Quinlan began racing go-karts at the age of five, and then raced in the
ARCA/CRA Super Series, and his successes racing in that series earned him a part-time ride in the K&N Pro Series East with the new Rette Jones Racing No. 30 team in
2015. His first race was at
Columbus Motor Speedway, where he surprisingly finished second in his and the team's debut in the series. Quinlan also started third and led 63 laps in that race. He would run two more races that year, coming at
New Hampshire and
Richmond. With
Dominique Van Wieringen in the No. 30 full-time in
2016, Quinlan drove the team's second car, the No. 29, at
Stafford. He made one other start that year, driving the No. 02 for
Young's Motorsports at
Iowa. He finished eighteenth in both of his races in 2016. His only start of 2017 came at the road course of
New Jersey Motorsports Park, finishing eighth driving the No. 28 for RJR. For 2018, Rette Jones put Quinlan in their ARCA Racing Series car at Daytona. In the race, Quinlan crashed out and finished 37th. On the K&N side, he ran six of the first seven races of the season in the Rette Jones No. 30 with a best finish of fourth at NJMP. For his second ARCA start, Quinlan returned to the same race and team the following year, where he picked up an impressive third place finish. After his strong run at Daytona, Quinlan and RJR returned to run Talladega, where they would finish ninth. ==Personal life==
