“Over the years we have worked with CST Group, we have been extremely satisfied and happy with the work they have performed for us,” says GovSource Principal Eric Tedder. “Their vast knowledge of extremely complex IRS codes, compliance regulations, and issues facing government contractors is unmatched. It is through their knowledge, ability to stay ahead of ever-changing protocols, and dedication to our firm that CST Group has been able to save us immense amounts of time and money. Their team is not only professional and responsive, but they are great to work with on a personal level as well.”
“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.”
“We have developed a unique and collaborative relationship working with CST Group over the past 15 years,” says Cassaday & Company Principal Christopher Krell. “What stands out the most to me is just how much CST Group’s people—from the firm’s leaders to the staff accountants—care personally about our well-being. They really have a passion for what they do and provide an incredible level of service to their clients. CST Group has a tremendous depth of expertise and resources, yet they maintain the right personal touch with a level of responsiveness that is second-to-none. Our clients who have worked with CST Group have had a unanimously positive experience.”
