Every expedition includes a few memorable stops along the way. 🌎

We recently welcomed participants from the Zachry Women Breaking Ground leadership conference to our cement plant, where they got a closer look at our operations and met the talented team behind them.

As part of this year's Around the World: The Leadership Expedition, several of our team members also joined the journey, exchanging ideas, sharing experiences and gaining fresh perspectives.

Like any great expedition, the journey doesn't end at the final stop. It's what we learn along the way and bring back to our teams that makes the journey even more meaningful.

Grateful to have been part of the experience and proud of everyone who helped make it happen!

It's always nice to step away from the day-to-day and spend time with our neighbors. 💚

Our Rio Medina Quarry team participated in Hondo’s National Night Out, an annual event that brings residents, first responders and local organizations together to build relationships and strengthen the community.

We're grateful to have been part of the evening and appreciate everyone who stopped by to say hello. A special thank you to our team members who helped make it possible!
