Marillac's Therapeutic Day School offers a highly structured, individualized therapeutic education program for students first through eighth grade in a small class setting. Staff are highly qualified and licensed in their areas of expertise. Marillac's school coordinates services with school districts, families and community mental health providers to promote a successful reintegration to the public school setting.

Marillac offers Therapeutic Day School programs in two locations: Overland Park, Kansas and Blue Springs, Missouri. Both schools provide special education services for difficult-to-place children who have demonstrated problems in adjusting and maintaining stability in their individual school settings. The school in Overland Park also provides an Assessment and Planning phase appropriate for children who may be entering the special educational environment and present with questions of placement and/or diagnosis.
