After the 2008 season, he ended his competitive playing sports career in Schwäbisch Hall and shifted completely to his coaching duties.
In 2009 and 2010, Neuman coordinated the offensive play of the Schwäbisch Hall Unicorns as a member of the coaching staff, and from 2011 to 2013 he served in the same capacity for the Vienna Vikings.
Neuman, whose wife is from Schwäbisch Hall, led the team to win the German championship in 2017 and 2018 after the "Unicorns" had finished second in each of the previous three years.
In contrast, Neuman achieved his first international success as head coach with the Unicorns in 2021, winning the Central European Football League (CEFL).
In addition to his role as head coach of the Schwäbisch Hall Unicorns, Neuman also took charge of the club's youth academy.
