How Jason is building a better working world

International tax is one of the most complex areas to practice in, but I love breaking it down so that even people who are new to the area can understand it. International tax has become incredibly dynamic in recent years, and I am passionate about mentoring and developing a new generation of international tax lawyers who are willing to challenge traditional ways of thinking in order to keep up with an ever-transforming global tax environment.
