Conroy played in the 2006–07 NBA preseason with the Charlotte Bobcats, but he was cut before the NBA regular season started. He then signed with the Tulsa 66ers of the NBA D-League. On January 30, 2007, Conroy was signed to a ten-day contract by the Memphis Grizzlies after they had opened up a roster spot by waiving guard Eddie Jones. After his contract ended, Conroy returned to the 66ers. On February 28, 2007, Conroy was signed to another ten-day contract by the Los Angeles Clippers, following point guard Shaun Livingston's season-ending knee injury. The team waived Von Wafer to make room on their roster for Conroy. However, after averaging two assists in four games played, he was waived. On April 6, he was re-signed by the Clippers, who made room on their roster by waiving Željko Rebrača. Conroy then played in the Italian league with both Virtus Bologna and Olimpia Milano and in the Euroleague with Virtus Bologna, where he averaged 7.8 points and 3.2 assists per game during the 2007–08 season. He then played with the NBA D-League clubs the Albuquerque Thunderbirds and the Rio Grande Valley Vipers. In 2009, he tied Morris Almond's D-League single-game record with 53 points, but this was surpassed by Pierre Jackson in 2014. He was called up by the Houston Rockets from the Vipers on January 29, 2010 on a 10-day contract, and returned to the Vipers when the contract expired on February 8. Conroy was again recalled by the Rockets on March 2, 2010, and sent back to the Vipers on March 11, 2010. In January 2011 he signed with Oyak Renault in Bursa, Turkey. In January 2012, he rejoined the Rio Grande Valley Vipers. In September 2012, Conroy signed with the Minnesota Timberwolves. He was waived on November 15, 2012, after appearing in four games. Despite being waived, Conroy remained with the Timberwolves that season as a member of their scouting staff. It was reported that he was not retiring from his playing career, but merely putting it on hold. In December 2013, he signed with Medi Bayreuth. In February 2014 his contract was not extended and he left the team. Instead Conroy decided to sign with the German team SC Rasta Vechta for the remainder of the season.
