🎧 Cornerstone Defense: 2025 Wrapped
We had over 13,000 applicants this year (even we’re surprised by that number! 😲). Of those, more than 7,000 were eligible—cleared and ready to support the mission. 🌎 Applicants came from over 3,000 cities across the country, bringing with them a rich tapestry of backgrounds, experiences, and perspectives—including a strong representation of veterans and diverse communities. 🇺🇸🌍 And here’s the kicker: 80% of those who interviewed were hired—because when we meet the right people, we know it. 💼✨

We’re proud of the talent we’ve connected with this year, and we’re even more excited to meet new faces, grow our team, and expand our network in 2026. 🚀 Whether you’re looking to join us or collaborate, we’re ready. We can’t wait for what’s to come in 2026! 🎉 #CornerstoneWrapped #DefenseCareers #HiringStats #2025Recap #2026Goals #VeteransWelcome #DiversityInDefense

🎨✨ At the 20th Annual National Business Leadership Conference last month, a few of our Cornerstone ladies got creative in a breakout workshop that connected art to leadership!
 
From painting at the tables to exploring how leadership styles — democratic, visionary, transformational — can be seen like different art styles 🖌️👩‍🎨, the energy was inspiring and full of color. Our attendees were truly motivated and had SO much fun 💡💃. Leadership never looked this vibrant! 🌈🙌
 
What other metaphors can you think of that relate art and leadership to each other? Drop us a comment — we’d love to hear your creative ideas!

We’re back with a Image attachment

🎶 “Glimmers of Resilience” In our latest newsletter, we explored resilience from the lens of Virginia Blair, our Director of Marketing and Operations. And not just resilience, as a buzzword, but as a lived experience. One story stood out: a memory sparked by a Beatles song, a childhood car ride, and the lyric that became a lifelong mantra—“Nothing’s gonna change my world.” 

Resilience doesn’t always look like powering through. Sometimes, it’s found in the quiet moments: a favorite song, a shared laugh, a memory that reminds us who we are. It’s in the “glimmers”—those small, joyful sparks that help us stay grounded, even when life feels uncertain.

As we close out Q3, we’re reflecting on the power of those glimmers—and how they help us show up stronger, together.

Want to know what it’s like to work on a team that values joy, connection, and the human spirit? Reach out today. We’d love to share more! 💫
