Our History

A decade of excellence
in the Principality

MCA Assessors was founded in 2013 by Marc De Diego Ferrer with one conviction: high-net-worth individuals and international entrepreneurs deserve guidance that matches their ambitions, within an exceptional tax and legal framework.

Over a decade, the firm has become the reference for Francophone and international clients establishing themselves in Andorra. We have incorporated over 400 companies, assisted over 400 families with residency and managed the tax affairs of over 300 active clients from 30+ nationalities.

MCA Assessors today serves clients from across Europe, Latin America and Asia, with the same standards of quality and confidentiality that have defined us since 2013.
