NATIONAL PRESENCE. 

“SMALL TOWN” FEEL.

Our consulting practice traces its history back to 1988 when a young Tom Grottke was a consultant at Arthur Andersen. There, he met Mark Shaw, who served as CIO of a community bank that Tom was working with, and the collaboration between the two began.  While following separate career paths the two maintained business relationships until 2010 when Mark joined Tom’s new financial institution consulting firm – today known as The NBS Group.

In 2018, The NBS Group was integrated into Crowe, LLC and the services provided to financial institutions were enhanced and delivered on a national scale.  In early 2023 Mark and Tom emerged from Crowe and on April 1, 2023, reformed The NBS Group bringing key talent with them while adding to the team.

In November 2023, The NBS Group expanded its leadership with the addition of Steve Nickolson.  A veteran of the industry, Steve provides complimentary experience and vision to NBS enabling expanded services and greater client satisfaction.

Tailored Combination of Strategy, Technology, and Performance Improvement Services.
