Firm Overview

About Castro & Co.

International Tax Attorneys Serving Clients from Around the Globe

Founded in late 2007, just months before the global market collapse, Castro & Co. was forged in the market turmoil of the Great Recession of 2008. As revenues of companies around the globe plummeted, companies quickly realized that sophisticated international tax planning could substantially reduce their global effective tax rates. We are honored to have been a part of the plans of so many companies around the globe and to have been able to contribute to their success, which, in turn, has resulted in our own.

We Put Our Clients First

The hallmark of Castro & Co.'s success has always been and will continue to be the same: sophisticated international tax planning of the highest quality and results-oriented billing practices by superior attorneys who are proud of their profession. Each lawyer on our team does everything possible to solve our clients' issues with the utmost loyalty. Castro & Co. remains committed to prioritizing long-term relationships ahead of short-term profit goals. This commitment has allowed our firm to build close, lasting relationships with our clients.
