Isabelle has been consistently recommended for over 20 years as an expert in EU competition law matters by Chambers Europe and Chambers Global, in particular for her business-minded and practical approach to finding legal solutions for clients. Chambers Global 2022 reports that Isabelle is valued by clients for her flexibility to handle both specific instructions around merger filings and ongoing questions relating to competition compliance. "She gets straight to the point, raising interesting facts that might be relevant for our business and proactively advising us on issues," says one source. "She knows exactly how to position her input," states another interviewee, while a third client notes: "She is willing to take a clear position on an issue and come up with a practical solution that we can really use in our business." She has also been recommended by European Legal Experts, Practical Law Company (PLC) and The Legal 500 EMEA, which noted in their 2022 Guide that 'Isabelle gives top-notch advice with a first class client service and approach'.
