We love building great things at Cornerstone Defense, but we love showing up for our local communities even more! Recently, a handful of our awesome team members swapped their keyboards for backpacks 🎒 and stepped out in North Carolina to volunteer with Crossnore Communities for Children.|
The mission? Stuffing backpacks packed with essential gear for amazing youth entering the foster care system. 🧸💙 Crossnore does incredible work weaving a fabric of resilience in homes and schools, and since their impact relies heavily on volunteers, we were hyped to jump in and lend a hand last month! 🙌🎉
Who’s teaming up with us next? 🤝🚀
We are always on the lookout for new ways to get involved and give back. If your organization is hosting a volunteer event or wants to partner with us for a community initiative, let’s make it happen!

Level 99 in Tysons was the perfect playground for some serious team building! We put our minds and bodies to the test, tackling everything from intense physical and mental challenges to crawling through intricate mazes and even dodging axes! 🪓👀
Beyond the fun and games, we were blown away by the incredible, immersive artwork built into every single game room. Win or lose, the vibes were unmatched—especially complemented with some truly amazing food and drinks. 🍕🍹It’s safe to say we had an unforgettable experience pushing our limits and laughing the entire time!
