Lisa Brown
CEO & Founder
I’m the CEO and Founder of CST Group Inc., which I started in 2000 with one clear goal: to help businesses and local government organizations resolve technology challenges so they can stay focused on growing and serving their communities.
Early in my career, I saw firsthand how overwhelming technology and cybersecurity requirements could be—especially for small organizations without the right guidance. That experience shaped my passion for ensuring every client receives the expertise, advice, and resolution they truly deserve.
I help clients by providing peace of mind. When technology is handled the right way, it becomes a support system instead of a stressor. I’m passionate about what I do, and yes—my excitement sometimes shows a little extra. I see it as a strength and a reflection of how deeply I care about our clients’ success.
Outside of work, family is my favorite “hobby.” I love spending time with my kids and grandchildren, golfing, and being out in nature. I’m committed to delivering outstanding technology services so our clients never have to worry about what’s happening behind the scenes.
