- What we value most about the lawyers we have worked with is their availability, responsiveness, and knowledge of the regulatory and contractual environment in the energy sector. They have a strong ability to understand technically complex issues and translate them into clear legal and commercial implications. I would also highlight their practical approach. Instead of simply identifying risks, they strive to understand the client's business objectives and propose alternatives that allow for a sound legal path forward. In particular, Sebastián Saa Tamayo stands out for his legal judgment, his ability to quickly grasp the context of matters, and for offering a practical, decision-oriented perspective. His involvement inspires confidence when it is necessary to evaluate alternatives, risks, and potential courses of action. Lisseth Armijos also stands out for her legal expertise, analytical skills, and understanding of the regulatory and contractual context. Furthermore, we especially value her availability, close follow-up, and ability to coordinate among the various parties involved. She combines sound legal judgment with a proactive attitude and a clear understanding of the client's business needs, which facilitates efficient progress in complex matters.
- Spingarn stands out for combining solid legal expertise with a deep understanding of the energy sector and the commercial aspects of projects. The team quickly grasps the client's context and goes beyond simply providing a strictly legal interpretation, helping to identify practical alternatives that allow projects to move forward while maintaining adequate risk management. In our experience, they have been particularly helpful in matters related to contracting, bidding processes and public procurement, document review, and legal support for international projects. We also value their ability to coordinate with various stakeholders, including clients, partners, and public entities. Communication is direct and professional, and the team responds swiftly, even under tight deadlines. From our perspective, this combination of legal knowledge, commercial acumen, and availability sets Spingarn apart.
