Sabina Oberholzer studied with Livio Bernasconi, Sergio Libiszewsky and Bruno Monguzzi at the CSIA
in Lugano. 
In 1983 Sabina founded the Studio di Progettazione Grafica with her partner Renato Tagli in Cevio, 
in the Italian-speaking region of Switzerland. 
Oberholzer and Tagli are alive to the relationship between nature and creativity, 
and sensitive to their responsibilities within the small community in which they live and work. 
Driven not by economics but rather by a belief in quality and clarity of the message, 
Oberholzer’s design philosophy is based on appropriateness and generally results in the elimination 
of the superfluous, ornate or artificial.
In 1985, they won the contest for the creation of the corporate identity of the city of Locarno. 
In 1987, they were responsible for the design of the newspaper Quotidiano, 
for which the following year they won a prize from the Federal Scholarship for Applied Arts, 
a feat they repeated two years later. 
They were second in the contest for the best Swiss corporate identity in 1992.
In 1995 they created the new corporate design for Monte Verità.
In 1998 they began work on the corporate design for the Museo Comunale d’Arte Moderna Ascona.
