Management team changes under new Dex One Chief Executive Officer Alfred Mockett continue.

The yellow pages and Internet advertising firm said Thursday that Chief Financial officer Steven Blondy will leave the company “on or before” July 31.

Dex One (NYSE: DEXO) described the “separation was mutually agrred upon by the company and Blondy.”

“We thank Steve for his valuable service to Dex One and its predecessor company R.H. Donnelley,” Mockett said in a statement. “Since joining the company in 2002, Steve has played an important role in expanding operations and improving the company’s cost structure.”

Dex One said it had retained a search firm to find a replacement.
Mockett took over as CEO last September. Since January, he has made four changes in his management team.
