In 2009, he signed with the Florida Panthers and spent the subsequent season between the NHL and the team's AHL affiliate, the Rochester Americans.

The following off-season, he was traded to the Canucks, joining the team in 2011 on their run to the Stanley Cup Finals, where they lost to the Boston Bruins.

[4] While playing college hockey with the Notre Dame Fighting Irish, he studied finance before dropping out to join the Kitchener Rangers.

He later re-enrolled at University of Notre Dame during his two-year hiatus from his hockey career, to complete his finance degree.

[5] After his playing career ended Oreskovich spent two years working at Sun Life Financial, moving into a management position.

With aspirations to turn professional sooner, he left Notre Dame nine games into his sophomore year to join the OHL, where his major junior rights had been traded on November 24, 2005, from Windsor to the Kitchener Rangers.

[4][11] Kitchener was Oreskovich's desired destination to play major junior, as his best friend and former minor hockey teammate Evan McGrath starred with the Rangers.

[13] He returned for his second Avalanche training camp for the 2007–08 season and was assigned to their American Hockey League (AHL) affiliate, the Lake Erie Monsters.

Oreskovich, however, did not report to the Monsters; he was suspended by the Avalanche, before announcing his retirement from the game, citing burnout and a lost drive, and re-enrolled at Notre Dame.

[17] Providing an energetic checking presence with the Panthers, he scored his first NHL goal against Jonathan Quick of the Los Angeles Kings in a 4–3 defeat on November 16.

[25] He appeared in one game during the call-up before being sent back down, with Canucks head coach Alain Vigneault suggesting he did not play physical enough.
