About AGīL

Nationally recognized for innovation and fiscal strength, Frank Martz has transformed Altamonte Springs. Under his leadership, the City maintains one of Florida’s lowest tax rates, minimal utility costs and more than 13 years of debt-free operations. Altamonte Springs has earned national recognition as a Money Magazine Top 50 U.S. city and a Top 10 city for small business by WalletHub.

Frank pioneered breakthrough mobility programs, including the nation’s first communitywide partnership with Uber, a state and federally funded demand-response transportation system and CraneRIDES, the first permanent autonomous vehicle service operated by a U.S. city. Working alongside City staff and community partners, he also supported the creation of the Altamonte Springs Science Incubator, which has provided STEM opportunities to more than 35,000 students and families.

His environmental initiatives were achieved through strong cross-department collaboration, resulting in the award-winning pureALTA water reuse system and one of the nation’s first floating solar installations. To expand innovation opportunities, Frank and his team established the Altamonte Global Innovation Lab, a platform that supports testing and development in mobility, environmental technology and smart governance.
