Our story began when James Vollmer, a Fanshawe College graduate in Business Administration – Accounting, was invited by Business World to manage personal and corporate clients. Starting as an independent contractor, James applied his expertise in personal and corporate tax, filling an important gap in the company’s services. Following the retirement of the original owners and the acquisition of their clients, J.M.J. Accounting & Tax Services Inc. was incorporated in March 2010.
