Hear Our Success Stories!

"We had been searching for answers to our child’s learning difficulties. We had him tested for special education and a variety of related services. All of his test scores were average to above average. He continued to struggle with reading. Excel was the answer to our prayers. We finally had the reason he was struggling, but most importantly, Excel knew how to help him. He went from below grade level to at or above grade level after his program. The biggest benefit was the confidence he gained through the program. The teachers are highly qualified and do an amazing job. We loved the postcards sent to our son. They made him feel so good. We highly recommend Excel and will enroll our child again if we need to. Thank you for giving our child the tools to be successful and the confidence that he now has. Our prayers were answered!"

Jen C

“My son’s summers at Excel have been well spent. Through his tutoring at Excel, he has skipped 2 grade levels of math! Ensuring that he had mastered the material he skipped and then front-loading the new material to ensure success has been instrumental in helping him reach his full potential.” “Excel was a great program for Natalie. She always looked forward to going to tutoring and was excited to tell us what she learned. She was very prepared for school to start. Natalie is having a great start to 6th grade thanks to Excel.”

Kathy Ragels

"Our college-aged daughter recently took the study skills class at Excel and it was terrific. They were able to keep her interested and excited to learn for the entire summer when she could have been doing other “fun” things. She was able to connect the things they suggested to how she works best and now is looking forward to applying these new found techniques to her college classes this year. Thanks for working her into your busy schedule and showing her how to handle her disability and giving her the tools she needed to be even more successful. Best money we’ve ever spent on our daughter’s education bar none!"


Our son entered the fourth grade reading at a second grade level. After 90 sessions of Excel Achievement, he is reading above his grade level. Before Excel Achievement, he had a hard time writing, spelling and reading. All of these problems have improved for him. I thought it would be a fight to get him to go but he was always willing and always happy after his sessions. Excel Achievement made learning fun! As a parent, the staff was very supportive and assisted with our struggles with school meetings about our son. I really appreciated that! Over all, we are extremely pleased and would (and have) recommend Excel Achievement to others!

Carrie Sanchez

"Our 5th grade daughter was testing at a 3rd grade level. After one year in the writing/spelling program at Excel, she is now testing at current grade level. Grades went from C’s to A’s in most areas and we can see more confidence in everything she does."


Going to Excel Achievement has not only improved both of my children’s knowledge of specific subject areas, but also made them more active learners. With the confidence they gained through tutoring, they are the first ones to raise a hand, form a hypothesis, or tackle a challenging assignment. This confidence flows from their academic endeavors into all aspects of their lives.
