Lumsden & McCormick is proud to be one of the largest certified public accounting firms in Western New York. Begun in 1952 by Stewart H. Lathan and Charles L. Lumsden, the small Buffalo, NY accounting office was joined a few years later by Richard B. McCormick. Then known as Lathan, Lumsden & McCormick, we have since enjoyed tremendous growth as a Buffalo CPA firm, becoming what is known today as Lumsden & McCormick, LLP.

Being a CPA in NY, our clients represent closely held and publicly held businesses, individuals, nonprofit organizations, governmental entities, and municipalities. We provide a wide range of services including auditing and accounting, corporate and personal tax planning, international taxation and financial planning.

A wholly-owned subsidiary of the CPA firm, Brisbane Consulting Group, LLC, has provided business valuation, litigation support, merger and acquisition, forensic accounting, and computer technology services since 1996.

In 2000, we expanded our services yet again to include investment management through the creation of Lumsden & McCormick Financial Services, LLC. We assist individual and corporate investors and employee benefit plans by providing diversified investment options.
