A quick message to congratulate Marina and Dorine for their responsiveness in the face of my accounting ignorance 😉. I know that the 2024 balance sheet is complicated following the late opening of the professional account and the implementation of certain things. Congratulations to both of you

I would like to thank you warmly, as well as all the people who have done me a huge service in keeping my accounts, and of course Mr. François CATTIN in particular. I have indeed experienced difficult times in my professional and family life (and it still continues), but the quality of the exchanges, the quality of the services and the quality of the listening that this study has made available to me from the first contacts have been precious and comforting. I thank you especially for the quality of the human relationship that this entire superb team has offered me for several years.
