Community Champion Spotlight ⭐️

Recognizing our own Sierra White and the work she’s leading through Go Lead Idaho.

Go Lead Idaho brings women across Idaho together to connect, learn, and grow as leaders. As president, Sierra puts her time and energy into building that community and opening doors for the women in it.

As our Community & Marketing Development Manager, she brings that same heart to McAlvain every day.

Building up the people around you is the best kind of leadership 💪

Hispanic Heritage Month, McAlvain style. 🎉

So much of what we build comes from the skill, work ethic, and families of our Hispanic team members and trade partners.

Swapped the classroom for the jobsite. 👷‍♂️

COSSA high school students from Wilder, ID spent the day with our site teams, getting a firsthand look at our ACHD, YMCA, and Farm Bureau projects. Workforce development starts with showing students what’s possible.

Thanks to the COSSA teachers and students for making the trip, asking questions, and showing up ready to learn.
