We’re kicking off a new series: “Name the Local Spot!” 🎉 We’ve been proud to call Herndon home for over 10 years, and we truly consider ourselves part of this community. 💙 So, we certainly love when someone tells us they spotted a Cornerstone Defense glass out in the wild at one of our favorite local hangouts. So let’s play a game—can you figure out where this is? 👀
Here’s your hint (in rhyme, of course):
A place where stories, music, and cheer,
Fill up the night with friends far and near.
The name may recall a legend’s fame,
But can you guess this spot by name?
Drop your best guesses below ⬇️ and tell us… what are your favorite Herndon area spots?! There are so many good ones!
What does exposure really mean? That’s the question we tackled in a game during our recent Marketing & Visibility Training Session.
Two teams were tasked with creating a short commercial all about Cornerstone Defense—why someone should want to work with us. The catch? One team had significantly more time than the other. ⏱️
The results spoke for themselves: the team with more time had the advantage to showcase our company more fully, make a stronger pitch, and leave a bigger impression. And that was exactly the point—exposure is everything. You can have the best message in the world, but without visibility (or enough “time on the clock”), it won’t have the impact it deserves.
This exercise tied directly into the bigger conversation about social media today:
✅ How exposure helps our voices and careers grow
✅ Why organic engagement matters more than ever
✅ And how every like, comment, and share gives Cornerstone—and YOU—more visibility
It was a fun, eye-opening reminder that when we lift each other up and amplify our message, we all win. 🙌
🔥 Stay tuned—more highlights and key takeaways from this session are coming soon! In the meantime, if you’d like to learn more about working with us head to our site and navigate to our Culture page, or fill out a Contact Form to hear from us. We’d love to chat!
