Protecting our communities goes beyond the job site. Our Salt Lake City and Ogden, Utah, teams recently rolled up their sleeves for a blood drive with the American Red Cross, helping save lives through blood donation.

Their efforts are part of our 2026 community service challenge in honor of our 80th anniversary. Thank you to everyone who gave their time and donated!
