International law firm McDermott Will & Emery is pleased to announce a significant expansion of its Miami Tax and Private Client presence with a six-member team including partners Mike Silva, Gregory Weigand and Arianne Plasencia, as well as counsel Ryan Coyle. These lawyers have extensive experience working with high-net-worth families and individuals. This expansion of the Firm’s growing Tax and Private Client presence in Miami advances the needs of its growing global client base.

“Our clients seek counsel bridging US and Latin American opportunities.

Mike, Greg, Arianne and Ryan are incredible additions to our team and we couldn’t be happier they chose to join McDermott.”

“McDermott’s Tax and Private Client teams consist of the best legal minds on the front lines of comprehensive and international legal changes. I’m thrilled to join this high-performing global platform and bring my experience into the mix on behalf of current and prospective clients,” added Mike.

William J. Butler, global head of McDermott’s Private Client practice, noted, “Mike, Greg, Arianne and Ryan’s work on the business ventures and tax requirements of high-net-worth individuals and families promises more significant and exciting collaboration with our growing private client team in Miami.”
