Dietrich, who has been the pitching coach at Cal State Fullerton for the past three seasons and the recruiting coordinator the past two seasons, is considered one of the elite pitching coaches in the nation. Not only has he helped the Cal State Fullerton pitching staff set single-season records in earned run average, fewest walks, walks per nine innings pitched, hits per nine innings pitched and shutouts during his three seasons but his pitching staffs have led the nation in strikeout-to-walk ratio all three years.
Under Dietrich's guidance, junior pitcher Thomas Eshelman has earned All-American honors all three seasons. Eshelman joined his teammate, pitcher Justin Garza, on the USA Baseball Collegiate National Team during the summer of 2014.
Six of Dietrich's Fullerton pitchers have been selected in the Major League Baseball Draft, including 1-2 round sandwich pick Michael Lorenzen in the 2013 draft and Thomas Eshelman in the 2nd round of the 2015 draft.
Prior to coaching at Fullerton, Dietrich coached at UC Irvine, the last two as the pitching coach. During those two seasons, his pitching staff had a combined ERA of 3.10 and a WHIP (walks and hits per innings pitched) of 1.18.
In 2012, his UC Irvine staff set a Big West Conference record for fewest hits allowed (422) in a season. The staff was led by first-team all-conference sophomore Andrew Thurman, who was a 2nd round selection in the 2013 MLB Draft.
In 2011, the Anteaters posted their lowest ERA (2.95) in nearly 40 years. He helped junior Matt Summers become the Big West Conference Pitcher of the Year as well as making several All-American teams. Summers was drafted in the 4th round of the 2011 draft by the Minnesota Twins.
He has also served as the pitching coach at Irvine Valley Community College, Los Angeles City College and Cal State Los Angeles.
