Our History


Sister Anthonita Porta, OP, a Dominican Sister who spent 18 years in education before becoming a Montessorian in 1969, establishes the Montessori Children’s House at St. Joseph Academy in Adrian, Michigan with Sister Leonor J. Esnard.

The Adrian Dominican Montessori Teacher Education Institute (ADMTEI) is founded by Sister Anthonita as a nonprofit and begins its credential program for Montessori teachers. It is accredited through the Montessori Accreditation Council for Teacher Education (MACTE).

Sister Anthonita steps down as administrator of the Montessori Children’s House in order to concentrate on teacher education and to assist in setting up Montessori schools throughout the country and the world. Sister Anthonita works tirelessly as an advocate for children, the poor and the disadvantaged.

Sister Anthonita is named a Living Legacy by the American Montessori Society.

Sister Anthonita passes away unexpectedly and Sister Leonor Esnard assumes the Directorship of ADMTEI.

The spirit and legacy of Sister Anthonita continue as ADMTEI celebrates 20 years of high-quality Montessori teacher education!

ADMTEI renews its accreditation through MACTE and remains accredited through 2021.
