Current office and Treasure Coast connection
Brian Mast represents Florida’s 21st Congressional District in the U.S. House of Representatives. A Republican, he began congressional service on January 3, 2017. In the 119th Congress he chairs the House Foreign Affairs Committee and also serves on Transportation and Infrastructure. His earlier career includes Army explosive-ordnance disposal work and civilian federal security assignments. His official biography identifies Fort Pierce as his home, and his office maintains several Treasure Coast-area contact locations. S1S2S3
Mast was born in Grand Rapids, Michigan, on July 10, 1980, and graduated from South Christian High School in 1999. His educational record subsequently connects him with Florida through attendance at Palm Beach Atlantic University. The historical record distinguishes these early years from the later Florida constituency he represents. S1
Education and Army service
The House historian records attendance at Palm Beach Atlantic University during 2000–2002 and American Military University during 2008–2010. Mast earned an A.L.B. from Harvard University Extension School in 2016. Naming the Extension School and the actual credential is more precise than implying a different Harvard program or adding degrees from institutions where the record establishes attendance only. S1
His Army service ran from 2000 through 2012. The official biography describes explosive-ordnance disposal work, including deployment in Afghanistan, and identifies military decorations including the Bronze Star and Purple Heart. It also describes the combat injuries in which he lost both legs. These are publicly documented features of his service; this profile does not add graphic medical details or speculate about private treatment. S1S3
Recovery and civilian federal work
Mast’s official biography explains that he remained on active duty during recovery and provided expertise to federal agencies. The congressional historical record identifies work as an instructor for the Bureau of Alcohol, Tobacco, Firearms and Explosives, an analyst for the National Nuclear Security Administration in 2011–2012 and an explosives specialist for the Department of Homeland Security in 2012–2015. S1S3
Those entries show a transition from military service into civilian security work before Congress. They should not be interpreted as present operational positions. A member of Congress who previously worked with an agency does not continue to act as that agency’s employee through the congressional office.
The official account also describes later volunteer activity in Israel. That is distinct from his U.S. Army service and should not be combined with it as though it were another period of U.S. active duty. The biography’s focus remains the documented professional sequence rather than promotional descriptions of the experience. S3
Election and congressional responsibilities
Mast entered the House in the 115th Congress and continued into the 119th. His current seat is District 21. Earlier district numbers can differ following redistricting, so this profile separates the person’s continuous congressional service from the current seat label. S1S2
The Foreign Affairs chairmanship is confirmed in both the House historical record and his official committee page. It concerns the House’s work on foreign policy, oversight and legislation. The chair is not the secretary of state and does not independently conduct all U.S. diplomacy or command the armed forces. S1S4
His Transportation and Infrastructure role includes service on the Water Resources and Environment Subcommittee. The official committee page explains that the broader committee’s jurisdiction includes water infrastructure, flood-damage reduction and agencies such as the Army Corps of Engineers. These responsibilities connect with issues affecting waterways in Florida. S4
Water policy and the Everglades
Mast’s official materials identify Lake Okeechobee water-quality issues as a legislative priority. An October 2026 article on his site discusses the eighth anniversary of the authorization for the Everglades Agricultural Area reservoir and describes his role in the authorizing language. This is a dated account of legislative participation, not proof that every project component is complete or that a particular water discharge decision is under his personal control. S3S5
Water-resource projects can involve federal authorization, appropriations, agency implementation and state partners. A biography should distinguish those stages rather than credit or blame one legislator for every operational outcome. The project record and current agency notices are the appropriate sources for construction and environmental conditions. S4S5
Congressional forums and constituent work
Mast’s official committee page lists co-chair roles in caucuses including estuaries, conservation, explosive-ordnance disposal and the Coast Guard. Caucuses are member forums; they are not the same as standing committees with formally assigned legislative jurisdiction. Their subjects nonetheless show connections between his military background, coastal constituency and current policy interests. S4
His website also provides routes for veterans’ assistance, passport problems, academy nominations and federal-agency casework. A nomination or congressional inquiry is not a guarantee of appointment, a passport deadline or a benefits award. Readers should follow the relevant agency’s instructions as well as the office’s published process. S6
Public contact
The Washington office is at 2182 Rayburn House Office Building, Washington, DC 20515, with telephone 202-225-3026. The official website lists district locations in Port St. Lucie, Stuart, Jupiter and Fort Pierce, using the district telephone 772-403-0900. Hours and appointment arrangements should be confirmed before a visit. S2S3
This profile records Mast as the current holder checked on October 28, 2026. It is a neutral biography, not an endorsement or a prediction about the next election. Later transitions should update the seat’s current-holder link while preserving this person’s service history and the dates of the roles described here.
