DENVER — President and CEO Joe Ellis joined 43 other CEOs on Thursday for the fourth annual CEO Build.

The Denver-based, C-level executives worked at Habitat for Humanity's Sheridan Square site to get their hands dirty and build provide affordable housing for more than 63 families.

The event, let by Habitat for Humanity of Metro Denver CEO Heather Lafferty, was the largest build since the CEO Build began in 2014.

"It's a wonderful cause and you're really doing something meaningful [by] building a home for somebody," Ellis said. "It's great work that Habitat for Humanity does, enabling people to own their own homes, providing this in a program that's sustainable and carries on and builds families and gives them a great foundation."

The Broncos' partnership with Habitat for Humanity began in 2012, and Ellis said Thursday the group gives families "a lifetime of dreams" when they're able to assume affordable ownership of their own homes.

"This is always a great day, where we have leaders who are passionate about giving back to our community," Lafferty said, "and we are so grateful for their support.

"CEOs have a way of just coming out and getting things done. It's amazing how everybody comes together. They may be competitors outside of the Habitat site, but when they come out here, we are all partners. We have one mission, one goal, and that's to ensure that some day, every human being has a good place to call home."

Added Ellis: "They've been a great partner. Heather Lafferty does a great job running the Denver-area Habitat for Humanity program. I think for everybody, we have four or five builds throughout the organization during the year. Everybody that participates really understands just how meaningful it is and how you're making a difference in a family's life."
