- 'The team is lean but highly focused, with partners like Julian Khorunzhiy and Ann Sydorovych directly involved in cases. They are responsive, collaborative, and not afraid to be creative when the situation demands it. Compared to larger firms, Ario offers more tailored partner-level attention and a culture of teamwork that clients find both efficient and reassuring.’
- ‘Ario feels much more agile. The partners are hands-on, always available, and they don’t just delegate the key issues. That direct involvement gives a real sense of confidence that nothing will slip through the cracks. What really makes Ario different is the way they combine heavyweight arbitration and restructuring know-how with a very down-to-earth, business-minded approach.'
- 'You never feel like you’re just getting a memo – you get clear options, risks explained in plain language, and a strategy that actually works in practice.’
- ‘Julian Khorunzhiy brings exceptional strategic vision and a rare mix of technical depth and commercial sense. In our case, he was personally engaged, not just supervising but actively shaping the strategy. That level of hands-on involvement is unusual among senior partners and gave us real confidence throughout the process.’
- ‘Ario’s dispute resolution team is known for handling some of the most complex and high-value disputes in Ukraine, many of which have a cross-border element. What makes them stand out is the mix of technical litigation expertise and a very practical, business-minded approach. Clients get clear strategies that look beyond the courtroom and take into account commercial risks and international enforcement.'
- ‘Julian Khorunzhiy is remarkable for his ability to look several steps ahead in a dispute. He combines a sharp legal mind with the foresight to design pathways that protect clients beyond the immediate case. His judgement is trusted because he is not only a lawyer but also a strategist who understands the wider commercial and procedural implications of each move.'
