The Greenhouse Theater Center hosts multiple Off-Loop theater companies, including Eclipse Theatre Company, Hubris Productions, MPAACT, Organic Theatre Company, Remy Bumppo Theatre Company, The Magic Cabaret, and Theater Seven Of Chicago.

This multi-stage artists' space provides five stages, dressing and staging areas, as well as, office space for resident companies to grow.

The Greenhouse Theater Center is home to Lil' Buds Theatre Company as well as Marsha's Music.

Both organizations provide various arts education to children through classes and summer camps.

This international endeavour will kick off with Chicago playing host to the Norwegian students enrolled in this new program and taking classes in the four Greenhouse Theater Center spaces with performances at both Greenhouse and Gorilla Tango Theatre.
