Sini was born on March 17, 1973 in Prijedor, Northwest Bosnia & Herzegovina. As a youth he was often seen playing with a soccer ball and developing skills on the pitch. Ultimately he made the ball his best friend!

He joined the youth programs in 3rd Former Yugoslavia Division to further his development. At 17, he was offered his first professional contract for FK-RUDAR that played in 2nd Former Yugoslavia League.

In 1992 he joined 3rd Division SC Norderstedt in Germany and reached qualifiers for 2nd Bundesciga. His time playing for Germany from 1992 – 1997 gained him experience and understanding of the multi-faceted aspects of soccer.

In 1997 he immigrated to Edmonton, Alberta. Where he quickly fell in love with the culture, people and country.

After playing for almost 12 years in Canada, an opportunity came for a new challenge with teaching the skills and principles he acquired to youth soccer players. This opportunity has allowed him to bring his passion and love for the world’s most popular game.
