Founded by two of the original judges on the United States Tax Court in 1935, our decades of focus on the intricacies of the Internal Revenue Code and Department of Labor regulations have led numerous Fortune 500 companies, as well as smaller companies, tax-exempt organizations, and high net worth individuals to rely on us for answers to their most complicated and sophisticated tax planning problems as well as for complex tax litigation. Our experience has taught us that while the tax code is ever-evolving, for most taxpayers it remains dauntingly complex; we keep up on the latest developments in tax reform so that we can provide timely advice on how changes to the law will affect you and your business.

We believe our clients are best served by a practice environment in which lawyers concentrate on an area of specialization within the tax law, so that they see all the issues that come to the firm in that area.

We are committed to providing the highest-quality, timely responses to our clients’ needs. We also recognize an obligation to be forward-thinking and to bring potentially beneficial tax planning ideas to your attention, whether you're the Tax Director at a multinational corporation, or an individual taxpayer.
