Happy almost International Women’s Day! (Coming up this Saturday, March 8th!) To celebrate in advance, some of the incredible women on our team took a well-earned break for manicures, pedicures, and great conversations. Because strong teams are built by and with strong women — and a little self-care goes a long way. ✨

Employee Spotlight alert! Our Q4 Company Newsletter was about reflecting on the past year, and our Office Admin and Marketing Assistant, Terry Kim, provided a heartfelt blurb on her first six months at Cornerstone Defense. We loved to hear her sentiment, since creating a positive working environment and supporting our employees work-life balance are two things we certainly strive for. Let us know what you think of Terry’s spotlight, and if so, drop us a comment and start a conversation! ⭐⭐
 
“As a somewhat recent grad, I wasn’t sure what to expect when transitioning into this new chapter of my life. Throughout high school and college career, I had several part-time jobs, but I don’t recall having any truly memorable or enjoyable experiences at them. I didn’t realize how crucial a positive work environment was until I started here at Cornerstone. On my first day, I was very nervous and unsure, but by the end of it, those nerves faded. The level of positivity in the office made me reflect on how unfair I had felt at my previous jobs, where the negative atmosphere affected my mood, and in turn, my drive and motivation suffered. Having supportive colleagues and managers makes an incredible difference, and the interpersonal relationships that I’ve built here at Cornerstone have made me more eager to come into work every day and give my best. Cornerstone Defense is my first “big girl job,” and so far, it’s been filled with nothing but positive, uplifting experiences. I’m looking forward to continuing with such a warm and welcoming company as we transition into 2025!”
