Teatro Stabile di Grosseto was founded in October 2000 as professional theatre company. Now Teatro Stabile di Grosseto addresses its main attention to the world of childhood and adolescence through the production of theatrical performances focused on educational issues of great impact:  acceptance of diversity, integration, correct use of media and Internet.

In 2003, after only 2 years and 3 months of activities, Teatro Stabile di Grosseto received the award of  "Teatro Stabile" (the most important Italian award in the field of theatre) from the Ministry of Cultural Heritage. The following year Teatro Stabile di Grosseto received the "Body of National importance" award from the Tuscany Region.

In 2004 and 2005 Teatro Stabile di Grosseto won the most prestigious Italian theatrical award, the "Golden Ticket", the only award attributed to those theatrical companies which collect the highest number of spectators throughout the National territory during the theatrical season. Based on these important results, TSG proceeded to the transformation from theatre company to cultural entity and extended its activities to Film and Music.
