Honoring Service, Changing Lives

At STO Building Group (STOBG), veterans and their families hold a special place in our hearts. Which is why Structure Tone’s partnership with Team Foster isn’t just important—it’s personal. It’s a way for us to honor that service and give back in a meaningful way. They sacrificed for us, and now Team Foster advocates for them.

Family Giving Tree

By partnering with Family Giving Tree, BCCI contributed to empowering over 30,000 Bay Area students from low-income families, equipping them with backpacks stocked with essential school supplies tailored to each grade level—from picking up a backpack tag at the Mountain View or San Francisco offices to donating pre-filled packs through the Virtual Giving Tree.

Bring Your Kids to Work Day

RC Andersen employees dedicated their time to building 70 bicycles for the entire second-grade class at Edreira Academy in Elizabeth, NJ, bringing joy and promoting healthy outdoor activity. In addition to donating the bikes and helmets, they also provided the children with their first riding lesson, making for an active and rewarding experience!
