Meet Josh Tonnesen - Owner & Founder

As a CPA who streamlined financial reporting at Hertz, built executive dashboards at Arthrex, and created CEO reports at Aztec Industries, I've analyzed thousands of financial statements and automated complex consolidations.

After cutting corporate headcount by 50% through process improvements and mastering PowerBI analytics, I founded Tonnesen Accounting Services to bring this Fortune 500 expertise to small business owners.

Having guided 150+ transactions and developed specialized quality of earnings workbooks, we ensure you have institutional-level financial analysis for your most critical business decisions.
