Instead, Moncton Wildcats head coach, Ted Nolan, enticed him to come east and play in the Quebec Major Junior Hockey League (QMJHL), for the 2005–06 season.

The Wildcats couldn't be happier, as Marquardt improved and garnered more ice time as the season progressed, finishing with 25 points, 16 of which were goals.

[2] With the departure of several high-end prospects to a variety of AHL destinations, and coach Nolan to the National Hockey League (NHL), Marquardt had an unexpected surge in offensive production, in his second season with Moncton.

He would later be assigned to the Falcons' ECHL affiliates, the Stockton Thunder on March 23,[9] playing in 7 regular season contests, scoring one goal and tallying one assist.

[14] On September 2, 2014, after 6 seasons in the North American minor leagues, Marquardt pursued a career abroad in signing a one-year contract with German club, ESV Kaufbeuren of the DEL2.

[16] As a free agent the following season, Marquardt left for a second tenure abroad, signing a one-year deal with English-based EIHL club, the Coventry Blaze on July 13, 2016.

[18] After his departure from the Blaze, Marquardt stayed in the UK to sign for fellow Elite Ice Hockey League side Sheffield Steelers ahead of the 2017–18 season.

[21] Following the suspension of the 2020–21 Elite League season due to COVID-19 pandemic restrictions, Marquardt ended his four-year stay in the UK and returned to the ECHL to sign for Norfolk Admirals on September 24, 2020.

[23][24] Marquardt retired in 2021, taking up an assistant coach role with the Western Hockey League (WHL)'s Seattle Thunderbirds.
