CohnReznick has acquired Houston-based CPA firm Ham, Langston & Brezina, effective July 1, expanding the top 15 accounting firm’s reach in Texas.
Financial terms of the deal weren’t disclosed. HL&B brings a team of 12 partners and 87 employees to New York City-based CohnReznick.
This is CohnReznick’s second M&A deal this year. The firm added Minneapolis-based Smith Schafer & Associates in January. Over the past year, CohnReznick has also expanded in San Francisco; Tampa and Tallahassee, FL; and Richmond, VA, after receiving an outside investment from private equity firm Apax Funds in early 2025. The outside capital is being used in part to spur investments in organic growth and selective M&A opportunities, CohnReznick said.

Founded in 1995, HL&B is an INSIDE Public Accounting top 300 firm by revenue. The firm provides accounting, auditing, and tax services to public companies, non-public companies and their owners, not-for-profits, and employee benefit plans, according to its LinkedIn page.
“Joining CohnReznick represents an exciting new chapter for our firm, our people, and our clients,” Rob Brezina, managing partner at HL&B who is now an assurance partner with CohnReznick Advisory, said in a statement on July 6. “We’ve built a strong reputation serving the Houston market, and by combining our deep local relationships with CohnReznick’s national platform and expanded resources, we are even better positioned to help our clients navigate complexity and seize new opportunities while creating new growth and development opportunities for our talented team.”
CohnReznick officials say the firm will leverage its deep advisory, assurance, and tax resources in real estate, private equity, financial services, technology, and consumer and manufacturing to serve the greater Houston marketplace.
The firm’s existing presence in Texas includes offices in Dallas, Austin, and a team in Houston focused on state government projects.
“HL&B’s strong talent, great client relationships, and industry depth complement our existing capabilities and will accelerate our ability to meet the needs of clients across Texas,” David Kessler, CEO of CohnReznick Advisory, said in a statement. “This combination advances our strategic growth in Houston, a key market for our firm, and expands our capabilities in energy, financial services, and real estate. Together, we are building a stronger, more connected platform to serve clients and drive long-term value.”
Allan Koltin, CEO of Koltin Consulting Group, who advised on the transaction, added, “CohnReznick has demonstrated a clear commitment to expanding in high-growth markets such as Houston, and the addition of HL&B enhances both its geographic footprint and industry expertise. It’s a compelling move that positions the combined organization for continued success.”
