The news comes just hours after she qualified for the 2018 Winter Olympic Games in Pyeongchang after solid World Cup results in Maribor, Slovenia and Falchau, Austria.
Charlie has battled her way back to the top after a career threatening crash on the slopes in late 2014 left her with four broken vertebrae. Her commitment and fighting spirit saw her return to the slopes a mere six weeks after the accident. In an 18 month journey back to full fitness, she was crowned British Ladies National Slalom Champion after a triumphant win at the Delancey British National Alpine Ski Championships in 2016.
Managing Director Michael Pettifer says: "We are absolutely delighted to welcome Charlie to the MPI team. "It is a huge privilege to be working with an athelete who has a strong chance of a place in next year's Team GBR."
