Quarterley's NASCAR career started in 1994, when he began competing in what was then known as the NASCAR Busch North Series.
He entered his own car in a race at Lime Rock Park, finishing 12th.

Quarterley continued making sporadic Busch North starts before running the full season for the first time in 2001.
He scored his first win at Beech Ridge Motor Speedway, leading all but two laps.
In 2002, Quarterley nearly won at Watkins Glen International, winning the pole and leading the most laps.
However, he ran out of fuel during a green-white-checker finish.

Quarterley eventually scaled back to a part-time schedule.
Despite originally announcing plans to run the West Series race at Sonoma, he sat out the entire 2007 season.
During the season, he served as crew chief for John Salemi.

In 2008, Quarterley drove two road course races on back-to-back weekends in the renamed Nationwide Series for Mike Harmon Racing.
He finished 42nd and 41st at Circuit Gilles Villeneuve and Watkins Glen respectively.

Quarterley's 2011 season was highlighted by a second-place finish at Dover International Speedway.
He was later fined, however, for a shock absorber violation on his car.

In 2018, Quarterley returned to the K&N Pro Series East after a two-year absence to compete for NextGen Motorsports in the JustDrive.com 125.
He qualified 15th and finished 13th, dropping out after 43 laps with rear end problems on the car.
