He finished the season earning American Hockey Coaches Association (AHCA) All-Hockey East Teams First Team honors and earned both Hockey East Best Defensive Defenseman honor and the Bob Monahan Award as the top defenseman in New England. During the 2011 offseason, Dumoulin attended the Hurricanes Conditioning Camp. Upon returning to the Eagles for the 2011–12 season, Dumoulin tallied seven goals and 28 points through 44 games as the Eagles qualified for the 2012 NCAA Frozen Four. During the Final against Ferris State, Dumoulin tallied a goal in the first period to help lead the team to a 4–1 win. Prior to the tournament, Dumoulin was named a finalist for the 2012 Hobey Baker Award as he led all Hockey East defensemen in scoring. Following the Eagles' NCAA win, Dumoulin was again selected for the All-Tournament Team alongside teammates Johnny Gaudreau and Parker Milner. On April 10, 2012, the Hurricanes signed Dumoulin to an entry-level contract. However, a few months later on June 22, 2012, Dumoulin was traded to the Pittsburgh Penguins, along with Brandon Sutter and the 8th overall selection (Derrick Pouliot) in the 2012 NHL Entry Draft, for center Jordan Staal. Professional Upon concluding his collegiate career, Dumoulin attended the Penguins' annual Development Camp. After attending the camp, Dumoulin was re-assigned to their American Hockey League (AHL) affiliate, the Wilkes-Barre/Scranton Penguins, to begin the 2012–13 season. In his first season with the WBS Penguins, Dumoulin tallied six goals and 18 assists for 24 points through 79 games. The following season, Dumoulin again began with the WBS Penguins before being recalled on December 9, 2013. At the time, he had tallied six points in 22 games. He subsequently made his NHL debut in a December 14, game against the Detroit Red Wings. As a result of numerous penalties taken during the game, Dumoulin played 18:10 minutes of ice time. He scored his first NHL point, an assist on Chris Conner's goal, in a game two days later against netminder Jonathan Bernier of the Toronto Maple Leafs. He was re-assigned to the AHL after recording one assist in six games. Dumoulin rejoined the WBS Penguins for their 2014 Calder Cup playoffs run and recorded 12 points through 17 games.
