'Leonie was a senior UX designer in one of my teams at KPN. She excels where UX strategy and UX execution meet. She combines a data-driven approach to UX design with a commitment to (commercial) results and mastery of online persuasion. A team player that does not mind putting in extra efforts to get the job done.'

'I had the pleasure of working with Leonie for about three years, of which about two as a manager at Telfort. Working with Leonie always guaranteed a weekly influx of new ideas, insights, deep-dives into our consumers' psychology, and new converting designs. I would sometimes compare 1-on-1's with Leonie to a personal TED-talk, they were always filled with many brainstorms about our (e-commerce) website, UX work in general, consumer psychology or just design thinking/process. Truly fun, and inspiring'
