The first time she sat on a horse was even before Stefanie was able to walk. At the age of 10 she started with professional riding lessons and soon was fascinated by the discipline of reining. In 2008 she got her first own horse, a Freiberger (swiss breed) gelding named Coquin, which she showed successfully in all-around and NRHA shows. Since the foundation in 2015, Stefanie has been part of the Swiss young rider reining team. In the beginning of 2017 she had to leave the young riders team because of her age. As soon as Snap turns 7 years in 2018, the team will try to get their qualifications in FEI CRI 3* events to become a part of the Swiss senior team.
