“My grandson is now in his fifth year of sessions with Joe and Sentryl. When they began, he was over a year behind in math for his grade level, and now is taking college math and science courses in high school.”
“My son worked with Joe to address his testing anxiety and prepare for college admissions. His ACT score increased from 19 to 25.”
“Joe was a huge help to my daughter when she needed some tutoring. He was patient and supportive while holding her accountable as well. He was also very flexibile with scheduling. He was always willing to meet prior to a quiz or test and gave her extra time when needed. I highly recommend Joe without reservation.”

“Stephen used real life examples in teaching my daughter fractions. She was able to cut up different types of fruit to understand denominators and numerators in fractions. The one on one intervention has been so important to learning as well as her self confidence.”
“Joe has tutored my child through several honors math courses as well as a college math course. He is brilliant and has an unbelievable ability to get students to understand very complex and difficult coursework. It always amazes me how my child will go into a session with him lost and confused, then come out fluent on the subject, getting an A on a test the next day. Joe has also been very flexible, adapting to our schedules even last minute.”

Learning Disability Services
“Joe helped my son with his dyslexia. The amount his reading has improved is amazing, thanks so much!”
“My daughter worked with Stephen for 6 months. When she began working with Stephen she was in the 2nd semester of 6th grade and was reading on a 2nd/3rd grade level. He worked with her on the phonetics of the English language by breaking down the sounds each letter makes. Once she had an understanding of the sounds she was then able to use that knowledge in order to read the words. In the 6 months that he worked with her, she improved to. 7th grade fiction reading level. I highly recommend his services. The one on one intervention has been so important to learning as well as her self confidence with reading.”
“We were blessed with the opportunity to work with Stephen after the school determined a significant gap between my son’s fluency and his ability to recall and comprehend what he reads. His imagery skills were basically nonexistent and we struggled with basic grammar as well. Most of our homework includes art, games and things that my child is interested in.”
“Despite over half or more of our sessions being via Zoom due to Covid, Stephen was able to captivate and maintain my son’s attention and we made significant progress despite the less than ideal conditions.”
“I highly recommend Stephen if your child is struggling in the areas of reading, and speech, has a language disorder, not making progress in the areas of language, speech, reading, and comprehension in regards to their IEP goals, or needing someone to make recommendations to your IEP team or teachers on presentation of materials.”
“Stephen is an absolute dream to work with!”
“His patience and his faith in my son are what set Stephen apart.”
“Stephen identified quickly that my son is a natural environment learner and tailored everything to fit his learning style. I loved how he gave us things to work on at home that were practical and didn’t feel like actual work.”
“Stephen worked with my son at his school and even through distant learning during the Covid pandemic.”
“My son is on the more severe end of the Autism spectrum with a severe receptive and expressive language disorder. It is very difficult to find someone who not only has the skill set to work with him but the desire. Throughout their time together they worked on imagery, comprehension, prepositions, verb tenses, adjectives, fluency, comparing and contrasting skills, and inferencing.”
