'Making Work Enjoyable for Children' I’ve spent 17 years in retail, gaining experience in sales, customer service, training, HR, and recruitment. This taught me that business growth relies on people’s growth, inspiring me to pursue my own and motivate children.

Head of Learning Tech

I love both learning and technology, so leading Impact’s learning tech R&D is a fantastic gig. Technology can sometimes feel in conflict with the humanity we seek to serve, but thoughtful application of tech immerses us in challenging experiences, brings us closer together and helps us to learn the most important, most human skills. My approach to learning tech (and life, for that matter) echoes Impact’s practice: experiential and human-centred.
