FTS members actively support the ALAF by serving on local boards and committees, raising funds and making financial contributions, providing patient education, developing position papers, reviewing documents for scientific merit, providing testimony before the Florida legislature, advocating for federal research funding, and serving on statewide coalitions.

Members of the Florida Thoracic Society serve on the Council of Chapter Representatives of the American Thoracic Society. The Florida Thoracic Society is an officially recognized specialty group of the Florida Medical Association (FMA) and is represented on the FMA Council of Specialty Medicine, FMA Council on Legislation and FMA Board of Governors and House of Delegates.
