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.

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 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 is very patient, provides clear explanations of concepts and always made sure my 8th grader understood before moving on to the next topic. Sessions were flexible based on current needs and were always engaging.

Mr. Laiche was instrumental in catching our daughter up in Algebra after an extended illness that caused her to miss over a month of classes. He is well worth the investment!

We really appreciated Drew’s support through precalc. My son found him to be very supportive. I think he was able to expand my son's thinking around math. He is a professional math tutor and the online tutoring was very convenient. We will definitely work with him again in the future as needed.

Drew has a great rapport with our 13-year old son who is geeking out on math. He looks forward to his tutor sessions with Drew and seems to absorb everything he is learning. We have even recommended Drew to a couple other families who are equally pleased with their kids’ improvement in math.
