SAN FRANCISCO — Wells Fargo announced this week that Dawn Martin Harp, the head of Wells Fargo Dealer Services, is set to retire this year, after more than 20 years of service.

She will remain with the company until April 1, and afterward the company will conduct an internal and external search for her replacement.

“Under Dawn’s leadership, Wells Fargo continued to build our market leadership position in the auto finance business,” said Franklin Codel, head of Wells Fargo Consumer Lending. “She moved our business forward to where we now work with more than 14,000 auto dealers, helping more than 3.7 million customers finance affordable vehicle transportation.”

Martin Harp was first appointed to lead the Dealer Services organization in 2001. During her tenure, she and Wells Fargo Dealer Services focused on building and strengthening relationships with dealer customers for both consumer and commercial finance needs, the company stated.

While she headed the company, Wells Fargo was the nation’s largest used-car finance source and one of the top two overall auto finance sources, with a portfolio that grew to more than $60 billion, the company added.

Before leading Dealer Services, Martin Harp served as the group’s COO. She also served as CIO and the director of network computing for WFS Financial before it was acquired by Wells Fargo.

She currently serves as a board member of the American Financial Services Association and is a member of the organization’s Auto Finance Committee and Women’s Leadership Council. Additionally, she is a member of the Wells Fargo Consumer Lending Group Diversity and Inclusion leadership committee.
