In 2016 Martyn Cooper undertook a 50 hours consultancy to The Paciello Group (https://www.paciellogroup.com/), authoring an e-learning module on Maths Accessibility, for one of their major clients. Here is a testimonial he received following that work:
“Martyn was a diligent and thoughtful author, and exhibited strong domain knowledge as well as a high level of sensitivity to the technical and social challenges that digital accessibility attempts to address.” [David Sloan, The Paciello Group]
