CliftonLarsonAllen LLP (known as CliftonLarsonAllen or CLA) is a professional services network and the eighth largest[1] accountancy firm in the United States. It was established in 2012 when two top 20 U.S. firms merged: Clifton Gunderson LLP (based in Milwaukee, Wisconsin) and LarsonAllen LLP (based in Minneapolis, Minnesota).[2] It is a member of the Nexia International accounting network.[3]



It was the 14th largest accounting firm in the US in 2010,[4] and the largest member firm of HLB International until it left that network in 2012 after the merger with LarsonAllen.[3]


In 2009, LarsonAllen was named a Best Place to Work in Charlotte,[5] Minneapolis, Philadelphia,[6] Phoenix[7] and St. Louis [8] by local business journals, and the firm’s learning and development team was honored by the American Society for Training & Development (ASTD).[9]


Merger discussions between Clifton Gunderson and LarsonAllen commenced in the spring of 2011 and progressed rapidly, so that in the fall of that year they announced plans to merge the two firms. The merger occurred January 2, 2012. The decision to affiliate to Nexia rather than HLB International was taken after the merger.[3][10]

CliftonLarsonAllen emphasizes industry-specific services, as well as a focus on privately held companies and their owners, nonprofits, and governmental entities.[11] Accounting Today reported speculation that the merged firm may expand into public company audits.[10]

Kris McMasters and Gordy Viere became the first co-CEOs of CliftonLarsonAllen LLP,[12] with Viere also serving as the CEO of CliftonLarsonAllen Holdings.[13] McMasters retired April 1, 2013, leaving Viere as sole CEO.[12] Denny Schleper became the CEO of CliftonLarsonAllen in January 2015 after Viere retired. [14]

In September 2013, CliftonLarsenAllen agreed to pay a $35,100,000 settlement on the audit of the City of Dixon. CG had performed the audit for many years but failed to recognize a $54,000,000 fraud.[15] In addition, the firm was fined by the Illinois Department of Financial and Professional Regulation.[16]

Offices and personnel[edit]

CliftonLarsonAllen employs more than 5,400 people, including more than 700 principals and 2,300 CPAs, in more than 110 locations across the United States.[17]
