I focus my practice on high-end litigation and investigations, including white-collar work and international arbitrations pertaining to commercial disputes throughout the United States and overseas. I have successfully represented clients in proceedings administered by many of the world’s leading arbitration bodies, including the International Centre for the Settlement of Investment Disputes (ICSID). My extensive business network in Turkey and the United States has trained me to tackle issues confronting clients from a global perspective.
