Green Dot Corp. on Tuesday said it has appointed Grace Wang as chief financial officer, effective Nov. 18. She succeeds John Keatley, who left last month.

Wang joins the Monrovia prepaid debit card company from JPMorgan Chase & Co., where she has worked since 2004. A Pasadena native and graduate of Harvard University, she most recently was based in London as managing director and chief financial officer of investor services sales for Europe, Middle East and Africa.

Keatley notified Green Dot in April that he would be leaving the company as of Sept. 1 to take a position in Sweden.

Green Dot shares closed down 84 cents, or 3 percent, to $24.37 on the New York Stock Exchange.
