Scottsdale's organization: experienced leaders focused on service and efficiency
Scottsdale City Manager Greg Caton has implemented a series of organizational changes designed to streamline operations, improve internal coordination, and keep senior leadership more connected to day-to-day service delivery and top city priorities.
The city's organizational structure builds on the depth of experience within the city's leadership team, who are seasoned professionals with decades of public service and a broad range of expertise across municipal functions. The team also includes a bevy of "home grown" talent, people who began their careers with Scottsdale and have advanced through the ranks while building an incredible foundation of knowledge and experience in Scottsdale.
“This leadership team brings a strong track record of public service and commitment to our community,” said Caton. “Our new structure increases responsiveness by reducing layers of bureaucracy, which helps senior staff stay directly engaged with the work that matters most to our residents. It also helps our 2,700 employees — who bring valuable skills and experience to their roles every day — do their best work and deliver the highest level of service."
