  • “Just wanted to say that it was a real pleasure working with Rachel last night at Wembley. She was on the ball and followed the brief perfectly, working hard over the entire evening. Rachel was a natural on stage and added great charisma and humour to the quiz delivery. I look forward to the opportunity to work with her again hopefully in the future.”



    “Having worked with a lot of celebrities over the years I found Rachel to be one of the best. She spent a great deal of time reading and discussing the briefing notes beforehand and made sure she fully understood what we wanted. She thoroughly embraced the project and delivered exactly what was asked. She was also an absolute delight, friendly, down to earth and utterly professional.  Rachel was interviewing teachers at an awards ceremony and spent the day, completely unscripted, engaging with all sorts of personalities consistently getting the responses we needed whilst ensuring the teachers really enjoyed the experience ,  I can assure you this was no mean feat. I would l have absolutely no hesitation in recommending Rachel.”
