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.”

Keeping up with our New Year's Resolutions over here!🥳🙌🏻🎇 We're lucky to have a gym at our Herndon office, great for a quick workout before or after work, or for grabbing a buddy and walking on the treadmill during your lunch break, as a couple of our awesome team members did today. What New Year's Resolutions did you set this year? Somehow we are halfway through January already -- hope you're keeping up with your resolutions, and if not, don't despair there's still half the month left to get back on track! It's never too late to start again. 😉 ... See MoreSee Less

Need to thaw out after all the snow this week!? @Ned Devine's Irish Gastro Pub and Restaurant in Herndon is one of our favorite hangout spots year round, but it’s especially cozy in the winter to get out of the cold and warm up by the fire with some Bangers and Mash or Shepherd’s Pie. 🔥And if you also grab a drink 🍺, you might see one of our Cornerstone Defense pint glasses which Ned’s is currently featuring for us! If you swing by and see one of our pint glasses, snap a photo and send it our way! Thanks to the team and staff at Ned’s for the support and promotion — we couldn’t more highly recommend a fun place for a quick lunch meeting, a company happy hour, a delicious bite to eat or a place to go enjoy some great music, Trivia, and even line-dancing on Thursdays! 🎵💃🏻🎉 If you’re a fan of Ned’s too, drop us a comment and let us know why! ...

We are in full holiday mode at Cornerstone over the last couple weeks! Last week, we attended the annual Christmas Tea fundraiser hosted by the Loudoun County Social Collective, each year benefiting a different cause. This year’s proceeds went to SPARC Solutions (Special Adapted Resources Centers), and incredible organization that  provides essential day programs for adults with disabilities at six locations in Northern Virginia. The Social Collective was able to raise upwards of $50,000 for this fantastic cause, and we are so grateful we could be a part of  something that is so emblematic of what the holidays are really about! ❄️🎄💖 If you feel called to donate or learn more about SPARC, visit their website here: sparcsolutions.org/. ...
