Cogo began her career as a humanities teacher in a local middle school[1] and later taught literature.

[2] In 1985 she was elected to serve on the City Council of Tione,[2] as a candidate from the Italian Socialist Party.

Her term was faced with ethnic conflicts and she worked for their resolution,[1] through initiatives to ensure the autonomy of the region and reform the electoral codes.

In that capacity, she worked to create the Museo della scienza (Museum of Science) (MUSE) and spearheaded a major multi-year project, focused on researching and recovering cultural heritage centered on the Great War.

The project aimed at restoration of monuments and buildings in the region, such as Fort Cadine, the Loggia del Romanino at Buonconsiglio Castle, the Malga Palazzo Nature Reserve at Scanuppia, the Ruatti Mill at Rabbi, the Torre Vanga in Trent and the Venetian Bastion Monument in the Bondo cemetery in Riva del Garda, as well as establishing museums throughout the area.
