Greensphere Capital LLP
Margarita is a super intelligent and amazingly creative thinker who is able to find out-of-the-box solutions other lawyers cannot – and then perform them with surprising ease. She fully invests herself in every case she handles, an extremely rare quality of “living” the client's case that most other lawyers lack. Margarita's combination of talent, technical knowledge, experience and dedication to clients is truly unmatched. It was a great pleasure to work with her on a difficult multinational case, in the outcome of which she delivered an absolutely stunning result that was beyond everyone’s most optimistic expectations.
