Theater is where everything started and where Andressa dedicates most of her creative energy. She has always been drawn to creating original works and since she attended the Mitu Thailand Artist Intensive in Bangkok she has been focusing in creating original work that often involved physical theater and multimedia such as her solo work free•dom - a solo of many people, awarded Best Multimedia Show at the 2012 United Solo Festival in New York. In 2011 she co-founded Group .BR, NY's only Brazilian theater company where she serves as artistic director. In 2014, .BR's Infinite While it Lasts was nominated to the Innovative Theater Awards for Best Choreography. All Group .BR's productions, The Serpente, Infinite While it Lasts and Inside the Wild Heart, and free•dom - a solo of many people were nominated to the Brazilian International Press Awards and in 2017, after five years in a row being nominated, Andressa received the award for her acting in Inside the Wild Heart.
Performance art and installation ideas have always roamed Andressa Furletti's mind but it was only after being a participant at the Watermill Summer Program that she started to understand those ideas and how to bring them to life. Since 2011 Andressa has been creating and presenting durational performances and art installations.
Visual arts has influenced as lot of Andressa's artistic creations and has been a recent outlet for some of her ideas and to some collaborations such as with the multidisciplinary artist Montserrat Vargas and the photographer Rizza Bomfim.
