Christina Mathesius was born in 1969 in Heidelberg/ Germany and currently lives in Nashville/USA & Zug/Switzerland. She is an expert in marketing and sales, a business coach and trainer, as well as a keynote speaker. She has held a number of leading manager positions, including in international retail fashion. After the birth of her two children, she focused her attention on her family and supporting her husband's career. For this reason, the family moved from Dusseldorf to Switzerland. While abroad, she continued her career, among other things, as a lecturer for Marketing and Sales and went on to establish her own company, CM Marketing and Sales Consulting, in 2018. In the summer of that same year, she was initiated into the Senate of the Economy, and the family made the move to Nashville, Tennessee. Alongside her role as vice president of the Senate of the Economy USA, she continues to build up her consulting firm in Europe and in the US. In January of 2021, she was elected to the board of directors for the Sister Cities of Nashville and represents Nashville in its partner cities all over the world. In the summer of 2017, Christina received the diagnosis of breast cancer. Immediately following surgery and still during her radiation treatments, she began to train for a local half marathon. Since her three operations in less than one year, she has participated in five half marathons and, in the fall of 2020, successfully completed a 100-mile-challenge.
