CohnReznick, a professional services firm, acquired Houston-based Ham, Langston, & Brezina (HL&B), effective July 1, 2026. With three offices in the market, HL&B’s local expertise establishes an important expansion in Texas for CohnReznick and significant growth opportunity for the combined organization.
HL&B’s team of 12 partners and 87 employees brings to CohnReznick strong experience in energy, financial services, construction, non-profit and benefit plans. CohnReznick will leverage its deep advisory, assurance and tax resources in real estate, private equity, financial services, technology and consumer and manufacturing to serve the diverse and innovative greater Houston marketplace. CohnReznick’s existing presence in Texas includes offices in Dallas, Austin and a team in Houston focused on state government projects.
“Joining CohnReznick represents an exciting new chapter for our firm, our people, and our clients,” Rob Brezina, managing partner of HL&B, said. “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.”
This is the latest in a number of important expansion efforts that CohnReznick has made in the past year. The firm recently opened offices in Minneapolis, MN; San Francisco, CA; Tampa, FL; Denver, CO; and Tallahassee, FL; and Richmond, VA. Investing for organic growth and selective M&A opportunities have been successful strategies for the firm, now accelerated by its partnership with Apax Funds.
“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. “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 D. 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.”
