John represents large publicly traded and privately held businesses in controversies, transactional matters and tax planning involving state and local corporate income/franchise taxes, gross receipts taxes, sales and use taxes, and other business privilege taxes. He also defends clients in state tax audits and litigation before courts, administrative agencies and departments of revenue throughout the country.

In addition to his state and local tax practice, John is also one of the nation’s leading attorneys in the emerging field of state unclaimed property laws. He represents clients in multistate unclaimed property audits, litigation, voluntary disclosure matters and complex transactions. His unclaimed property clients encompass nearly every industry, including manufacturing, health care, and technology. While each client’s circumstances are distinctive, his primary concern in every matter is helping clients determine whether their business operations are producing unclaimed property liabilities and finding ways to restructure those operations to minimize unclaimed property exposure.

John is adept at simplifying challenging tax circumstances for his clients. He has developed a reputation among them for his hands-on representation style and willingness to go above and beyond to resolve matters quickly and efficiently. He also possesses a singular ability to analyze complex issues thoroughly and develop creative strategies that put clients at ease when litigating tax matters.

John currently serves as Chair-Elect of the American Bar Association Section of Taxation’s State and Local Tax (SALT) Committee.
