As a junior Neuner skipped Team Germany in back-to-back years at the World Junior Championships, in 2007 and 2008. His teams finished 8th[2] and 6th,[3] respectively.
Later in the season the same team competed in the 2013 German Men's Curling Championship, though without Lang at skip. With Lang out, the rest of the team was promoted a position, with Herberg skipping, Messenzehl as third, Neuner as second, and former alternate Kempf as lead. The team finished with a 4-2 record, good enough for the silver medal behind John Jahr.[5] The next year Neuner returned to the German Championship with a different team, throwing third for skip Konstantin Kampf. Despite the different team, the result was the same for Neuner, another silver medal to John Jahr's gold.[6]
For the 2018 European Championships Neuner played as second for skip Marc Muskatewitz. The team just missed getting a medal, losing the bronze medal match to Italy's Joël Retornaz 6-8.[7] Later in the same season Neuner played with Muskatewitz again, this time as third at the 2019 World Men's Championship.[8][9] It was Neuner's first World Men's Championship and they finished in 8th place, Germany's best finish since 2014.[10]
Personal life
Neuner started curling around the age of 15. He attended LMU Munich.[11]
