It is certainly no coincidence that Marion has ended up becoming a profile for BMS Herlev. He is a real BMS Herlev boy and has played in the club all his life. His mother, Nanna Mitrovic Marion, makes a big effort at the club. In general, Marion was brought up in a real basketball family. His father, Tony Marion, came to Denmark in 1994, and played for several years in Holbæk and Næstved. Nanna Marion was also an elite basketball player in Denmark and has been player of the year in the Women's Basketball League.
