Corcoran founded Corcoran & Associates with his wife Jessica Ray Corcoran (b. 1972) in 2001. His early business was buoyed by easy access to his ally Byrd, who became House Speaker in 2002. This influence was criticized, as was Byrd's hiring of Corcoran's sister Jacqueline ("Jackie"). With the addition of Jeff Johnson, the firm became Corcoran & Johnson. In 2019, the firm was rebranded Corcoran Partners. In 2021, Corcoran Partners took in $5.9 million in lobbying fees. Corcoran & Johnson's revenue expanded considerably in 2018. In 2012, the firm generated $2.4 million in legislative fees. Corcoran is the capital lobbyist for a nonprofit owned by the husband of Sarasota County Commissioner Teresa Mast and in August 2025, he was one of only two applicants entering the bidding for the capital lobbyist for
Sarasota County due to issuance of the county invitation as a private bid sent only to six firms. After public disclosure, the bidding process is now rescheduled. == Political committees ==
