Twenty-five years later, we continue to remember the lives lost on September 11, 2001, and honor the courage shown in the days that followed.

In memory of those who died on 9/11, GHA had the opportunity to contribute to this year’s Oak Brook Healing Field, where 2,977 American flags have been placed at the Oak Brook Polo Grounds.

Our GIS and Land Surveying staff worked together to establish the field location and alignment, providing layout information to guide installation of the memorial.

We are grateful to contribute to a memorial that gives the community a place to remember and reflect.

Congratulations to Isabella Anfuso, winner of GHA’s 2026 Annual Intern Presentations!

Each summer, our interns put together presentations highlighting their work and experiences at GHA. Three are selected to present companywide, giving employees the opportunity to hear what they learned before voting for the presentation that best captured their internship experience.

Each finalist brings their own creative approach to the Intern Presentations, finding a different way to share their summer experience. Isabella shared a Water Resources Survival Guide, Kaydence Wesson told her story through Civil Design mood boards, and Ryan Lerman took a game-inspired look at his third summer with GHA.

Since 1985, GHA’s internship program has given students opportunities to learn through hands-on project experience. It’s Real Experience that creates Real Impact. Learn more about our internship program: https://ow.ly/gs2j50Zz2az
