Sounds In Syllables

SIS, a therapeutic level dyslexia remediation program developed by Sandra Dillon in the 1980's, is exceptionally effective for individuals with dyslexia, spanning from mild to profound levels. Our SIS materials are exclusively accessible to dedicated Academic Language Therapists who have completed comprehensive training courses in SIS through the Atlantic Seaboard Dyslexia Education Center (ASDEC) or the Multisensory Language Training Institute of New Mexico (MLTI-NM).
