Just like the Blue Angels, our employee’s were celebrated in style on Saturday with a front-row seat to the Spirit of St. Louis Air Show & STEM Expo in our own back yard! ✈️

We were happy to bring together employees, families, customers, and partners for an exciting day of aviation, food, fun, and giving back!

Through CSI Cares, we supported the American Heart Association’s Stroke Division in honor of a longtime CSI technician whose journey continues to inspire us every day.

Thank you to everyone who joined us and helped make this year’s party one for the books!
