Ally Financial’s president of dealer financial services will take on additional responsibilities at the beginning of February — at least for the interim.

Ally announced on Friday that Doug Timmerman will become the company’s interim CEO on Feb. 1, following the departure of current CEO Jeffrey Brown on Jan. 31.

Brown announced in October plans to step down as CEO of Ally Financial to become president of Hendrick Automotive Group.

During Timmerman’s more than 30 years at Ally, he has held a wide variety of leadership positions across the company’s auto finance and insurance business, most recently serving as president of dealer financial services where he is responsible for deepening relationships with 22,000 dealer customers.

Under his leadership, Ally said it has “cemented its position” as a leading prime auto finance company, optimizing the business significantly and increasing and diversifying the dealer customer base.

“Doug’s long tenure at Ally and expertise in auto finance is extraordinarily well respected both inside and outside of Ally. I know he will ensure a seamless transition as the board continues working with a leading search firm to identify the next permanent CEO,” Ally’s chairman of the board Franklin Hobbs said in a news release.
