Tax Controversy Solutions

Our team of accountants, valuation experts, former tax practitioners, economists and data specialists approach tax issues by combining their broad perspectives on accounting, valuation and economics with their practical experience in academia, industry and prior testimony.

In addition to our involvement in the largest tax litigation matters in US history, we work with outside counsel and taxpayers to proactively address complex tax issues and strategize on methods to resolve potential disputes during exam.
