In recognition of her work, The Legal 500 US (2020) recently named Ms. Sinisterra a “Rising Star” in the field of international law—a distinction that she alone held in that particular guide, where she was notably praised for her “tremendous capacity to assimilate huge amounts of complicated and diverse information and work tirelessly to formulate a legal argument.” Ms. Sinisterra was also recently named a “Rising Star” by The Legal 500 Latin America (2021) and was recognized as a “Future Leader” in international arbitration by Who’s Who Legal (2020 and 2021). The guide describes her as a “superb lawyer” who is “extremely talented” and a “top choice for disputes in the oil and gas and construction industries.”

Ms. Sinisterra joined Debevoise in 2014. She received an LL.M. from Harvard Law School, where she was a recipient of a Dean’s Scholar Prize and a member of the Harvard International Law Journal. Ms. Sinisterra received her Law Degree from the Universidad de los Andes in Bogotá, graduating first in her class. During law school, she participated in an exchange program with Notre Dame University and received a degree, magna cum laude, in Advanced Social, Economic and Political Studies.

Prior to joining Debevoise, Ms. Sinisterra worked in the arbitration group of a large international law firm based in Paris as well as the international disputes practice of a well-known Colombian law firm.
