Simpson Thacher & Bartlett announced Monday its addition of former U.S. Securities and Exchange Commission associate general counsel David Blass as a partner for its investment funds practice in Washington D.C.

Blass joins the Wall Street firm after nearly three years as general counsel for the Investment Company Institute (ICI), a trade association for the investment funds industry based in the nation's capital.

“The opportunity at Simpson Thacher [with] the combination of work they do [and] my background syncs up so well,” Blass said of his move. “It's just too good of an opportunity to pass up.”
