Staff Profiles

Jeffrey R. Gentner, EA
For over 40 years,  my associates and I have been consulting and advising taxpayers on Personal Income Tax issues, preparing simple to complex tax returns for many each tax season. To keep the amount of tax paid to a minimum, I use all available adjustments, deductions and credits.  In late 2021, we moved to one central office location – 1961 Wehrle Drive, Suite 1, Williamsville, NY 14221 – to best serve all of our clients.
As an Enrolled Agent (EA), I am authorized to represent taxpayers before the Internal Revenue Service. Each year, to keep pace with the ever-changing tax laws and policies, I complete over 40 hours of Continuing Education, attending seminars and conferences both locally and nationally.
