His joining adds important strength to our Antitrust and Competition practice and reflects Hausfeld’s continued investment in lawyers who are equipped to take on complex, high-impact competition matters.”

    The addition of Walker reflects Hausfeld’s continued focus on expanding its antitrust litigation capabilities. The firm maintains U.S. offices in Boston, New York, Philadelphia, San Francisco, and Washington, D.C., and also operates across the United Kingdom and continental Europe.
