- ‘It is a leading department in its field. Its members possess a high level of technical and interpersonal skills, a perfect combination for navigating extremely complex business situations. Their availability and customer service are second to none, and their teamwork is absolutely impeccable.’
- ‘For me, one of the key people in this practice is Laura del Barrio Aranda. Trained at top-tier institutions and with over 15 years of solid experience in Restructuring and Insolvency, she has strengthened the department and taken it to a higher level since joining the firm more than three years ago. Her ability to solve problems quickly and effectively is her defining characteristic. Furthermore, she is always present when complications arise, and her availability throughout the entire process is exceptional. Always proactive and seeking the best solution for clients, she is one of the best assets not only of the department but of Ontier as a whole.’
- ‘My experience working with the ONTIER team has been so intense that, after some time, I've come to understand why this law firm is number one in Spain. There are several reasons. While it's true that, when working with a firm of this calibre, all practices related to restructuring and insolvency are covered by other departments, the extensive knowledge of its partners translates into clear cost efficiency for the client. It's worth noting how its partners, in addition to their vast experience in Restructuring and Insolvency, bring multidisciplinary knowledge that fosters trust through peace of mind and efficiency.’
- ‘In the area of restructuring and insolvency, this firm stands out for its extraordinary and exceptional ability to empathise with and reassure clients in extreme professional and personal situations. I believe that this common denominator of technical and practical excellence, comprehensive vision, and ability to build trust is a result of the senior management's success, which has also extended to the selection of personnel.’
- ‘Extreme knowledge, negotiation skills, strategic ability... Bernardo Gutiérrez and María Luisa Tortosa were particularly outstanding.’
- ‘María Luisa Tortosa is an exceptional lawyer due to her technical knowledge and her dedication to serving external clients.’
