Spartan Tax Group

Brentley Leitzell is a Certified Public Accountant and the founder of Spartan Tax Group. A retired Coast Guard veteran, his service shaped everything about how he approaches this work — the precision, the accountability, and the refusal to cut corners.

Before founding Spartan Tax Group, Brentley gained experience in public accounting at a top national firm — and what he saw there stayed with him. Talented professionals, impressive resources, and clients who were treated like transactions. Every question had a price tag. Every phone call ran a meter. He knew there was a better way, and he built it. Spartan Tax Group exists because clients deserve a real business partner — not a service provider who disappears between billing cycles.

His experience spans the full spectrum — from individuals and small businesses all the way up to some of the largest corporations in the world. That range of perspective is rare, and it directly benefits every member of Spartan Tax Group. Whether you are navigating a complex business structure, managing personal investments, or facing a difficult situation with the IRS, you have someone in your corner who has seen it all.

Today, he leads a firm built around membership, not billable hours — serving business owners, entrepreneurs, and individuals across all income levels who deserve year-round guidance, not just a tax return once a year.
