International law firm McDermott Will & Emery welcomes Shawn O’Brien to its Tax Practice Group as a partner based in Houston. Shawn is nationally recognized for his work on tax disputes and controversies with state, federal and international tax authorities.
“Shawn is a highly regarded, business-oriented advisor,” said Timothy Shuman, global head of McDermott’s Tax Practice. “He has become a trusted counselor to clients in many different industries, including energy, renewables and manufacturing. His work will further strengthen our unique tax controversy platform, which serves a full range of high-value tax issues facing our clients.”
