I hired Katherine for a very demanding and intense week of activity in Argentina, ranging from small workshops to a plenary session in a major national conference for an audience over 800 strong. Each and every one of those sessions was a success, built on three cornerstones: her knowledge and experience of materials design and language teaching, her excellent session design, and her warmth and professionalism in the delivery. She connected with every single person in those audiences, left nothing but smiles, insights and rave reviews in her wake, and was a delight to work with. I would hire her again in a heartbeat.
