Kilpatrick Townsend & Stockton has chosen a new leader, three weeks after the firm’s chairman, Paul Aguggia, announced he will leave to become the head of Clifton Savings Bancorp., a New Jersey bank client.

The firm’s new chairman is J. Henry Walker IV, in Atlanta, who had been the firm’s managing partner. Susan Spaeth, in Kilpatrick’s Silicon Valley office, succeeds Walker as managing partner. Both are members of the firm’s executive committee.
