Greisinger graduated from McLean High School in Virginia, then played his college ball at the University of Virginia.
He played for the Detroit Tigers, Minnesota Twins, and Atlanta Braves. Greisinger missed nearly 4 seasons from 1998 to 2002 with arm ligament injuries. He was a non-roster invitee to spring training with the Washington Nationals in 2005; he was sent to the Braves as part of a conditional deal. After being released by the Braves on June 7, 2005, Greisinger played for the Kia Tigers of the KBO in 2006, going 14–12 with a 3.09 ERA in 29 games.
Greisinger became the ace for the Tokyo Yakult Swallows in the Central League in Japan for the 2007 season, but Yakult's low budget led to them being forced to release both Greisinger and outfielder Alex Ramirez. Greisinger signed with the Yomiuri Giants for the 2008 season and led the Central League in wins with 17. In 2009, Greisinger went 13–6 with a 3.47 ERA, but missed time near the end of the season due to inflammation in his right (pitching) elbow. He did not pitch at all in the postseason and missed the 2009 Japan Series.
Greisinger continued his next two seasons with the Yomiuri Giants with injury plague seasons. He finished the 2010 season with an 0–2 record and a 5.48 ERA in only six games. He pitched in nine games during the 2011 season and was 1–5 with a 4.15 ERA.
For the 2012 season, Greisinger pitched for the Chiba Lotte Marines and turned back the clock. He finished the season 12–8 with a 2.24 ERA in over 168 innings. During the 2013 campaign, he only pitched in 13 games and finished the season at 5–4 with a 4.54 ERA.
Through his seven seasons in Japan, Greisinger had a 64–42 record with a 3.16 ERA in 885 innings.
Greisinger was a member of the 1996 Summer Olympic baseball team, winning a bronze medal.
Greisinger married Joana Bennett in a ceremony in Florida. Joana is a Technology Consultant at Accenture and President of a Non-Profit Organization called One Vision One World.
