With Zalgiris Kaunas, Hartenstein tasted his first major European success by winning the Lithuanian championship in 2017. That experience forged his versatility and tactical maturity.

Each stop enriched his game and confirmed his adaptability, a quality inherited from his cosmopolitan upbringing.
Alongside his club career, Hartenstein has honored his roots by representing the German national team. Married to model Kourtney Kellar and the father of a son, he has built personal stability despite the demands of professional sports. In Oklahoma City, this citizen of the world continues to write his story, armed with a unique international background in the NBA landscape.
