Employee Voices

We are happy to share about the meaning of our Culture at Cornerstone Defense, but we are thrilled when an employee can share the same sentiment. Here’s a recent review from our Cornerstone Defense Glassdoor page that we hope gives insight into working at Cornerstone:

“Working at Cornerstone Defense has been an incredibly rewarding experience, and I couldn’t be more satisfied with the way this company treats its employees. From the moment I joined, it was evident that employee well-being is a top priority here. One of the standout features of working at Cornerstone is the emphasis on creating a positive work environment through various employee events and initiatives. Whether it’s team-building activities, wellness programs, or celebratory events, there’s always something happening to foster camaraderie and boost morale among the staff. These events not only create a sense of belonging but also contribute to a happier and more cohesive workplace. Moreover, I am truly impressed by Cornerstone’s commitment to giving back to the community through its charitable contributions. It’s heartwarming to see the company actively involved in supporting meaningful causes, and it instills a sense of pride in being part of an organization that values social responsibility. What sets Cornerstone apart is the accessibility and approachability of top management. Unlike some companies where senior leadership feels distant or unapproachable, here, the top managers are not only accessible but also genuinely interested in hearing from employees at all levels. They actively solicit feedback, listen to our ideas, and take proactive steps to implement positive changes based on employee input. Furthermore, Cornerstone is committed to fostering a culture of fairness and transparency. I appreciate how decisions are made with fairness and equity in mind, and everyone’s contributions are recognized and valued. This creates a sense of trust and mutual respect among colleagues, which ultimately leads to a more harmonious and productive work environment. In summary, working at Cornerstone has been an enriching journey characterized by a supportive work culture, meaningful employee engagement initiatives, and a genuine commitment to making a positive impact both within the organization and in the broader community. I feel fortunate to be part of such a forward-thinking and employee-centric company.”

🎨✨ 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! 💫
