What people are saying.

  • “I am thrilled to recommend Harriet as a math tutor. Harriet has been a dear family friend for years, and her impact on my academic journey, especially during high school, has been invaluable. Not only is she incredibly skilled at what she does, but she’s also one of the most caring and supportive people I know. Harriet's tutoring sessions helped me immensely—not only did my understanding of math improve, but I also gained confidence in tackling challenging problems. She has an incredible ability to make even the most difficult topics feel manageable. Her patient, encouraging approach made all the difference for me, as she would go over things as many times as I needed without ever losing patience or belief in me. Harriet truly cares about her students’ success, going above and beyond to ensure they feel supported and capable. For anyone seeking a highly skilled, compassionate, and dedicated math tutor, I wholeheartedly recommend Harriet. She is a gifted educator and an incredibly kind-hearted person who has a genuine passion for helping her students succeed."

  • “Harriet Kaizer has been an outstanding tutor for our 15-year-old son, who took Algebra II as a sophomore. While he enjoys math, some aspects of Algebra II were challenging, and he needed extra support to raise his high B to an A. We initially tried a group-based after-school program, but the format wasn’t effective for him. Harriet’s one-on-one approach, however, made all the difference! Her enthusiasm is contagious (she even said, “Algebra II? That’s my jam!”), and her ability to break down complex concepts made everything easier to grasp, giving him a real confidence boost before tests. Thanks to Harriet, our son achieved and maintained an A in Algebra II, and he scored a 710 on the SAT math section on his first attempt! Her passion and dedication gave him the skills and confidence to excel. We couldn’t be happier with the results and highly recommend Harriet to anyone looking for an exceptional math tutor!“

  • “As a student, Harriet has been instrumental in strengthening my math skills over the past few years. Her approach to teaching is so clear and effective. She has a real knack for breaking down complex concepts in a way that builds true understanding, especially when my classroom instruction wasn’t enough. Harriet was incredibly generous with her time, always making herself available whenever I needed extra support and ensuring I felt comfortable asking questions. Her dedication and patience made a real difference in my confidence and performance in math. I highly recommend her to any student looking to excel.”

  • "Harriet Kaizer, was instrumental in helping both of my children navigate the challenges of high school math. Harriet understood their unique challenges and was able to help them access the content of their coursework successfully. Having worked with thousands of students over the decades, she has honed her craft. However, it is not just her expertise that sets her apart, it is her genuine care, warmth, and ability to build meaningful relationships with each student. I wholeheartedly recommend Harriet.”

  • "Harriet Kaizer made a huge difference for my daughter in high school! She took pre-calc and Harriet was her tutor on and off during the semester, and the results were amazing. Harriet has this incredible way of making tough concepts click, and thanks to her, my daughter not only did well in pre-calc, but she also placed out of calculus in college! Harriet’s passion and knack for teaching really helped my daughter build confidence and skills that set her up for success. I couldn’t recommend her enough!"

Her ability to simplify the problems and explain how one gets to a solution, empowered my daughter, giving her the confidence needed to ace all her tests. She actually enjoys math now because of Harriet.”
