Our Mission

Sustainability That Works for Everyone

Our mission is to make sustainability simple and effective. We help teams integrate environmental responsibility, occupant well-being, and cost efficiency into every stage of a project—ensuring high-performing buildings from design to occupancy.

Experts in Sustainability. Partners in Progress.

We’re Argento/Graham, a sustainability consulting firm based in downtown Los Angeles. Our mission is to make sustainable buildings easier to create and maintain—from the earliest design conversations to post-occupancy performance. We integrate environmental responsibility, occupant well-being, and cost efficiency into every project we touch, helping clients meet ambitious sustainability goals without slowing down their process.

Since 2015, our team of LEED-accredited professionals, licensed engineers, and seasoned project managers has worked across sectors like retail, hospitality, healthcare, higher ed, and multifamily housing. We offer a full suite of services—including LEED and WELL certification, energy modeling, building commissioning, Title 24 and CALGreen compliance, and more.

We’re a certified California Small Business, led by principals Anne Argento and Duke Graham. And while we bring decades of experience to every project, we keep things nimble, approachable, and hands-on. We solve problems before they become problems—and when you call, you’ll always hear from someone who knows your project.
