Jason Thompson

Firm Owner

I've spent the past 20+ years helping business owners, finance professionals, and accounting teams work smarter. As a CPA with experience across public accounting (Big 4), private industry (Internal Audit at $5B AgriBusiness Private Company and Controller for seven entity $30M Holding Company), and the vendor side (CCH, Wolters Kluwer, Botkeeper, Work 365) and my own firms (TC&CPA Services and Holistic Advisors), I've seen firsthand how the right systems, workflows, and tools can completely transform how businesses manage their financial operations.

Throughout my career, I've partnered with small and large businesses and finance leaders to streamline accounting processes, implement technology that actually works for them, and build stronger, more efficient operations. My passion lies in bridging the gap between operations and accounting: helping people simplify the complex and focus on what truly drives results and matters most to them. I also have extensive experience in software sales and building and leading elite teams. I hold a Certificate in Leadership Principles from Harvard Business School Online.

Reading, running, live music, service work, family and friends are what occupy my free time. Let's meet!
