Susan Williams bio pic.jpg

Reading Specialist, Certified Special Education Teacher, Certified History and English Teacher

Susan Williams

Susan has been involved in education for 23 years. Her first years in education were spent in summer reading programs for disadvantaged children and teaching all subjects (K-8) in private education. She earned a B.A. at U of M with teaching certifications in English and history. For ten years, she worked as a middle school Language Arts teacher at a private school in Detroit. Susan was known for her rigorous writing and reading instruction that helped many students gain entrance into the very best public and private high schools in the Metro Detroit area.

Following a year of research and writing, she finished her thesis: How ADHD Effects Reading Fluency and Comprehension. Having spent years of study and writing her thesis, Susan was granted a M.A. by Madonna University in Special Education, focused in learning disabilities. She later resigned her position as a Language Arts teacher in order to work as a K-12 Resource Room teacher.

Susan began to tutor professionally as a result of meeting a student who struggled in his kindergarten class with phonics, numbers and was recommended to repeat another year of kindergarten. After completing a summer of tutoring with Susan three to four times a week for two hours per session, the student was able to continue to first grade. Susan realized from that experience that rigorous, one on one tutoring can often provide students how to make sense of numbers and to establish reading foundations they may have missed in an entire academic year.

One of Susan’s greatest pleasures is to witness a student’s face and newly found energy when they discover they can read, calculate and write: from there they take off on a marvelous journey in education.  Another of her joys is to see a renewal of a student’s self-esteem as they discover those feelings of achieving academic success!
