About Us

JCCS has more than 100 professionals working in seven locations. Yet we all share one goal: to guide you in making smart decisions today so you can have a better tomorrow.

With offices throughout Montana, JCCS is an accounting and advisory firm that looks beyond mere numbers.
Our clients are both big and small, individuals and businesses. But they all share certain traits. They have a vision. They understand the role a CPA can play in guiding their decisions. And they value insight, integrity, honesty, trust and accuracy. They find that here at JCCS.

Founded in 1946 in Great Falls, JCCS has grown to more than 100 professionals. Every one of them contributes to the community they serve – Great Falls, Hamilton, Helena, Kalispell, Missoula and Whitefish.

We’re an accounting and advising firm that’s about more than just numbers. Our goal is to keep you well informed so you can make sound decisions as you work to reach your short- and long-term goals. Our advisors deliver tax, audit and advisory services in ways that keep you moving forward.

We can collaborate with you on everything from managing payroll to paying the right amount of tax, from expansion plans like mergers and acquisitions to employee benefit plans, succession planning and valuation. To best serve your changing circumstance or current goal, we add in-house experts to your JCCS team as appropriate. When it comes to moving your financial goals forward, we firmly believe that knowledge is power
