Our History

KDP Certified Public Accountants, LLP—a Medford CPA firm—was formed in 2014 when two well-established firms merged: Kosmatka Donnelly & Co. LLP and Michael L. Piels CPAs, LLP. Kosmatka Donnelly & Co. LLP formed in 1979 when Dan Kosmatka decided to purchase the Medford branch of his former employer, Deloitte Haskins & Sells, a “Big 8” accounting firm. Together with Dennis Donnelly and Michael Gohde, they grew the firm into one of the largest accounting firms in Southern Oregon—employing a full team of highly trained professional accounting and technical specialists. Michael L. Piels, CPAs LLP also began its existance in 1979 when Michael Piels opened his doors in Medford. He was soon joined by Stewart Parmele, Robert Hague, and most recently Mark Damon to form one of the most successful CPA firms in Southern Oregon.

Our combined expertise created a firm that provides all the services you need in one place: accounting services, audit and assurance, financial and business planning and advice, tax compliance and planning services, computer and Internet consulting, computer accounting services, and even financial services planning.
