As an international tax advisor, Sue helps businesses structure their operations globally to mitigate tax costs and maximize profits.

What is your area of focus?

I work with clients on international tax solutions, working collaboratively with accounting and tax specialists around the globe through our affiliation with PrimeGlobal.

I lead a team that works directly with these types of business owners, providing recommendations on how to best structure operations globally to mitigate tax costs.
