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.”

🌟 Employee Spotlight: Nikki Hutchens 🌟
 
Meet Nikki Hutchens, one of our talented Systems Administrators! Nikki discovered us through ClearanceJobs and has had a unique journey into the IT world. With a degree in biochemistry, she started her career in the dairy and nonprofit industries before making a bold pivot into IT. After earning certifications in help desk work, Nikki landed her first Systems Administrator role — and quickly realized not only was she good at it, but she loved it. She’s embraced the fast-paced nature of tech, always pushing herself to learn, grow and continue adding certifications and more experience to her resume.
 
Nikki’s career advice? “Keep an open mind and be open to new and different opportunities. Don’t be discouraged by an end — it can be a new beginning!” Outside of work, Nikki enjoys knitting and diving into sci-fi and fantasy books. Regarding Cornerstone Defense, she especially appreciates that our company invests in its people, noting this is the first place she’s worked with a dedicated training budget to help employees grow. Nikki’s go-to motto is something they’ve always said in her family: “It’s always better to know” — because knowing the truth, even when it’s tough, allows you to take action and make positive change. We agree, and we’re so lucky to have Nikki and her positive outlook on our team!
