MARIO DIAZ-BALART: DEDICATED TO SERVING SOUTH FLORIDA

Mario Diaz-Balart has a profound vocation for public service. He currently represents the residents of Florida’s 25th District in the U.S. House of Representatives. In Congress, Mario serves on the powerful and influential House Committee on Appropriations which sets the spending expenditures for the U.S. Government. On the Appropriations Committee he serves on three sub-committees: the Financial Services Subcommittee, of which he is the vice-chairman, the State and Foreign Operations Subcommittee, and Military Construction and Veterans Affairs Subcommittee.

Mario was first elected to the U.S. House of Representatives in 2002 to represent Florida’s 25th Congressional district. In 2010, Diaz-Balart ran unopposed for Florida’s 21st Congressional district. After the 2012 redistricting cycle, he was elected to the newly redrawn 25th Congressional district, which includes parts of Miami-Dade, Broward, Collier, and Hendry Counties.

Before he was elected to the U.S House of Representative, Congressman Diaz-Balart spent 14 years serving both in the Florida Senate and the Florida House of Representatives. At the time he was elected to the Florida Senate, Congressman Diaz-Balart was 31, making him the youngest person ever elected to the Florida Senate. Congressman Diaz-Balart distinguished himself during his tenure in the Florida Legislature as a trustworthy steward of Florida’s tax dollars, especially while he served as Chairman of the combined Appropriations / Ways and Means / Finance and Tax Committee.

In Washington, Diaz-Balart is still known as a fiscal hawk for his work first on the Budget Committee and now on the Appropriations Committee. It’s important for him that Congress judiciously use the tax-dollars of hard working Americans. He also feels it is an integral part of his job that he do all he can to keep America strong, both economically and militarily.

Throughout his tenure in Congress he has focused on improving our local infrastructure so that Florida’s 25th District can compete in both the national and international marketplace for good paying jobs. One prime example of his commitment to our local infrastructure is the millions of federal dollars he helped steer to widen I-75 in Collier County. This year he helped secure a provision in the Omnibus Appropriations bill that allowed for the Miami Harbor Deep Dredge project to move forward. Once the project is complete it is expected that it will lead to tens of thousands of new jobs and a significant economic impact to the area.

As a native South Floridian, Congressman Diaz-Balart understands the unique role the Everglades plays in our local ecology. So when he first arrived in Congress he founded the Everglades Caucus. As Co-Chairman of the Caucus he has helped bring together members on both sides of the aisle to help secure billions of dollars for the restoration of the Everglades.

Diaz-Balart was born on September 25, 1961 in Ft. Lauderdale, Florida to Rafael and Hilda Diaz-Balart, and is the youngest of four brothers (Rafael, Lincoln, and Jose). He studied Political Science at the University of South Florida in Tampa.

Diaz-Balart currently resides in Miami, FL with his wife, Tia, and their son, Cristian.
