children, you’ll often see him watch the topsy-turvy fortunes of his beloved Stoke City FC. On the last count Nik has lived in, worked in or visited 74 countries.
