Frederik has been employed at Kiropraktik i Centrum since December 2020. In addition, he has his own clinic / training center in Gentofte Badminton Club "Performancecenter.dk". Here, Frederik treats many professional and semi-professional badminton players in collaboration with Peter Gade. From here, Frederik also has extensive experience with tennis and golf players, and he himself is a former elite golfer. In addition to elite athletes, Frederik also works with ordinary exercisers. "My long-term goal in the performance center is to be able to extend an athlete's "lifetime" with his sport, so I am someone you seek out if you want your body to last a few years longer at the end of your career."
Frederik lives in Hørsholm and is married to Camilla. Together they have two children, August from 2014 and Esther from 2018.
