The Story of Yo Re Mi…

Rachel Costello and Dan Costello created Yo Re Mi while teaching after-school classes in NYC. Dan was a music teacher incorporating a lot of dance and physical movement. Meanwhile, Rachel was singing through her entire kids yoga class.

One day, they combined their classes, wrote some originals songs for their yoga sequences and Yo Re Mi was born. Children were instantly engaged by the new material and loved sharing their own ideas for adventures that would take them to outer space, the jungle, other countries or their own back-yard.

Dan and Rachel continued writing and developing, and now there are hundreds of Yo Re Mi songs, videos, and lesson plans which are customized to the needs of individual classrooms.

Yo Re Mi offers school-day and after-school programs for children around NYC, online videos and songs for children and families everywhere, professional development workshops for teachers, and a children’s yoga teacher training.
