Jack Morton Worldwide has promoted two top execs and hired back a third.

President-U.S. Laura Shuler adds the title of chief strategy officer, to expand the shop's global strategy and planning work—which should, in turn, improve Jack Morton's audience research.

Chris Cavanaugh will be promoted to chief client officer, a new global post designed to bolster client services. He had been executive VP-managing director of Jack Morton's New York office. He takes his new post on Sept. 1.

Laurence Croneen returns to Jack Morton to replace Cavanaugh at the helm of the New York office. He had been managing director of the London office from 2000 to 2005. He rejoins Jack Morton on Sept. 1.

Jack Morton ranked No. 35 in the 2006 PROMO 100 with estimated 2005 net revenues of $116.3 million, up an estimated 5% from 2003.
