I am proud to lead Pinnacle West Capital Corporation and Arizona Public Service, the state’s largest electric company that provides power to 1.4 million customers. APS is committed to providing reliable and affordable service to the people of Arizona. As our state grows, we’re expanding and modernizing the grid to meet the changing energy landscape and build resilience for the future. Since joining APS nearly 25 years ago, I’ve worked across the company in various areas of the business, including as President, Chief Financial Officer, Chief Information Officer, and General Manager of Transmission and Distribution Operations. As a third-generation Arizonan, I am passionate about serving our communities. I serve on the boards of the Nuclear Energy Institute, Arizona Chamber of Commerce and Greater Phoenix Economic Council and am an Honorary Commander of the Luke Air Force Base. My leadership promise is to foster a culture of collaboration, accountability and excellence, where team members can learn and grow.
