TNDA: legal expertise, synergies and training for companies

The firm’s lawyers combine their skills and form multi-generational teams of partners and associates, to support companies, associations and their managers with discretion, responsiveness and the development of innovative solutions. Each client’s needs are taken into account by a complete team: back office, partners, associates, legal apprentices and successful trainees work together.

Since 2007, TNDA has added complementary skills in criminal law.
This department is currently headed by Karine Pérotin. Convinced that synergies and complementary skills serve the interests of its clients, TNDA has also developed a partnership in business law.

In 2025, TNDA’s partners created BERRI Formation and offer operational legal training in all areas of employment law. These courses are aimed at HRDs, HRMs, HRRs, company directors, executives, directors, lawyers and legal professionals.
