"While I likely will always identify as a coach, after nearly four decades on the bench, it's time for a new challenge," Joseph said in a press release. "I've had the honor to be the head coach for more than 1800 games, and I cannot overstate my gratitude to my players, coaches, administrators and staff for allowing me to live out my professional dream. I'm extremely proud of what my players have accomplished on and off the field. They've provided me with a lifetime of memories. I appreciate the confidence that Athletic Director Alan Haller and Deputy AD Jennifer Smith have shown in asking that I contribute to the department in a new manner. I look forward to working toward enhancing the experiences of our student-athletes and coaches from a different perspective."

Joseph will remain with the Michigan State Athletic Department in a sports administration role.

"Jacquie Joseph has made a career of positively impacting the lives of her student-athletes both on and off the softball field," Haller said. "She has long been a valued voice in the athletic department and I look forward to her contributions in her new role. She truly cares for everyone in Spartan Athletics and is always willing to offer her perspective if it benefits the department. Both of these attributes will serve her well in her new role."

Taking over the program ahead of the 1994 season, Joseph is the winningest coach in program history, eclipsing 750 wins this past spring. Under her watch, the Spartans made four NCAA Regional appearances, including a Big Ten Tournament title in 2004.

Joseph's retirement adds another to the list of Michigan State Athletics' head coaching search. Since Haller took office in September, MSU has hired Leah Johnson as the new head volleyball coach and Adam Nightingale as the new head hockey coach. Michigan State is also looking for a new head coach for the men's tennis team following Gene Orlando's retirement last month.
