Rey is a tax transactional and controversy attorney who supports clients’ tax needs, from corporate deals to private wealth to litigation.

Rey advises clients on tax matters on a variety of U.S. and international business transactions, including mergers, acquisitions, spin-offs, reorganizations, joint ventures, and estate planning for high-net-worth families.

A former political science graduate with a passion for U.S. politics and democracy, Rey discovered a passion for tax law early on in law school. He was fascinated by the variety of legal recourse capabilities with respect to tax policy, as well as by how the discipline was embedded within each branch of the U.S. federal government, causing him to pursue a Master of Laws degree in taxation.
