Throughout his career, he has also represented some of the largest asset management and private equity firms in the United States on domestic and international transactions spanning emerging markets, Latin America and Asia.

Carrigan has served in significant in-house leadership roles, including chief legal officer and chief compliance officer at Little Harbor Advisors, LLC and principal and senior counsel at State Street Corporation. He regularly advises investment advisers, private funds, fund boards, executive teams and founders navigating growth, capital raising, compliance and strategic transactions.
