- COSRO is a dedicated and professional law firm. I am always in awe that their commitment is so full. Partners keep us in the loop on important decisions in Brazil that could affect our business and our capacities to work within the country.
- Bruna Rocha is incredible; she is always available and so keen on working alongside us.
- The firm stands out in the national legal market for its combination of technical excellence, in-depth knowledge of the healthcare sector, and a highly results-oriented approach focused on strategic client outcomes. The team possesses solid experience and specialization in healthcare, including health regulation, market access, compliance, and interaction with agencies such as ANVISA and CONITEC. This in-depth knowledge allows not only for a precise interpretation of the regulatory environment but also the ability to anticipate risks and opportunities, strategically aligning legal recommendations with clients' business priorities and objectives. One of its main differentiators is its ability to act as a strategic partner, not just a traditional legal advisor. The team understands the broader context of business decisions and, therefore, can translate complex issues into practical, viable recommendations aligned with the competitive environment, ensuring real impact for the organization.
