    Our 7th grader has been lucky to have Drew as our math tutor for the past year. Aside from the obvious and measurable improvement in grades, we have also noted an increase in confidence and overall interest in math. He now looks forward to his tutoring sessions and has enjoyed the ability to ask questions at his own pace and learning style.

    Drew tutors both of my daughters who are at different math levels (Junior, Pre-Calc and 8th grade, Compacted math). He flawlessly transitions from one to the other. Both of my daughters have said he has been a huge help and they really enjoy working with him. We appreciate that he can come to the house and scheduling has been easy. My girls would highly recommend him!

    In the middle of 7th grade, our son fell behind in math, and was embarrassed to ask for help. We tried to mentor him, but found it extremely frustrating to productively teach him ourselves. I immediately searched for a math tutor and found Drew, he has mentored my son now for over two years. We are beyond grateful for his expertise. He not only is an excellent teacher, he makes math fun. My son looks forward to the math sessions with Drew. Drew is very familiar with the PPS math curriculum. Above and beyond math, he is reliable, organized, professional, kind, and builds his student's confidence. My son's math grades are A's. I can't say enough good things about our experience with him. Thank you Drew!

    The kind of math tutor I wish I had when I was in school. Drew is excellent in every way. Deliberate, clear, and calming. He provides a wealth of supplemental material and teaches in a refreshingly clear and concise way.

    Drew’s materials and ways of explaining and showing processes have been really helpful and relevant to what I’ve been working on in class and he’s helped me understand the material a lot better.

    Drew has been an amazing support for my daughter. For the past few years he has helped her understand more of algebra and geometry with one-on-one sessions, personalized homework, access to focused online learning, and feedback. It has made such a difference. Thank you, Drew!

    Drew has been fantastic. He is patient and engaging. Our son is starting high school next year, and thanks to Drew, he feels more confident about skipping algebra and taking an advanced math class. His understanding and skills have noticeably improved in a short time. Definitely recommend!

    I had Drew as a tutor for about 8 months and he helped me so much at understanding my math better. He really helped me break down each question and help me better understand it. Would definitely recommend!
