Sean Buller joined the Warrior baseball program prior to the 2014 season as the Pitching Coach after an illustrious college and professional career. From 1995-1998, Buller was a standout pitcher at the University of San Francisco. During his senior campaign, he earned All-West Coast Conference Pitcher honors en route to signing with the Detroit Tigers in 1998 as a non-drafted free agent. After playing AAA ball with the Toledo Mud Hens in 2001, Buller signed with the Long Beach Armada independent baseball team in 2007 and served as both a player and coach until 2009.

Buller then began his coaching career in 2010 in Cerritos, CA, as he became the Head Baseball Coach at Valley Christian High School. For three years, he not only coached the baseball team, but he was also the school’s Athletic Trainer.

In 2014 under Buller’s guidance, the Warrior pitching staff finished 19th in the NAIA with an earned run average of 3.06. The Navy and Gold pitchers also ended the 2014 season second in the country in opponents’ batting average with a mark of .216. Buller also proved instrumental in the success of Warrior standout pitcher Jacob Kopra during the 2014 season, coaching him during his NAIA West Pitcher of the Year campaign. Following his All-American season, Kopra signed a professional contract with the Los Angeles Angels of Anaheim.

Buller serves as the Assistant Strength and Conditioning Coach for the Corban University Athletic Department, and he also teaches in the Human Performance Department (CorbanWarriors.com).
