Brochure and Application Form

The Multisensory Language Training Institute of New Mexico (MLTI-NM), founded by Director Emerita Sandra Dillon, trains teachers and other education professionals in Sounds In Syllables Multisensory, Structured, Language Therapy (SIS). Sounds In Syllables was developed as a language re-training therapy for students of all ages whose reading and spelling is severely impaired by developmental dyslexia. Certified graduates of MLTI-NM possess the knowledge and skills necessary to teach individuals with dyslexia – and other language-based learning difficulties – to read, write, and spell. 


MLTI-NM’s main focus is to train at the therapy level. Its Dyslexia Therapist training course is accredited by the International Multisensory Structured Language Education Council (  IMSLEC began as a committee of the Orton Dyslexia Society (now The International Dyslexia Association) in 1990, and became an independent institution in 1995, accrediting MLTI-NM in 2001. MLTI-NM received its most recent reaccreditation in July 2022, accrediting our institute at the Therapy and Instructor of Therapy Levels.

The International Dyslexia Association recognizes IMSLEC an an Independent Accreditation agency. “Programs awarded AccreditationPlus have received IDA accreditation and also produce educators who have engaged in intensive supervised practicum experiences that were sufficiently designed and staffed to promote applied mastery of the principles and practices of structured literacy in the service of preventing reading failure and remediating off-track readers with profiles characteristic of dyslexia.” (Source: Click here)


Sandra Dillon founded MLTI-NM in 1987 after years of working with bright, dyslexic students in the Albuquerque Public Schools. While she continues to be an MLTI-NM instructor, this Institute is now owned and directed by Mary Poirier Gilroy, who began training with Sandra Dillon in 1989 and who practiced as a Certified Academic Language Therapist for over 20 years in the Taos Municipal Schools. 

Ms. Dillon continues to own and operate S.I.S. Publishing Co., the source of all materials used in MLTI-NM training. 


MLTI-NM is a training institute “without walls” but with an office in Taos County, New Mexico. While training can be arranged at sites throughout the Southwest region and beyond, most classes are offered on a regular basis either in Albuquerque or Taos or via Zoom.  (See Contact Us for more information)

People often ask me, “When are you going to retire?” I always respond, “Why would I leave work that brings me and those whose lives I affect so much joy?” I have Sandra Dillon to thank for my life’s passion,…and for setting the standard of excellence so high.” Ann R., Class of 1994
