It was a great experience for myself and the rest of the Unpacked team to work with you in Berlin. Your insights, passion and undefeatable positive attitude were critical in the execution of Samsung's latest product presentation...the opportunity you have as a role model, to guide youth towards science and technology, is fantastic and so important...

Rachel was absolutely fantastic, a lovely lady and pleasure to work with. With her support and promotion of STEM is the perfect fit for the Women in Rail Awards. Her engagement with guests after the presentations was brilliant - and there were a lot of smiley faces in the room as she took the time to pose for photos with guests.
