"It is with great sadness that I step away from Husson, but due to personal matters this is what is best for me and my family at this time. I want to thank the University, Athletics Staff, Coaches, current and former players for all they did for me during my time at Husson," Harvey said.
In his 12 years as head coach the Bucksport native won 284 games, the most in program history, and led the Eagles to the NCAA Tournament twice.
"We are very sad that Jason will be leaving us," Husson Director of Athletics Frank Pergolizzi said. "He has made a significant contribution to both the baseball program and the athletic department during his time at Husson. The young men who have had the opportunity to play for him are very fortunate. We wish him and his family the very best."
A three-sport athlete at Husson, Harvey scored over 1,000 points as a basketball player and was inducted into the school's hall of fame in 2012.
Harvey did not respond to a request for comment and Husson will open up a search for its next head coach.
Bench coach, Jason Folsom, has been the bench coach for the last 13 years and assistant coach Brandon Portwine just concluded his seventh season with the team.
