Testimonials
Collated independently by Legal 500 research team.
- Victoria Demarchi, the primary point of contact, embodies the firm's hallmark: she provides support, maintains constant follow-up, is fully aware of the case details at all times, and fosters a genuine closeness with the client that is uncommon in firms of this caliber. There is no hidden delegation or gradual distancing as the case progresses. Rodrigo Gil demonstrated the same level of expertise and commitment in our interactions with him, confirming that quality doesn't depend on a single individual but is a team-wide effort. This was clearly demonstrated when Victoria Demarchi was unable to attend a meeting with the opposing party: she ensured that Rodrigo Gil represented her, and he did so with complete understanding of the matter and without any disruption to the client. This experience generated absolute confidence.
- The firm’s hallmark lies in its personal and unwavering commitment to every case it takes on. For example, in a market where excessive delegation is common practice—and a frequent source of client frustration—partner Victoria Demarchi represents the exact opposite: presence, follow-up, and in-depth knowledge of the case at all times and in every stage. Victoria Demarchi also combines a friendly and genuinely concerned approach to the client with the technical rigour that complex matters demand. Her follow-up is not reactive—she doesn't wait for the client to ask—but proactive and constant. The team's associate lawyers are equally outstanding, but what truly sets this firm apart is that the senior partner is always present: the client always has someone who understands their case. Compared to the competition, this combination of technical excellence, personalized service, and a genuine lack of delegation is the most difficult differentiator to match.
