« Our customer relations are mostly about interpersonal relations »

To practice as a chartered accountant one must first and foremost be an effective listener, i.e. have the ability to listen before proposing solutions.
Our customer relations are mostly about interpersonal relations. In fact, “client” is not really the right word; “partner” would be more appropriate. It’s like in tennis – you need two to play the game.
Without our partners, we cannot do much; with them, we can aim for the very top.
Our distinctive ability to provide long-term support based on trust and loyalty have led to some great economic success stories. These success stories are not ours, but we helped make them possible through our presence and advice.

Our intrinsic qualities based on loyalty and trust have enabled us to develop close ties with companies whose financial statements we certify.
The stability and loyalty of our teams are key factors in our relations with our clients.
By applying the best methods to suit the needs of each company, we bring added value at the human level.
Our best reward is the renewal of our term of office when it expires.
Our pride: since several years, they have all been renewed.

The audit and chartered accountancy practice is becoming increasingly regulated. Our professional ethics guarantee both our independence and our professionalism. Our approach is however unique. While complying with our ethical rules, we are at the service of our clients, supporting them in their growth and in their difficult moments. By offering a customised service, we create a partnership that meets your specific needs. Drawing on our close customer relations, we strive to make you unique.


Following 7 years [1975-1981) experience with a chartered accountancy, audit and legal expertise (Court of Appeal and Court of Cassation) firm operating at the national level (the head of the company was the Chairman of the Court Experts of France), Didier HASSAN created his own Chartered Accountancy and Audit Firm located in the 15th district of Paris at the beginning of 1982. To cope with the rapid development, the firm was relocated to more spacious premises in Paris, in the 17th district (600 m1), dedicated to Chartered Accountancy and Audit.
In 2005, in the face of growing demand, the Firm shifted to its current more appropriate premises at Parc Monceau and consolidated its specialisation and specific expertise in Audit. As regards its accounting services, it only kept its historical clients mainly specialising in services.
