It's a made up word. A cross between "Art" and "Atelier". Atelier means workshop in French.
It should be pronounced ar-tell-ee-ay.
Artelier is an art studio on wheels based in village of Port Jefferson, New York. We are focused on art making, thinking, exploring, discovering, and imagining. We hope to provide experiences where families and the community can explore art making and share in the creative process. We offer a range of creative experiences including age-specific classes, workshops, birthday parties for all ages.
Wherever we are, we hope to provide an environment that nurtures creative thinking and where children feel comfortable to express their ideas and create in a non-judgment zone. Always focusing in the creative process and experience rather than product, encouraging collaboration, communication and exploration.
