We are DKC.
The principals of Devereaux, Kuhner &Co. LLP came together in 2010.
Yet, the partners and staff have been helping clients understand and navigate the sometimes confusing waters of business and personal accounting for decades.
What makes DKC different is its entrepreneurial spirit, dedication to client service, and passion for technical expertise.
Each member of the DKC team remains dedicated to creating a dynamic and collaborative workspace while staying curious, driven, and inspired.
Within our boutique firm, we have ten licensed CPAs, many professionals with advanced degrees, and others well on their way to earning additional academic honors.
Please meet DKC’s partners and staff below.
