Girsh graduated from the University of Notre Dame with a bachelor of science in mathematics in 1998 and the University of Chicago Booth School of Business with a Master of Business Administration in 2003. He worked in valuations for Boston Consulting Group in Chicago.
In 2005, wanting to pursue a career in Major League Baseball (MLB), Girsch wrote an academic paper on the valuation of MLB draft picks and sent it to teams. John Mozeliak, the general manager of the St. Louis Cardinals, responded and hired him in 2006 as the coordinator for amateur scouting. He was promoted to director of baseball development in 2008 and to assistant general manager in 2011. In 2017, the Cardinals promoted Mozeliak to the newly created position of President of Baseball Operations and promoted Girsch to general manager. As General Manager, he was responsible in signing Paul DeJong, Paul Goldschmidt, and Matt Carpenter to contract extensions.
