Mary Moore Hamrick is making the switch back to the for-profit sector, signing on as head of government affairs for accounting giant Grant Thornton. Hamrick, who will be national managing principal of public policy, will represent the firm before Congress and with regulators--including the Public Company Accounting Oversight Board, where she spent nearly six years, before leaving in early 2009.

Hamrick, whose Washington career includes a stint as Republican counsel to the House Energy and Commerce Committee and nine years as top lobbyist for the New York Life Insurance Co., spent the last year at the non-profit Center for Audit Quality.
