GST LLP, an international dispute resolution boutique ranked among the Top 100 International Arbitration Firms in the world, announced that three associates have been promoted to counsel and senior associate positions amid continued growth and increased demand for the firm’s legal services.

Katherine Sanoja has worked with the practice, including its predecessor for eight years.

She is also a highly engaged member of the Miami community, dedicated to local arts and culture organizations as well as human and civil rights causes.

Promoted from Associate to Counsel, Pablo Mori is based in the firm’s headquarters in the District of Columbia. He will help lead and manage GST’s Spanish-language practice, including disputes in Peru, Colombia, and Honduras. Given his distinct familiarity with the Peruvian market, Pablo is set to spearhead case efforts in the country expanding upon the firm’s dominance in the region. In the last 12 years, Pablo has represented private and State entities in various arbitration proceedings seated in the USA, Latin America and Europe, including disputes valued at over US$5 billion.

Rounding out the recent group of promotions is Gary Shaw, named Senior Associate.
