After building up a reputation as an up-and-coming corporate and capital markets lawyer at Dechert, where he was a partner for 12 years, Washington, D.C.-based William Tuttle landed at Proskauer Rose this week.

Trading one out-of-town firm for another, Tuttle will be a partner in Proskauer’s D.C. office. The New York-based firm has more than a dozen partners and about 30 lawyers in Washington. Philadelphia-based Dechert has more than 100 lawyers in the capital, including more than 40 partners.
