Welcome! CPA Group of The Rockies, formerly Ruesch, Biddle, Larson, & Ratliff, CPAs has over 120 years of collective CPA experience. It’s not about the number of years though – it’s our depth of knowledge and commitment to proactively enhance your situation no matter the tax law updates and/or regulatory changes. Simply put, we provide you the focused attention you’d expect from a solo practitioner, with a team of professional experts you’d expect to find at a much larger firm.

Our roots run deep in specializing in agriculture for the Northern Colorado community, but our expertise has expanded to cover every individual and small business client’s needs. Over the past several years, we’ve been carefully evaluating our proficiencies and the areas where we can provide the most value to clients like you. We look forward to earning your trust and confidence if there is a fit between what you are seeking and what we provide.

“My CPA only talks to me once a year and I’m lucky if I get 30 minutes of their time. I’m simply not getting the proactive tax and business planning I had hoped for.” Does this sound familiar? Yeah, we’ve heard it a time or two before.

We’re here to change the narrative! We start with one question: What would you most like to improve, develop, or change in your financial life? Then, we help you chart a successful path forward to alleviate those pain points. Often, those solutions include our dedicated efforts in simplifying your tax, accounting, business, and financial needs.

How would proactive tax, accounting, and cash flow advice change your future? It’s changed our clients’ lives. We look forward to being a small, yet meaningful part of your family’s story.

Let’s Talk

Our History

1973

William R. Ruesch (Bill) founded our firm to serve many Northern Colorado families and small businesses. He specialized in providing tax and accounting solutions for folks in the agricultural space.

1992

The Ruesch & Biddle, CPAs, LLC partnership was established in Greeley, CO. The two CPA members, Bill Ruesch and Marsha Biddle, are still with us today to keep us all in line!

2002

Lance Larson, CPA, joined our team in an effort to enhance our collective knowledge and provide services to more folks in our community. Shortly thereafter, Lance became a member and our name changed to Ruesch, Biddle, & Larson, CPAs, LLC.

2006

Ben Ratliff, CPA, came onboard to bolster the operations and provide multi-generational continuity for our business. In 2011, he also became a member, which meant the name on the door became longer: Ruesch, Biddle, Larson, & Ratliff, CPAs, LLC.

2023

We rebranded to CPA Group of The Rockies with the same familiar faces and a couple new ones. Our reinvigorated focus and professional team are here to provide you with a more complete client experience – all while honoring the legacies of those who laid the foundation.
