Our Team

President & CEO

Todd has extensive experience in resolving civil tax matters at all stages of a tax dispute, including Internal Revenue Service (IRS) examinations, fast-track appeals, administrative appeals, post-appeals mediation and, if necessary, litigation in the U.S. Tax Court, the U.S. Court of Federal Claims, U.S. district courts, and U.S. Courts of Appeal.

The vast majority of Todd’s cases are resolved administratively and without becoming public. Nonetheless, litigation is sometimes necessary. A seasoned trial lawyer, Todd has a track record of winning difficult cases. Chambers describes Todd as an “excellent trial lawyer” who is “very effective” at handling tax disputes, and as a “go-to attorney for bet-the-company matters involving the IRS.”

Todd was named a Law360 “Tax MVP” in 2014, and in the same year the tax controversy practice that he chaired was recognized as the North American Tax Disputes Firm of the Year by Legal 500.  In 2015, Law360 recognized Todd’s victory in Schaeffler v. United States as one of the Biggest Federal Tax Cases of the Year.  In 2016, Law360 again named Todd a Tax MVP.  In 2018, Todd chaired McDermott Will & Emery’s Tax Controversy Practice when it was named the Tax Litigation Law Firm of the Year.  In 2019, Todd left McDermott Will & Emery so that he could focus his time and practice on select tax controversy engagements.
