Peter Pierce, former president/CEO of information management provider Iron Mountain Inc., this week became president and chairman of TeleSpectrum. Former president/CEO Vincent J. Ciavardini, who took the job in August, left the company while former chairman F.R. "Pete" Talbott will remain on the company's board of directors. TeleSpectrum also named Christopher J.
