What makes the practice unique is that you feel at ease right away. You feel confident because of the level of expertise. The team is not looking down at you. You are treated with respect and sympathy. You are clearly with a partner embarking with you in your case rather than a sub-contracted service you are obliged to deal with. You receive clear and understandable information about your case. Much appreciated.

Kadrant is extremely client-focused and takes the time to fully listen to the client and understand its needs. They are extremely competent and helpful to propose solutions.’

Giulia Mauri and Mériem Bennari both really put in the hours to provide us with great service. They are a great team and it never feels like the senior partner is absent or delegates to the associate. From the initial meeting, Giulia has been excellent and has helped navigate some difficult situations. They both bring dynamism to their work and as individuals they take pleasure in their work and it shows.

The team is highly complementary so that they can answer very quickly any specific question asked. Whenever the team does not have the answer internally, as it has developed a wide positive and trustful network with a range of other professionals, readily passes on the contact details or introduces the issue. They never let you down.

Everyone is extremely kind, always calm, understandable and replies immediately, as everyone understands the urgency of the matters. It is also nice that the individuals in the firm know transversally about each other’s major clients and so they can address urgencies whenever necessary or direct clients to the right staff.

Team is small and focused, they are not (or at least they don’t give the impression) looking for new customers, but instead make you feel like a partner, or even a colleague.
