E.J. Mills

Biography

A four-time NESCAC Coach of the Year, E.J. Mills has led Amherst to four undefeated seasons since 2009 and has solidified himself as one of the top coaches and defensive minds in the country. Having just finished his 32nd overall season on the Amherst sidelines, and his 28th as head coach, in 2025, Mills has been a part of 178 of the program's 671 total victories since 1877. Arriving in Western Massachusetts in the fall of 1993 and serving as a defensive coordinator through the 1996 season, Mills helped the team improve its record in each of his four years as an assistant alongside former head coach Jack Siedlecki. When Siedlecki made his move to take over as head coach at Yale University, Mills was named the interim head coach for the 1997 season and has been at the helm ever since. Amherst saw immediate success with Mills at the reins, posting 7-1 ledgers three times during his first 12 seasons before ultimately capturing the program's first perfect 8-0 record since 1984 in 2009. Since then, the Mammoths have notched three more undefeated seasons (2011, 2014 and 2015) and have captured four more NESCAC titles to increase the program total to six. Mills played baseball collegiately at the University of Dayton and graduated in 1988 with a bachelor's degree in history and secondary education.
