Born in, John M. Quincy earned a Bachelor of Science in Business Administration from Creighton University with a major in marketing and a concentration in finance. He subsequently received an MBA from DePaul University and moved to Minneapolis in 1994, where he worked as a marketing consultant. Quincy was the co-chair of Field Community School's parent-teacher association. He sought the DFL endorsement for a seat on the Minneapolis Board of Education in 2006, focusing on bringing the voices of parents to the Board. Ultimately, he was not endorsed. In 2009, Quincy vied for the DFL endorsement of his candidacy for a seat on the Minneapolis City Council representing the city's 11th Ward. Incumbent Scott Benson had announced plans to vacate his seat after his second term and Quincy won the DFL's endorsement, with 94% support at the April DFL convention. In August 2009, the Southside Pride predicted that Quincy "should have a walk against" his opponents during the general election. He defeated Gregg A. Iverson and David A. Alvarado in the first round of voting with 2,551 votes.
Minneapolis City Council
First term
Quincy was sworn in for his first term on January 4, 2010, along with two other new members to the council. He was appointed to head the Elections and Rules Committee. He also served on the Minneapolis–Saint Paul International Airport's Noise Oversight Committee. The Minneapolis City Council considered a plan to fund the U.S. Bank Stadium in 2012 which would circumvent a city charter requirement necessitating a public referendum for city funds in excess of $10 million to be spent on the construction of sports facilities. Quincy's stance on the issue was not known in February 2012, though he indicated support for the plan at that time for its building site and its predicted effect on property taxes. Ultimately, Quincy voted in favor of the plan to pay for the stadium with sales taxes once designated for the Minneapolis Convention Center. In 2013, Quincy ran for a second term on the City Council and sought the DFL endorsement once again, which he won unopposed. He won the election against Bob Schlosser and Matt Steele in the first round with 4,952 votes.
Second term
After his reelection, Quincy assumed the role of chair of the Ways and Means Committee, which handles the city's budget. In 2016, along with Minneapolis mayorBetsy Hodges, Quincy proposed a $300 million plan to improve the city's parks and roads over the next decade. Quincy ran for a third term in the 2017 City Council election and lost his seat to challenger Jeremy Schroeder. His term ended on January 8, 2018, when Schroeder was sworn into office.
Personal life
Quincy lived in Minneapolis's Page neighborhood as of 2006. His family consists of his wife Anne and two sons, Sam and Joe.
