Weil Gotshal & Manges boasts one of the largest US antitrust practices in the GCR 100, with a headcount of 98 – including 33 partners – in New York, Washington, DC, London and Paris. That figure includes five Who's Who nominees. Practice heads Steven Newborn and Helene Jaffe are both highly recommended by peers, while New York partner Debra Pearlstein is described as "very bright and very thorough". Weil Gotshal also received a number of votes from rival firms. Little wonder, then, that it ranks 17th in the inaugural GCR 20.
