Brittany Bock grew up in Illinois lacing her cleats up as a child for Hudson Fortune in the Team Chicago Soccer Club. She also spent time playing for the Windy City Pride and Eclipse Select. Her sister also played soccer and the two of them played together and won the National 3v3 Soccer Tournament in 2002.

Bock played college soccer at the University of Notre Dame from 2005-2008. She scored 121 points in her time there with 46 goals and 29 assists. She was a Hermann trophy finalist her senior year after a strong season that included 17 starts, 6 goals and 9 assists. Through out her college tenure her awards included being the co-recipient of the BIG EAST's Offensive Player of the Year award, multiple BIG EAST Player of the Week and First Team honors.

Bock was the fifth overall selection in the 2009 WPS draft taken by the Los Angeles Sol where she scored 2 goals in 19 games. While with the Sol she played all over the field including center back. The team collapsed after a year and she was then taken by the Washington Freedom during a Dispersal Draft of Sol players. She played in 14 games for the Freedom before signing with the Western New York Flash. Bock scored just a single goal that season but the team was able to win the WPS Championship title that year. The WPS folded after the 2011 season and Bock chose to sign with the Colorado Rush who competed in the W-League. There she played 12 games netting 4 goals during the 2012 season. 2013 saw the creation of the National Women's Soccer League and Bock signed with Sky Blue FC. Unfortunately, she spent much of the season battling injuries and had only 5 starts.

She has not earned a cap with the USWNT senior team but was an active member of the Youth National teams. She started four games as a center midfielder in the 2006 FIFA U-20 Women's World Championship. She had 14 caps and three goals during her time with the U-20s. She was also a part of the U-19s and U-16s the latter of which she captained in 2003.

A versatile player who excels all over the field her biggest strength lays in the midfield. Once the ball is at her feet good luck knocking her off of it and if you are the one with the ball she has no problem making the tackle to get you off the ball. A strong dribbler she also has a laser like quality to her passes with the ability to shoot off either foot. A strong target player she dominates the ball in the air with no problem heading the ball in to the back of the net. With her college coach at the helm Bock should have no problem finding her footing in Houston as the back bone of the midfield.
