John Beilein’s coaching staff at Michigan will have a different look next season.

Associate head coach Jerry Dunn and assistant coach John Mahoney, both of whom came with Beilein to Ann Arbor from West Virginia three years ago, will both be leaving the Wolverines program to pursue other opportunities.

Beilein promoted administrative specialist Jeff Meyer to an assistant coach. He had been in that role since Dunn took a leave of absence in December.

The departures leave one opening on Beilein’s staff after a 15-17 year, the second losing season in Beilein’s three years in Michigan.

“I have a clear vision of where I want this program to go and how I would like to complete my coaching staff,” Beilein said in a statement. “I see this change as a unique opportunity to add another highly qualified individual to our Michigan basketball program.”

Beilein will have to replace two men with prior head coaching experience. Dunn was previously a head coach at Penn State from 1995-2003. Mahoney was a head coach at Mount Aloysius College - a junior college-turned-NAIA school - from 1994-98.

When Dunn returned from his leave of absence, he slid into Meyer’s administrative role and Meyer, a former head coach at Liberty, stayed in the assistant’s position.

“I want to be a head coach again and the only way to be fair to the program is to pursue these opportunities with my entire focus,” Dunn said in a statement. “I have enjoyed spending the past seven years with John. We have had a lot of success together and I have learned a great deal during that time.”

A text message sent to Dunn on Friday evening was not immediately returned.

Mahoney, 49, was the director of basketball operations under Beilein at West Virginia before being promoted to assistant coach when he arrived at Michigan.

“It’s never easy to leave a program that you have worked so hard to build,” Mahoney said. “But I am looking forward to this next progression of my career and my pursuit of becoming a collegiate head coach.”

Mike Jackson is the only assistant coach remaining from Beilein’s initial staff when he was hired in 2007.
