“Before coming to CST Group we had worked with only one CPA, understandably we were concerned to start working with a group. However, the team at CST Group made the transition seamlessly. They are knowledgeable, professional, and friendly. They really know our business and they’ve helped us tremendously,” said Joy Anderson, President of JRA & Associates Contracting, LLC. “Our relationship with CST Group is very important to the operation of our business; it is critical that we have good financials in place in order to renew our lines of credit and increase our bonding capability. Our financials have improved since working with CST and we’ve been able to grow our business as a result.”
“We’ve worked with CST since our inception in 2011,” says Vital Edge Solutions COO David Lieberman. “When we first began, we needed assistance building our billing rates, ensuring all overhead costs, fees and fringes were included, and within guidelines. It’s clear the CST Group knows what it’s doing. We’ve never had to second guess anything,” Lieberman adds, “They are more like an extension of our team, not a separate company that we’ve engaged.”
