In 1989, Mateo founded the Mateo Institute of Training, which worked to train non-violent, first-time offenders at
Rikers Island in vocational trades such as
plumbing and
carpetlaying. In 1993, amid a wave of
gun violence sweeping New York City, Mateo started Toys for Guns, a program by which residents could voluntarily turn in guns to the
NYPD in return for gift certificates to local
toy stores.
Civic advocacy In September 1998, after a spate of murders perpetrated against
taxicab drivers in
Brooklyn and
The Bronx, Mateo was appointed president of the New York State Federation of Taxi Drivers. As president, he successfully lobbied the
New York City Council to install
bulletproof partitions in the city's cabs. Mateo is a spokesman for United Bodegas of America, an organization which advocates for the owners of
bodegas (small, owner-operated convenience stores which are especially common in New York). In 2010, Mateo helped run a campaign to encourage New York's bodega owners to buy handguns as a deterrent to robbery.
Political activities In the mid-2000s, Mateo emerged as a leading
Republican activist and fundraiser. In 2002, he raised $400,000 for
New York Governor George Pataki's re-election campaign. In 2003, he was a major fundraiser for President
George W. Bush, who named him to the
White House Commission on Presidential Scholars. In 2004, he spoke at the
Republican National Convention. In 2005, Mateo served as Hispanic Director for the re-election campaign of then-New York City Mayor
Michael Bloomberg. In 2012, Mateo supported
Texas Governor Rick Perry's
presidential campaign, organizing a fundraiser for Perry in Manhattan's
Inwood neighborhood. In June 2025, Mateo supported
President Donald Trump's
Immigration and Customs Enforcement raids and deportations, saying "He's going after the right people" and "President Trump came in, and all the criminals are out. I applaud that." He said that United Bodegas of America gives bodega workers "the comfort of knowing that the president isn't going after them." ==Controversies==
