Player Bio

Daniel Theis was born in Salzgitter, Germany, in 1992. As a youth, Theis was more interested in soccer than basketball. His father and older brother Frank convinced Daniel to focus on basketball. Frank and Daniel would eventually play hoops professionally together. As an 18-year-old, Daniel played his first of two seasons with Braunschweig's youth development squad, where he played side-by-side with Frank. A knee injury forced Frank to quit basketball (he is now a middle school teacher). Daniel is a three-time German National Champion, with all three titles coming while he played for Brose Bamberg. Theis and his family supports the charity Room To Grow, which helps underserved parents by offering them essential resources needed to raise children.
