Who we are

Numbers tell stories. We help you write a better one.

For more than fifty years, Katz Abosch has stood beside the closely-held businesses, families, and institutions that shape the Mid-Atlantic.

We pair the discipline of a top-100 CPA firm with the responsiveness of a partner who picks up the phone. Whether you're navigating succession, expanding across borders, or just trying to close the books with confidence, our teams build durable plans grounded in the realities of your industry — and your appetite for risk.

That's the work. That's why our clients stay for decades.
