The Parlex Group

CLIENT: Jean-Sébastien DEGOUVE, Co-fondateur et Président
COMPANY/FIRM: Opéra Energie
TESTIMONIAL: Je savais que DELSOL Avocats connaissait bien le secteur de l’énergie pour avoir fait appel au cabinet lorsque j’exerçais des responsabilités au sein du groupe SUEZ (Engie). C’est donc tout naturellement que nous nous sommes à nouveau tournés vers Emmanuel KAEPPELIN lorsque nous avons eu des besoins en M&A.

CLIENT: Kal LADHA, Directeur Général
COMPANY/FIRM: MediaSchool Group
TESTIMONIAL: Dans le cadre de notre double activité, nous sommes fréquemment confrontés à des problématiques de droit du travail (collaborateurs permanents, intervenants occasionnels, journalistes …), de droit de l’immobilier (avec la nécessité de disposer pour nos écoles de locaux aux normes ERP – Etablissement Recevant du Public), de droit fiscal (notamment sur des questions d’exonération de TVA inhérentes à la formation) et de droit des sociétés (créations, fusions-acquisitions, transformations). Nous sommes très satisfaits, depuis plusieurs années déjà, de l’accompagnement de DELSOL Avocats et notamment d’Henri-Louis DELSOL, Séverine BRAVARD et Vincent GUEVENOUX dans nos opérations d’acquisitions successives, où la pertinence des conseils du cabinet dans des délais souvent très courts et la capacité des avocats à se glisser dans la peau du client entrepreneur nous furent précieuses tout au long desdites opérations et ce, pour le spectre complet des problématiques qui nous occupent

CLIENT: Nicolas POTEL, General Counsel, France & West Mediterranean Region
TESTIMONIAL: Nous travaillons avec DELSOL Avocats depuis plusieurs années et plus spécifiquement avec Stéphane PERRIN, qui connaît parfaitement notre entreprise, ses produits et ses problématiques juridiques depuis près de 30 ans. Nous avons établi avec lui un mode de fonctionnement sur mesure combinant réactivité et compétence. Cet
accompagnement est essentiel tant sur les contentieux du groupe en France que sur des problématiques contractuelles complexes.

CLIENT: Sophie DOSTERT, Directeur Général
COMPANY/FIRM: Hôpital Européen and Hôpital Saint Joseph de Marseille
TESTIMONIAL: Notre expérience récente confirme en tout point les grandes compétences de Xavier DELSOL et ses équipes, qui ont permis de rapidement mettre en place le cadre juridique du montage en passant en revue les différents scénarios possibles.
