  • ‘Dentons is a team which possesses unique knowledge in the local market. They have a trustable team which delivers on time with no fuss and maintains professional integrity throughout. They are trusted advisers and colleagues with whom I have worked with for years.’
  • ‘Tamsyn Mileham I cannot praise enough. Down to earth approach and self-assured manner gives trust and assurance to us and clients alike. A unique understanding of where risks lay and where to devote time and resource is a valued yet rare skill. TM does not aim to make herself 'look good' or is self-obsessed with an image or hard sell for the next project which sets her apart from industry peers. There is no wasted time or deliberation over inconsequential theoretical discussions. Her honesty is what has made us go back time and time again to work with her. She is a great coach, and I know for a fact that she cares about the development of her juniors, and this is evident with each transaction.’
  • ‘This practice stands out for its deep expertise, commercial awareness, and strong collaborative culture. The team is known for delivering high-quality, practical advice, often on complex matters that require cross-border coordination and strategic thinking. Clients value the accessibility and responsiveness of the lawyers, as well as their ability to work seamlessly across different disciplines and jurisdictions. Compared to other firms, this team offers a more integrated and client-focused approach, supported by meaningful innovations in technology, flexible billing, and a genuine commitment to diversity and inclusion.’
  • ‘The individuals I work with consistently stand out for their professionalism, clarity of advice, and genuine commitment to client service. They combine deep legal knowledge with a pragmatic, solutions-oriented mindset, which sets them apart from competitors. What I’ve particularly valued is their responsiveness, ability to anticipate issues before they arise, and the ease of working with them even under pressure. Stand-out partners like Tamsyn Mileham bring a strategic perspective that adds real value beyond legal execution, while associates such as Lara Battal consistently deliver high-quality work with impressive attention to detail and efficiency. The team’s collaborative style and proactive communication make them trusted advisers, not just legal technicians.’
