The assurance of quality service

BLL Consulting becomes BLL Academy by Kaufhold & Reveillaud

BLL Consulting, was founded in 2019 by Sandra BIRTEL following her previous professional experience, well aware of the lack of training among experts in the field and above all the lack of information and support offered to smaller structures. One of the structure’s major projects was to create the BLL Academy, the first training platform dedicated to regulatory issues, which now includes the law firm Kaufhold & Reveillaud, of which Sandra, who became a lawyer a few years earlier, is a partner.

This logical evolution has enabled us to offer our customers an even wider range of services, but always with the same passion.
