Tulsa, Okla.-based IPA 100 firm HoganTaylor LLP (FY24 net revenue of $75.83 million) has expanded its footprint in Louisiana through a merger with Hawthorn Waymouth & Carroll LLP (HWC), a Baton Rouge-based accounting firm, effective January 1, 2026. Following the merger, HWC began operating under the HoganTaylor name.
Founded more than 70 years ago, HWC has served individuals and organizations across Louisiana, providing audit, tax and accounting services. HoganTaylor first entered the Baton Rouge market in 2023 with Louisiana professionals who brought more than 50 years of combined experience serving clients in the state.
“The Baton Rouge market aligns well with who we are as a firm, and the city’s culture reflects the communities where we have been successful,” said Todd Wisdom, growth partner at HoganTaylor. “Clients appreciate local relationships backed by the resources of an independent regional firm. HWC’s long-standing presence, combined with our broader platform, makes this a strong match for both firms and for the Baton Rouge community.”
The merger adds Brittany Thames and Kevin Rodriguez as assurance partners, along with 10 additional professionals, bringing HoganTaylor’s Louisiana team to 16. The combined office is operating from HWC’s former location on United Plaza Boulevard.
“Building this firm alongside our team and clients has been one of the great privileges of my career,” said Louis C. McKnight III, MP of HWC. “As HWC joins HoganTaylor, I know we are placing that legacy into hands that share our values, our commitment to excellence and our belief in doing what’s right for the people we serve.”
HoganTaylor operates offices in Tulsa and Oklahoma City, Okla.; Little Rock and Fayetteville, Ark.; and Baton Rouge, La., and ranks No. 77 nationally among accounting firms according to INSIDE Public Accounting.
“Clients in Baton Rouge will see continuity where it matters most,” said Tabatha Broussard, MP of HoganTaylor’s Baton Rouge office. “They’ll keep working with the people they know and trust, but with the backing of a firm that understands their market and offers broader resources to support their goals.”
