Manheim has named six new general managers of its auto auctions, including a new leader for its Southern California Market Center.

Promoted to that role is Tom Wemhoff, who is now head of the Southern California Market Center and GM of Manheim Riverside. That Market Center includes Riverside along with Manheim California, Manheim Oceanside, Manheim Southern California and Manheim Hawaii.

Wemhoff replaces Chris Brown, who was recently promoted to the role of vice president of Mobile Inspections following the acquisition of Alliance Inspection Management. Wemhoff was previously GM of both Manheim California and Manheim Southern California.

Succeeding Wemhoff is Jessica Albright, who is now GM of Manheim Southern California after her most recent post as assistant GM of Manheim Riverside.

Meanwhile, with Mike Browning moving up to the role of associate vice president of industry operations, Manheim San Antonio has a new GM: Sandra Santas, who was most recently the auction’s AGM.

Next, Shawn Springer has been named GM of Manheim Central Florida after previously leading Manheim St. Pete.

Christina Flatt succeeds Springer as GM of Manheim St. Pete after her time as AGM for the company’s Tampa Market Center.

Manheim Utah has a new GM in Matt Kirkwood, who was mostly recently AGM in Dallas.

“These appointments showcase the caliber of leadership within Manheim and our focus on aligning talent with strategic growth,” said Alan Lang, senior vice president of physical services and auctions at Cox Automotive. “Each leader brings unique experience and perspective to their new role, and we’re excited to see the impact they’ll make.”
