Our faculty is comprised of an exceptionally devoted group of professionals who are well-qualified and experienced. Each staff member is a model of the excitement of lifelong learning, and each year teachers dedicate many hours to continuing education in order to stay abreast of research-based best practice to bring to their teaching repertoire. 


The commitment of MJDS teachers to each child and family does not stop at the classroom door; teachers maintain ongoing communication with parents and welcome family participation.

She’s served as director of student support for Le Monde Immersion School, a Portland Public School charter program, and as special education facilitator in the Beaverton School District.
