SIGMA International and Global Market Attorneys

SIGMA was established by Cecilio Castillero in 2016 as a boutique transactional law firm practicing Panamanian law. Since its establishment, SIGMA has become the first Panamanian law firm specializing solely in complex transactions, including corporate and project financings, capital markets, mergers and acquisitions, joint ventures and infrastructure contracts. However, if the particular needs of a client or a transaction fall outside of SIGMA’s specialties, SIGMA will satisfy those needs by putting together teams of carefully selected Panamanian and international attorneys and organizing and supervising their work imperceptibly to the client.

SIGMA's s objective is to provide the highest quality legal services and solutions to its clients. SIGMA's motto ("In the business of solutions") highlights the firm's business-oriented approach. Under that approach, closing the particular transaction at hand becomes the ultimate goal that guides all decisions. SIGMA is in constant search for solutions to the obstacles that may stand in the way of that goal. This requires a creative and flexible mindset that analyzes those obstacles from the perspective of both the client and the client's counterparties, because no solution will be implemented unless it is agreeable to all participants in the transaction.

All of SIGMA's attorneys are fully bilingual in Spanish and English, and have experience working at large law firms in New York or D.C. In particular, SIGMA's founder worked for 10 years at Milbank in New York. Such experience is the basis of SIGMA's work-product quality, which is measurable by New York standards.
