Get Customized IT Solutions to Drive Your Business

Twenty-six years ago, our service manager, Chuck, decided that he wanted to run his own computer repair company. He had seen the occupational, financial and even emotional damage that could be done by faulty, unreliable computers and realized how much good he could do with his natural problem-solving ability. He began working out of his basement and quickly built a reputation for his ability to repair computers.

As more and more businesses reached out to Chuck, he realized that he would not be able to give his customers the very best IT services while also handling the invoicing, receivables, taxes and other paperwork required to grow a business. That’s when CSU’s President, Michelle, became involved full-time. Michelle’s Business Management degree from James Madison University helped her to propel CSU to the next level and soon they were moving out of the basement and into the front running of competitive IT companies (and into an office!)

CSU’s humble beginning has reinforced our philosophy of keeping “yoU in CSU” by putting our customers first and helping them in any way that we can. As a small, family owned and operated business, we are able to have a more personal, one-on-one connection with our clients and that connection is something that we truly value. So, while the technology may have changed over the years, our IT company’s dedication to caring for our clients’ IT services so that their businesses can prosper has not.
