In 2005, after playing college basketball at Northwestern University in Illinois, Parker came back to France, and he suited up for the Paris Basket Racing club.

On November 19, 2006, he scored a career-high 23 points, on 7-for-11 shooting from 3-point range, in an 83–77 win over Pau-Orthez.

After his short playing career, Parker decided to become an assistant coach with the French club ASVEL, in 2013.

In January 2018, he became the club's interim head coach, after J. D. Jackson was fired from the position.

T. J. Parker is the younger brother of Tony Parker, who is the President of the French basketball club ASVEL, and a former basketball player of the NBA clubs the San Antonio Spurs and the Charlotte Hornets.
