Catherine has been the Managing Partner at Karatzas & Partners since 1996. Before she worked with Shearman & Sterling in New York City from 1988 to 1992.

Catherine has always been in the forefront of legal developments and has participated and continues to participate in some of the most significant transactions for Greek economy and often for Greek national life. Recent examples include the Greek debt restructuring, the 15-year benchmark issue with the longest tenor that has been issued by the Hellenic Republic since the onset of the financial crisis, in 2009 a new, all-new-money bond whose maturity is longer than 2032, the year when the long-term relief measures for the Greek debt are expected to expire, as well as in the banking and financial sector the first recapitalization under the Bank Recovery and Resolution Directive in Europe, the first Greek Green bond and the first NPL transactions.

She was awarded the Pan-European award in the category of financial regulation in the International Financial Law Review Europe Women in Business Law awards in 2015 and entered The Legal 500’s Hall of Fame in 2018.
