CohnReznick provides assurance, tax, advisory, and technology-enabled consulting services through CohnReznick LLP and CohnReznick Advisory LLC. Based in New York, the firm has approximately 5,000 employees and offices across the U.S., serving clients in sectors including government contracting, real estate, financial services, private equity, public sector, not-for-profit, and education. Its independent membership in Nexia connects clients to a global network of accounting and advisory firms.

The firm has continued to expand in areas tied to financial complexity, regulatory pressure, and public-sector funding needs. In 2026, CohnReznick entered Minnesota through its acquisition of Smith Schafer & Associates and launched a Public Finance and Sustainability practice focused on capital access, innovative finance structures, and sustainability goals for public sector and nonprofit clients. It has also added AI-driven analytics to its valuation advisory work, bringing more technology into financial advisory services that depend on speed, rigor, and defensible analysis.
