Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- The ONV LAW team has a strong ability to mix strategic insight with highly practical legal advice. The team demonstrated that it can handle complex, multi-stakeholder transactions and ensure seamless coordination among legal, financial, and operational aspects. We collaborated with M&A, tax, and public acquisitions teams, all working together perfectly. Their approach is client-oriented and solution-driven, which makes their advice both reliable and commercially sound. Their team strengths lie in their responsiveness, clarity, and genuine commitment to understanding our business model and strategic goals. Unlike other law firms that take a purely legal view, ONV LAW consistently adapts its advice to business realities, providing clear direction rather than theoretical analysis. The team also demonstrates innovation through flexible billing structures, efficient internal collaboration, and a transparent communication style that ensures predictability and trust. I must say that ONV LAW always offered the professionalism and expertise of a large international practice, combined with the agility and client focus of a premium boutique firm.
- They covered several projects over the past year, including corporate and commercial matters and M&A transactions. The team stands out through its solid legal expertise, pragmatic approach, and excellent understanding of our business. The lawyers I have worked with consistently demonstrated the ability to deliver clear, actionable solutions while keeping in mind our objectives for each specific project. I particularly appreciated their hands-on involvement, including at the partner level, throughout all project stages, and their effective coordination of teams to ensure timely, well-reasoned deliverables. In particular, I have worked with Sinziana Barbieru on our dispute and public procurement matters and Lorena Tanase, Bogdan Carpan, Ana Petrescu, and Mihai Pisica on corporate matters and M&A transactions. All of them distinguished themselves through their proactive approach and genuine partnership. The team combines strong legal rigor with excellent communication skills. Particularly, Sinziana Barbieru and Lorena Tanase have stood out for their meticulous attention to detail, exceptional responsiveness during critical stages of our projects, and remarkable ability to anticipate potential risks before they materialize. Their calm, knowledge, and solution-oriented approach and strong commercial awareness have consistently added value to the projects we worked on.
