The story of our legacy

Our firm is led by the fourth generation of Gassiot’s. It all started in 1903 when Josep Gassiot Magret earned his place in the Colegio de Abogados [Bar Association] in Barcelona. He chose the beautiful Passeig de Gracia for the original office location, right next to Casa Batlló.

In 1928, his son Joan Gassiot Llorens joined the Colegio de Abogados and soon opened a second office on nearby street Mallorca. Once Joan’s son, Joan Gassiot Calvet, also joined the Colegio de Abogados, he started with his grandfather Josep Gassiot in 1959. The following year the three sons and fathers moved together.

Since then, the firm has been open at this Mallorca 303 location. This is where Joan Gassiot Benet began in 1987, following his great-grandfather’s footsteps.

Today he continues this legacy by leading the office to care for and defend all of their clients. We pride ourselves in continuing the trust of our clients to their succeeding generations, as well. We have worked with them as if they were our own family.

But the impressive line of Gassiot’s lawyers isn’t finished, the fifth generation Gassiot is expecting to carry on in the coming years.
