My daughter has struggled with her Algebra 1 class all semester. She had the opportunity to retake a test she had previously failed. I knew that she needed a tutor if she was going to have a fighting chance and I found Mr. Kevin with wonderful reviews. He definitely deserves all of them. I could tell from her first session that it made a world of difference. He even gave her some practice worksheets. Thank you Mr. Kevin!

Professor Kreighbaum is probably the best tutor I’ve ever had. He is very patient and knowledgeable and will meet you at your level and explain things as thoroughly as possible. I went from having to drop a class because I couldn’t grasp any of the concepts to acing all math courses I’ve taken since then, including the one I had to drop. He helped build my confidence and never once made me feel lesser than for not understanding something or taking a little longer than usual to grasp the concept. All in all, a great teacher!

We contacted Kevin to tutor our high school junior with their Differential Equations class as their school takes a blistering pace. We were impressed Kevin’s knowledge and teaching ability. He is a great math resource.

During my time with Mr. Kevin, he was a huge help in my Precalculus Honors class. He explained advanced topics clearly, and we even went ahead of the curriculum often times. Mr. K actually made sure I understood the steps of each problem, which was especially important during the first semester of precalculus when dealing with Trig and applications. Overall, he was very professional, responsive, and reliable whenever I needed help. Thanks to Mr. Kevin, I became much more confident not only in the classroom, but also in myself and in everyday life! I am truly grateful for all the support.
