In the fall of 1972, he was hired as an associate at
First Boston, where he worked in the
mergers and acquisitions department. He remained with First Boston until 1988 when he teamed up with associate
Bruce Wasserstein to create their own mergers and acquisitions advisory business as
Wasserstein Perella & Co. Their company was at the forefront of the 1980s/90s boom in corporate takeovers, and Perella was described by the
Financial Times as "famed on Wall Street for transforming mergers and acquisition into a glamorous, moneymaking business in the 1980s". Perella left Wasserstein Perella in 1992/1993 to join
Morgan Stanley, where he was first head of mergers and acquisitions, and then the chairman of the Institutional Securities and Investment Banking Group. In 2005, Perella and other top executives resigned from Morgan Stanley in the wake of policy disagreements with Chairman
Philip J. Purcell. Purcell soon resigned following more high level departures from Morgan Stanley. One of the deals Perella advised on following his departure from Morgan Stanley was the Bank of America takeover of credit card company
MBNA. In November 2005, Perella and former Morgan Stanley banker Terry Meguid announced that they were opening an investment banking boutique. In June 2006, Perella announced the formation of a new financial services firm,
Perella Weinberg Partners, based in New York and London. ==References==
