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 appreciate the challenges and opportunities involved with developing the types of international tax strategies which allow companies to maximize centers of profit and growth. With growing domestic competition, Clayton & McKervey has observed a definite cost/benefit for our clients doing business overseas, and capitalizing on new and developing markets. 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.
