    Drew has been great working with both of our sons for the last year & has been wonderful, patient & creative, especially with navigating distance tutoring. He is adaptable to school curriculum as well as other learning platforms. He understands the social-emotional aspects of math anxiety, and has been enormously helpful to us parents with adjusting to online learning. Very grateful to be working with Drew!

    My daughter is taking Advanced Algebra 3-4 Honors. She was struggling and her grade dropped to a D. Mr. Laiche provided her exceptional guidance and just had her final and received a final grade of B. We believe continued Tutoring should elevate her grade further. We highly recommend Mr. Laiche for math tutoring.

    Thank you Drew! We have had a wonderful experience with Drew as two of my daughters' (7th and 12th grade) math tutor for a year now. He is always professional, on time, provides content and knows how to motivate my girls to do better.
    He was able to pivot to an online platform almost instantly when the pandemic stopped our ability to meet in person and we appreciate his efforts and success with that change.
    My girls have seen amazing results from their weekly meetings with Drew and they have continued to increase their individual abilities in math and in the language of math. I have full faith in Drew's ability to aid my children in becoming more confident and successful in the subject of math at any level while learning to enjoy the subject as well.

    Drew worked with my 13 year old daughter throughout the summer. This greatly improved her confidence and her aptitude. She had been taking algebra in 8th grade, during her sessions they dove into concepts she was struggling with working ahead to geometry. Definitely a very logical approach to tutoring, and my daughter listened to Drew, much more than me! I feel like he showed a great deal of patience, overall was a positive experience and worth the price.

    Our son has thrived in his advanced Algebra analysis class in high school because of Drew. He went from a C to straight A's the whole year. The online platform is fantastic and easy to navigate. Drew is easy to communicate with. We highly recommend him and are very grateful for his help!

    Drew has been a great tutor for our high school sophomore. He explains concepts and provides feedback. Our son has a better understanding of concepts and his homework. Drew has been great about scheduling and he is very organized. We are very happy with Drew!

    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!

    Mr. Laiche is a great tutor and has done such an excellent job helping our daughter through her Geometry class. With his help, she has received an A grade for the semester. She truly appreciates the thorough way in which he explains new concepts and how he breaks them down to simplify them. In addition to that, he is very responsive, punctual, and makes online learning easy. If you’re in need of a tutor, Mr. Laiche is a fantastic choice!

    Drew is fantastic! We worked with him for the first time thru all of distance learning and will continue with him once the girls are back in school as well. He’s very patient and communicative. Our oldest daughter chose to switch to compact math because she “felt more confident” since starting math tutoring with Drew, and our youngest “doesn’t hate math anymore” :) We highly recommend Drew - in fact our 2 closest family friends use him too.
