Euro RSCG Life Chelsea has seen some churn in senior management since Ed Stapor ascended to a network role last year. Stapor's successor, Bernie Coccia, left the firm for Draftfcb after less than a year at the helm. In his place, Euro RSCG Life installed co-managing directors Steve Nothel and Michael Peto in April. Formed from a merger of the Becker and Ouestar units of Euro in 2004, Chelsea aims to trade on the chic, arty vibe of the downtown Manhattan nabe from which it takes its name. Chelsea handled the professional launch of Wyeth's Effexor follow-on Pristiq with its "Think Beyond Start" campaign, which broke last year, playing up the SNRI's simple dosing and tolerability.
