About Us
Providing certainty to an uncertain world
Our Story
We are accountants who have a passion for serving. Our mission is to “Provide certainty to an uncertain world,” one client at a time. We enjoy helping people understand and solve their accounting and tax problems, which often cause worry and confusion.
We believe that a CPA should be an asset, not just an expense. Our goal is to provide lasting value to our clients through tax savings, advice, and education. We studied tax code for years to create strategies that help clients save money and keep it for themselves.
Elevated CPA was founded by Zach Roth, a Colorado native who wanted to provide Northern Colorado with a modern, full-service CPA firm. Zach holds a Bachelor's degree from the University of Northern Colorado and a Master's degree from Colorado State University, and is a Certified Public Accountant with years of experience in both public and private industry accounting.


In an industry constantly looking to cut costs by outsourcing work overseas or utilizing low-cost remote workers, we chose to be different. Our entire staff is local and works from our physical location in Windsor, Colorado.
