About us

History

ANDERSEN BALLÃO ADVOCACIA was founded in 1979, in the city of Curitiba, by lawyer Wilson José Andersen Ballão, shortly after graduating in Law from the Federal University of Paraná. The firm was created with the objective of providing high quality legal services, initially in the area of ​​International and Maritime Law, with individual and corporate clients, both national and foreign. In the mid-90s, the firm expanded its range of activities to meet the great demand arising from the high level of its services. Specialized departments were established for the main areas of law. Since then, the firm has consolidated itself as one of the most admired stalls in Paraná. Currently headquartered at Avenida Jaime Reis, in Curitiba, the firm maintains a team of specialized lawyers who are fluent in several languages. In addition to the experience of our professionals, the office has an efficient team of assistants and an excellent infrastructure, within the most demanding international standards.

This property, which now houses several departments of Andersen Ballão Advocacia, dates back to 1976. The original project was elaborated by the renowned and late architect Julio Pechmann. Initially designed for a vocational school, it was also a famous nightclub, gym and dance school.

In 2015, architects Mariana Manzoni and Rafael Gonçalves, maintaining the pre-existing construction project, transformed the more than 1000m² into modern facilities for up to 95 jobs.

German Recognition: Cross of the Order of Merit

German Recognition: Cross of the Order of Merit

It was with great joy that Wilson José Andersen Ballão, founding partner of ABA, received in his office the visit of the Deputy Consul General of Germany in São Paulo, Uwe Heye, at the end of April 2015. The Consul came to inform that the Federal Republic of Germany had chosen the lawyer to receive the Order of Merit Cross. It is an honor granted to German or foreign citizens who have contributed to the development of the German Republic in the socio-economic or intellectual fields. The award was officially presented at an event held in May of that year.

It is the first time that the Cross of the Order of Merit of the Federal Republic of Germany has been awarded to a Curitiba native, which left the ABA founder very honored. Dr. Ballão was a fellow of the German government, is a founding member of the German-Brazilian Society of Lawyers (based in Frankfurt), was Director of the Brazil-Germany Chamber of Commerce for nine years and, today, he serves as an adviser to the entity. Through his law firm, he has also been working to strengthen business relations between Brazil and Germany for over 35 years. “Everything I did was also in gratitude for what I already received from the German Government,” said Wilson José.

The current director of the Chamber and Honorary Consul of Germany in Curitiba, Andreas F. H. Hoffrichter, confirms that the lawyer's role in strengthening relations between the two countries has been significant. “Dr. Ballão contributed with the arrival of several companies of German origin to Curitiba, in addition to constantly working to strengthen business between the two countries”, declares the Director.
The official delivery of the honor took place at a ceremony held at the Concórdia Headquarters of Clube Curitibano and was attended by the Deputy Consul General of Germany in São Paulo, Uwe Heye, and authorities and personalities of the State of Paraná.
