Bio

Hey there! My name is Zachary, and I’ve spent the last 10+ years teaching and tutoring mathematics at the high school, college, and international levels. With a B.S. and M.S. in Engineering and a Certificate in Machine Learning, I bring a unique combination of academic expertise and real-world problem-solving skills to every session.

Hey there! My name is Zachary, and I’ve spent the last 10+ years teaching and tutoring mathematics at the high school, college, and international levels. With a B.S. and M.S. in Engineering and a Certificate in Machine Learning, I bring a unique combination of academic expertise and real-world problem-solving skills to every session.

Calculus is my specialty. Whether it’s AP Calculus AB or AP Calculus BC, college-level Calculus 1 and Calculus 2, or preparing for CLEP exams, I help students understand the toughest topics with a step-by-step approach that simplifies the process and delivers results. My students consistently achieve 4s and 5s on AP exams, ace tests, boost their GPAs, and leave sessions with the confidence to handle anything calculus throws at them.

In addition to our time together, I offer a handful of resources accessible outside of our lesson to help you help yourself. This includes Youtube videos, downloadable formula sheets, online lecture notes and practice questions, and much more!

Beyond calculus, I’ve taught a wide range of math subjects, from Precalculus and Trigonometry to Linear Algebra, SAT/ACT Math, and GRE prep. I’ve also partnered with test prep companies to travel and teach classes worldwide, sharing proven strategies with students from diverse academic backgrounds. When I’m not tutoring one-on-one, you’ll find me teaching college math courses.

What sets me apart is my ability to adapt my teaching style to each student’s unique needs. I’ve worked with students aiming for perfect scores, those struggling to stay afloat, and everyone in between. My goal is simple: to make math understandable, manageable, and—dare I say it—enjoyable.

If you’re ready to see real progress in your math skills, let’s get started. Contact me today, and let’s turn your goals into results.

Excellent tutor for calculus!

Zachary has been a fantastic tutor for AP calculus. He is easygoing, professional, always prepared, and great at explaining calculus concepts (I am a high school senior and he is tutoring me in AP calculus). I recommend him highly!

Excellent and Knowledgeable Tutor

Zachary was outstanding in helping my daughter prepare for the CLEP Calculus exam. He explained complex concepts clearly, guided her step-by-step through the material, and provided focused, strategic training. Thanks to his guidance, my daughter felt confident and did great!

Aruna, 9 lessons with Zachary

GOAT Tutor

Love working with you as always, and I hope to continue our work in and throughout the rest of the year.

Diana, 9 lessons with Zachary

Inspirational and easily digestible knowledge-giver

My experience with Zachary while preparing for my final and attempting to make up for limits and constraints on my mathematical knowledge and skills, was my best tutoring experience ever. Zachary effectively and consistently applied to each concept I had trouble understanding, his method of breaking down and simplifying complicated ideas. Zachary’s support and patience helped me succeed in a class I probably couldn’t have passed without him.

Wonderful support for AP Calculus

Zachary is doing wonders for instilling the confidence my son needs at a critical time when college applications and high intensity school work converges. Much gratitude for hitting the ground running and taking the student with you!

Lifesaver!!!

I was traveling the weekend before a precalc test and really needed help with trigonometry. Zachary was available on short notice and helped me better understand several concepts and gave me tips to help remember certain functions allowing me to solve problems more easily. He demonstrated a strong command of the subject which allowed us to work through many problems together in one hour. After your sessions, I felt much more confident in my ability to do well on my exam. Zachary truly was a lifesaver and his instruction helped me reduce a high level of stress and anxiety I was feeling. Thank you Zachary!

Great experience!

My son said Zachary was nice, knew the material very well, and explained things in a way that he could easily understand. We will be scheduling regular sessions with him!

DESPOINA, 1 lesson with Zachary

Knowledgeable and patient tutor

Great tutor. He helped me pass my pre-calculus CLEP exam with only a few days and I was not even familiar with most of the content. After 9 lessons I felt much more prepared and did indeed pass my exam. He knows his material well and explains it in a clear manner, not to mention he was very patient and wanted to help me when he saw I was struggling. I wouldn't hesitate to come back for another lesson.

Alex, 9 lessons with Zachary

Fantastic tutor

If you need a tutor ditch everyone but Zach. He’s amazing in his instruction and very helpful and prompt as well as professional. Very lucky to have had his help with Calc 2.
