Mike Mongelli

With a construction career that began in high school, Mike exemplifies that experience is knowledge. As a teen growing up in Nevada, Mike performed underground pipe installation and cabinetry work before moving to Arizona in 1978. Mike earned a BS from ASU’s College of Construction in 1983.

After working for various development and construction companies, Mike became Willmeng’s COO in 2011, and in 2020, he was named President. His leadership provides a dynamic dimension to Willmeng, and his diverse knowledge has positioned Willmeng as a leading general contractor in Arizona. Mike’s experience guides roughly 190 employees in critical projects and daily business operations, from preconstruction to project completion. As a Leed Accredited Professional, sustainability drives Mike’s approach to projects.

When not in the office, Mike focuses on spending quality time with his family. He also enjoys boating, traveling, and volunteering. As part of the company culture, Willmeng supports 85 non-profit organizations, and Mike frequently dedicates time and resources to The Andre House and NAIOP Arizona’s Feeding the Homeless.

“My greatest satisfaction at work is the clients and our great company culture where we believe and act on the notion that there are no substitutes for honesty and integrity.”
