The Tappan Zee Dance Group (TZDG) was formed in 1987 with the original purpose of providing working space and administrative support for a co-operative group of professional dancer/choreographer/instructors. For 19 years, the TZDG (incorporated in 1989 as a non-profit arts organization; and an affiliate organization of the Westchester Arts Council) has defined its mission: to serve the art form of dance by supporting its practitioners; by providing cultural enrichment to our community through dance; and by training professional dancers. The TZDG teaching faculty consists of instructors chosen for the strength of their professional background, credentials in performance and choreography and dance pedagogy. Students from Westchester County and the surrounding areas aged three through adult are enrolled yearly in a range of classes that include pre-ballet/creative movement, ballet, jazz dance, modern dance and rhythm tap.

All students at TZDG have many opportunities to perform, including the Spring Student Dance Performance, the Open Houses held at the studio and various appearances at local dance events and festivals. The Repertory Company is TZDG's teen performing group that is geared towards the professionally oriented dancer.
