About us

L&S Registered Auditors was founded by Abdel Serghini and Saskia Luteijn, both of whom wanted to create a human-scale firm dedicated exclusively to auditing services, with absolute independence. This strategic choice is also based on the desire to offer services characterized by proximity, accessibility and an appropriate level of involvement of the partners in the audit work.

Thanks to this strategic positioning, our firm enjoys a high level of trust from its clients, who never feel that they are commercial targets for other services outside the profession of registered auditors. The relevance of this choice has also been strengthened by recent legislative reforms aimed at reinforcing the independence of registered auditors. In addition, our ratio of partners to associates enables us to : guarantee the total involvement of our partners in each assignment; promote a development strategy that encourages training; apply working methods that encourage the transmission of our skills, to the benefit of our clients and our teams; to to consistently emphasize the personalized approach of our work; and to offer our customers both a high level of expertise and continuity in each of our activities.
