Why Challenging Children and Montessori?


More and more schools are experiencing an increase in enrollment of students with special needs. 

The Montessori Method is wonderfully suited for children with exceptionalities, but many Montessori guides struggle to understand and meet the needs of challenging children while peacefully including these children in a normalized classroom. 



Brynn and Maria Eva have partnered together to create Challenging Children and Montessori to help future generations flourish. Their mission is to support the Montessori community by providing professional development and consultative services to educators and organizations in order to best meet the needs of every student; challenges and all.
