evidence-based instruction for struggling readers and spellers

Our Focus


The Orton-Gillingham approach is an intensive, sequential, evidence-based system that teaches the basics of word formation before whole meanings. The approach accommodates and utilizes the three neurological pathways through which people learn, and it teaches to a student’s strengths while improving their weaknesses through explicit and systematic phonics instruction.


Cardinal Reading provides highly interactive, multisensory language training sessions online using premium web-conferencing software or at our location during a time that fits your schedule. If you are unable to come to us, we will provide the same quality instruction in your home or designated school (additional travel charges apply).

Reading Assessments

We offer a reading assessment battery consisting of five testing protocols: The Gray Oral Reading Tests-Fifth Edition, The Gray Silent Reading Tests, The Comprehensive Test of Phonological Processing-Second Edition, The Test of Word Reading Efficiency-Second Edition, and The Assessment of Sound/Symbol Correspondence.

Educational Advocacy

Obtaining educational services for your child can be an overwhelming proposition, especially considering the emotional attachment to the outcome. We offer effective and supportive consultation to parents as they navigate through the educational minefield. If need be, we will speak on your behalf.
