CEO - Founder

Guilherme Cesar Immigration Lawyer, originally from Brazil, immigrated to Spain in 2017 as a student—a path that is widely used today, but which at that time involved numerous additional challenges.

Thanks to the excellence we uphold in our firm today, and after years of academic dedication, he earned a Double International Law Degree, having graduated from the University of Alicante, one of Spain’s most prestigious institutions for legal education. He also obtained his Law Degree from the University of Vale do Itajaí – UNIVALI, ranked among the top private universities in Brazil.

In his pursuit of a solid legal career, he successfully completed the Master’s Degree in Access to the Legal Profession at the University of Alicante, and in 2022, became a registered member of the Alicante Bar Association – ICALI.

Always striving to better serve our clients’ needs, in 2024 we expanded our activity to the province of Valencia. That same year, Guilherme Cesar completed the Master’s Degree in Maritime Law and Economic-Port Management offered by the Catholic University of Valencia – UCV.

Currently, in addition to practicing law and leading the firm’s operations, he is also involved in academic research as a PhD candidate in Law at the University of Alicante – UA.
