Axylium Eupen

In 1993, the LLC “Bureau J. Souren” was established by Jeff Souren, who remained the sole partner until 2015 when Christelle Brouwers joined as a partner.

In 2023, the firm's name was changed to Axylium Eupen.

The fiduciary, approved by the Belgian “Institut des Experts-comptables et Conseils Fiscaux” (ITAA), primarily provides accounting, consulting, and tax return services for both SMEs and independent professionals.
