Professional Focus – How I Can Help You

As a lifelong student of the US Tax Code, I am a problem solver and a protector of taxpayers’ rights. I lead a team of Enrolled Agents, Accountants, Bookkeepers, and Attorneys. Together we seek out and bring clarity to the U.S. Tax Code for all U.S. taxpayers.

As a Federally Authorized Tax Practitioner and a tax appeals specialist, I work for U.S. taxpayers everywhere to de-escalate stress and reconcile tax disputes for individual and business taxpayers.

Although I am not an attorney, my enrollment with the United States Department of Treasury under U.S. Treasury Circular 230 allows for confidential representation over most all civil tax matters.

I monitor federal and state taxing authorities and report on relevant tax topics in this well-subscribed tax blog using plain terms for general understanding – subscriptions are complimentary.

Industry Affiliations
