Art and Michelle Gastelum are longtime City Hall insiders with deep ties to Los Angeles’ pay-to-play development culture. Art Gastelum, a former aide to Mayor Tom Bradley and head of the construction firm Gateway Science and Engineering, has been scrutinized in multiple public corruption probes involving developer influence at City Hall. His firm has faced allegations of improper billing, and his name surfaced in FBI subpoenas during the federal investigation into disgraced former Councilmember José Huizar’s real estate dealings. Gastelum helped host fundraisers for Huizar’s wife’s campaign and worked on major projects later linked to developer kickbacks, though he was never charged.
