    I am fortunate to be able to successfully represent our clients before various courts and administrative tribunals, particularly in the context of complex commercial disputes and injunctive relief, including breach of non-competition clauses, non-solicitation and unfair competition.

    In addition, I advise our clients in order to assist them in the implementation of regulatory compliance programs in companies.
