Years of history


We look to the future to continue for another 35 years as one of the country's leading professional services firms.

Adlanter was conceived as a service option in the late 1980s. Initially, it was under the supervision of the auditing firm Audihispana, now Grant Thornton, but soon after it began operating as an independent firm with its own strategy, offices, and service offerings. The initial goal was to complement the services provided by our parent company to its clients, by providing them with a management and administration services company. This initial approach expanded over time, in response to the market and clients, to become what Adlanter is today: a multi-service company in the legal market with national coverage, presence and experience in multiple sectors, and its own identity.
