Aaron Ressel
Founding Partner & Senior Controller
Aaron leads quality assurance and oversight at Debit & Co, drawing on 20 years building high-performing accounting teams. He reviews every client deliverable to ensure accuracy, GAAP compliance, and strategic value — turning good bookkeeping into Financial Clarity™.
His superpower is taking messy, chaotic books and systematically transforming them into clean, reliable financial data. When clients experience their “Month 2–3 breakthrough” and finally see real trends in their numbers — that’s Aaron’s work in action.
Aaron holds an MBA and spent two decades leading accounting and financial reporting functions — including a stint as Manager of Accounting & Financial Reporting at AgAmerica Lending — before co-founding Debit & Co with Kevin Cahill. He earned his undergraduate degree at the University of Central Missouri. That controllership background is why every engagement carries a senior review layer: nothing reaches a client without passing his bar for accuracy and GAAP integrity.
