Dex One, the Cary yellow pages publisher that continues to shake up its operations to offset slower sales, today named a new chief financial officer.

Gregory Freiberg, 44, joins the company on Sept. 12. He replaces Steven Blondy, who stepped down as CFO in July. Blondy had been CFO of the company previously known as R.H. Donnelley since March 2002.

Freiberg will report to Alfred Mockett, who took over as CEO nearly a year ago. Since then, Dex One has been remaking itself into a digital business, as customers shift away from traditional print yellow pages. The economic slowdown has also hurt advertising sales, and Dex One is still losing money.
