More About CP&A Our Leadership
We're Always Expanding

Our greatest strengths lie in overcoming the challenges presented by a dynamic market. As Casey Peterson and Associates has watched its clients evolve with the developing community, a similar transformation has taken place within its very own personnel and physical workspace. Time and progress has populated our workforce to nearly fifty employees and two locations. Our expansion as a company has taken our services to a second office of CPAs in Gillette, Wyoming, and spread the Casey Peterson and Associates reputation into the farthest reaches of the region.

In addition, the 2011 relocation of our Rapid City accounting firm from its original downtown office space to the first floor of the Turnac Tower is a prime indicator of our growth and accomplishments. We invite you to stop in at our new home and sample the refinement of our state-of-the-art surroundings.
