Doeren Mayhew, a US-based assurance, tax and advisory practice, has announced a merger with Atlanta-area company AGL CPA Group, marking its expansion into the Atlanta market.
AGL CPA Group, which now operates under the Doeren Mayhew brand, serves a diverse clientele that includes closely held businesses and high-net-worth individuals, providing consulting, tax and attestation services.
The merger brings more than 20 employees from AGL into Doeren Mayhew.
Jay Robbins has been appointed as managing principal for the region, with AGL partners Bradley Sienkiewicz, Jim Leutenegger, Justin Bailey and Daniel Cassandra joining the company’s leadership team as principals.
Doeren Mayhew CEO Chad Anschuetz said: “Finding the right strategic partner in the Atlanta community was an important part of our vision for growth in the south-east.
“AGL’s established presence of reputable work and technical expertise will accelerate our growth trajectory in this pivotal international hub.
“We are excited to welcome the AGL team to the Doeren Mayhew family, and we look forward to serving the local community with them by our side.”
This transaction establishes Doeren Mayhew’s presence in Atlanta with a new office in Duluth and enhances its capabilities across several practice areas including audit, CFO advisory, construction, manufacturing, professional services, real estate, tax and transaction advisory.
The practice aims to leverage AGL’s expertise in technology, broker-dealer and alternative investments to broaden its industry reach.
This merger represents Doeren Mayhew’s sixth addition in 2025, following its expansion into Nashville through the acquisition of Thurman Campbell Group in March.
AGL co-founder and managing partner Bradley Sienkiewicz said: “We are thrilled to join Doeren Mayhew. Culture was the most important factor in finding a partner to grow alongside.
“Doeren Mayhew shares a common culture of excellence, great people and bullish vision for the future. Combining forces seems like a natural progression for AGL.
“It gives us the dynamic platform to provide expansive resources and solutions to our clients, while providing unparalleled career opportunities to our team.”
Alan Koltin, CEO of Koltin Consulting Group, who advised both firms on the combination said: “Expanding into the Atlanta market was a high priority for Doeren Mayhew, and they found the perfect firm in AGL! AGL is young, entrepreneurial and has a great reputation in the technology space.
“Doeren Mayhew has had significant success in executing on its M&A and lateral talent strategies.”
