ANN ARBOR, Mich. -- Warde Manuel, the University of Michigan's Donald R. Shepherd Director of Athletics, announced Wednesday (May 24) that men's and women's swimming and diving head coach Mike Bottom will retire from the university, effective Aug. 4.

Bottom will continue to lead both U-M programs while a national search for his replacement progresses.

"Today, Mike Bottom informed us that he plans to retire from full-time coaching," said Manuel. "An Olympic caliber coach, Mike sustained Michigan's legacy of success in the pool for many years and will always be remembered for stewarding great success in men's and women's swimming and capturing the 2013 men's national championship. I deeply appreciate his passion for the sport, his love of U-M, and his willingness to continue leading the program while we search for his replacement."

"Following my 15th year leading Michigan teams and over 30 years of collegiate coaching, my excitement moves to cheering on future success. In the coming weeks, I will enjoy being part of our summer national and international pursuits. I am excited to pass the helm to a fresh new leader who will win championships and mentor champions. I am so grateful for the leadership of Warde Manuel and Rob Rademacher over these past years and the growth partnerships that I've enjoyed with so many coaches and staff members. Go Blue!"

Bottom recently completed his 11th season leading the combined programs and his 15th year leading the men's program while coaching in six consecutive Olympic Games. The nine-time Big Ten Coach of the Year compiled a 111-13-1 (67-9 Big Ten) duals record with the men's program and a 74-19 (49-9 Big Ten) duals record with the women.

Bottom will finish his U-M tenure having coached nine national champions, 140 Big Ten individual and relay champions, and more than 50 CSCAA All-Ameicans.

Overall, Bottom led the Michigan men to one national championship (2013) and nine Big Ten championships while leading the women to three titles. In addition, Bottom coached nine individual national champions in his tenure.
