With 311 caps, Pearce is also the second-most capped player, male or female, in U.S. and world history, after Kristine Lilly. Pearce played for Central Jersey Splash and New Jersey Lady Stallions, in 1997 and 1998 respectively, of the W-League.

In 2002, Christie bounced back to play in 1699 minutes over 19 games, and another 18 games in 2003 in addition to her national team duties. Shortly after concluding its third season, the WUSA suspended all operations. In anticipation of an eventual relaunch, WUSA preserved its rights in the team names, logos and similar properties. The next attempt at women's professional soccer in the United States kicked off in 2008 under the name of Women's Professional Soccer. On September 16, 2008, the initial WPS player allocation was conducted and Pearce was chosen as captain for New Jersey's Sky Blue FC with fellow US Women's National Team players Heather O'Reilly and Natasha Kai. In its inaugural season, Pearce and Sky Blue FC struggled, including the suspension of their first head coach Ian Sawyers and the resignation of his successor, Kelly Lindsey. In July 2009, the Sky Blue organization announced that Pearce would serve as the caretaker coach, in addition to her playing duties, for the remainder of the WPS season. After taking on the position as head coach, the third in one season for Sky Blue FC, Pearce took her team on to win the 2009 Women's Professional Soccer Playoffs. It was later revealed she was almost three months pregnant with her second child at the time of the match. One week later, she was named WPS Sportswoman of the Year. She remained with Sky Blue in a playing role for 2010 before switching to magicJack ahead of the 2011 Women's Professional Soccer. On January 11, 2013 Pearce was one of three members from the United States women's national team that was allocated to the new NWSL club Sky Blue FC, along with Jillian Loyden and Kelley O'Hara.
