Yoshimoto Orton-Gillingham Approach (YOG-A) 40 hour Training 
This five-day O.G. training will focus on a data-driven, clinical, multisensory, phonetic, teacher guided Yoshimoto Orton Gillingham approach to teaching reading, writing and spelling in the whole classroom, small group, and one-to-one settings. Upon completing this course participants will have acquired the skills necessary to fully implement this data-driven solution for teaching reading to all students.  Teachers implementing the Yoshimoto method with fidelity are demonstrating consistent and significant growth that is being replicated across the U.S. Perhaps more significant is that teachers love the course, the materials and the success they are seeing in their classrooms and interventions.
The course will cover the three levels of decoding and spelling: sound, syllable, and an introduction to the concept of morphology. With the latter, introductory morphology, the emphasis will be on increasing the vocabulary for all children - general and special education students.  Further, the system supports the outcomes within the Common Core.We also discuss Dyslexia, the brain and early and ongoing identification of these students.

All materials needed for implementation of the full program are included in the cost of the course. Further, there will be extensive additional materials provided including: multiple CDs with about 6,000 worksheets dealing with syllabication, sounds, rules and generalizations.

For whom is the O.G. approach appropriate?
The O.G. approach is appropriate for classrooms, small groups and teaching individuals; primary, elementary, intermediate, secondary, college, and adults. This class is designed specifically for kindergarten, primary, elementary & middle school classroom teachers, tutors, reading specialists, special ed teachers and home-school parents.

O.G. teaching sessions are action oriented with auditory, visual, and kinesthetic elements reinforcing each other; spelling is simultaneously taught with reading.

Structured, Sequential, Cumulative
Teaching proceeds from phonemic awareness, phonics, syllable types, syllable division rules, spelling, vocabulary, sentence structure, composition, and reading comprehension.

Data Driven, Flexible, Cognitive
O.G. is data-driven, diagnostic-prescriptive teaching at it's best. The teacher designs and implements lessons based on the data gathered from the individual student and/or the classroom group.  The instruction is targeted at the needs of the students and paced to insure the level of mastery that supports ongoing success for all students.  Further, the method includes targeted interventions for students who require more repetitions or intensity. The teacher always seeks to understand how an individual learns and devises appropriate teaching strategies using students' strengths while accommodating their weaknesses.


Sean graduated from the University of Northern Colorado in 2007 with B.A. in History and an emphasis in Secondary Education. Soon there after he found his true calling and got a second license in Special Education. He taught both center-based and mild/moderate needs special education classes from 2008-2021. In 2021, he moved to the district level and became a Special Education Coordinator. 

Sean was lucky enough to attend a Yoshimoto Orton Gillingham training in the summer of 2017. He immediately realized this was what he’d been looking for to reach his struggling readers. During the course of the following school year, Sean completed the process of becoming an Orton Gillingham Certified Teacher. He eventually became an OGI Master Trainer in 2019. 

Sean continues to take every opportunity to learn more about how to best educate our students who struggle with literacy. He also works to develop professional development around literacy and to bring Orton Gillingham to his current school district.
