The following off-season, on July 7, 2007, Oreskovich was signed to a two-year, entry level contract by the Colorado Avalanche.
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.

After a two-year hiatus, Oreskovich regained ambitions to play professionally and reached out to former Kitchener Rangers coach Peter DeBoer, now head coach of the NHL's Florida Panthers.
He earned a try-out with the Panthers at their training camp for the 2009–10 season.
He was assigned to Florida's AHL affiliate, the Rochester Americans and was signed to a two-year contract with the Panthers on October 7, 2009.
Within less than a month, Oreskovich was called up to the NHL, making his debut with the Panthers against the St. Louis Blues on October 31.
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.
He split his professional rookie season between the Panthers and Americans, scoring six points over 50 games in the NHL and 15 points over 34 games in the AHL.

During the 2010 NHL Entry Draft on June 25, 2010, Oreskovich was traded to the Vancouver Canucks along with defenceman Keith Ballard in exchange for Michael Grabner, Steve Bernier, and Vancouver's first round pick, the 25th overall selection, used to select Quinton Howden.
Following the pre-season, the Canucks assigned Oreskovich to their AHL affiliate the Manitoba Moose.
Shortly after returning from a shoulder injury that sidelined him for 15 games, he was recalled by the Canucks on February 10, 2011.
After making his Canucks debut two nights later against the Calgary Flames, he spent the remainder of the regular season being assigned back-and-forth from the Canucks and Moose, recording 3 assists over 16 NHL games and 12 points (4 goals and 8 assists) over 40 AHL games.
Oreskovich remained with the Canucks for the entire 2011 playoffs.
He played in 19 games, not recording any points, as the Canucks lost in the Stanley Cup Finals to the Boston Bruins.

During the off-season, Oreskovich became a restricted free agent on July 1, 2011.
Without arbitration rights (due to his lack of experience in the league), negotiations with Vancouver continued through the summer.
As training camp neared, Oreskovich agreed on a one-year, two-way contract worth $605,000 in the NHL and $105,000 in the minors.
Prior to the start of the season he was waived by Vancouver after the team traded for Dale Weise from the New York Rangers.
After clearing waivers, he was assigned to the Canucks' new AHL affiliate, the Chicago Wolves on October 5, 2011.
Returning to the AHL, he suffered a concussion that sidelined him for several games.
Following his recovery, he was called up to the Canucks on December 5, 2011, to replace injured winger Chris Higgins.
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.
Oreskovich retired at the end of the season, citing injury concerns.
