Duke Graham

PRINCIPAL, CO-FOUNDER

P.E., CBCP

  • Duke leads Argento/Graham’s energy services with a focus on implementation, systems-thinking, and turning big ideas into real-world impact. He’s helped deliver landmark projects like the LAX Automated People Mover, the Grand Avenue development, and the Intuit Dome–all while ensuring sustainability goals translate from the design phase to the construction site.

    Duke is fascinated by how things work–especially this planet–and brings that curiosity into every facet of his leadership. Known for being thorough, adaptable, and grounded, he’s the kind of partner you want when tackling complex sustainability systems.

    When he's not leading big builds, he’s likely camping, making music, or tracking down tacos. He once lived out of a van on a surf trip through Mexico–with no GPS and no phone, just instinct and the tide!
