SIGMA INTERNATIONAL AND GLOBAL MARKET ATTORNEYS was established by Cecilio Castillero as a boutique transactional law firm. SIGMA’s clients are Panamanian and international businesses, entrepreneurs, executives, high net-worth individuals, family offices, financial institutions and advisors engaged in business and all types of transactions. The firm’s objective is to provide the highest quality legal services and solutions to its clients, in particular in the areas of debt and equity financing, mergers and acquisitions, regulatory matters and joint ventures. However, if a client’s needs exceed SIGMA’s in-house capabilities, the firm will reach out to selected attorneys and other service providers in order to form the best possible team to satisfy those needs.
The firm’s culture is one of responsiveness, with a singular focus on promptly addressing the clients’ legal needs with practical and efficient solutions. The firm is born with the goal of creating a professional environment that promotes teamwork and close collaboration between its attorneys and staff for the benefit of the firm’s clients.
