Hear From My Successful Students & Parents

Real results, real transformations. Here's what my clients have to say:

"Calculus felt impossible until I found Jack. After struggling with university resources, a friend referred me to him. Jack immediately helped me grasp tough concepts my professor couldn't, turning hours of confusion into clear understanding. He was incredibly accommodating and genuinely invested in my success, understanding my unique background. Thanks to Jack, I passed Business Calculus with a much higher grade than I ever thought possible!"

— Fletcher, Sophomore, University of Denver (Business Calc)

"Jack was fantastic! He was a lifesaver for my daughter's Concurrent Enrollment College Algebra class at South High. In crunch time, his communication was excellent, and he was incredibly flexible and responsive, even doing extra work on practice problems for her to review before the final. Patient and kind, I highly recommend him! "

— Molly, Parent of College Algebra Student

"Jack is hands-down the best tutor I've ever had! As a student with learning disabilities, I've worked with many; but Jack's clear, concise explanations and unique perspective made all the difference in Calc 1. My notes from our sessions were far easier to understand than my lectures. He was incredibly helpful and flexible, especially during finals, ensuring I was fully prepared. Thanks to Jack, I didn't just pass Calc 1, I achieved one of the highest grades in my class!"

— Ava, Junior, University of Denver (Calc I)

"Jack was fantastic for AP Pre-Calc tutoring! He effectively made up for a year of poor instruction in just five visits."

— Slyvie, AP Precalc Student

"Jack helped my son prepare for a high school placement test. He developed a study plan and taught my son some of the advanced content not covered in his middle school math class. Due to Jack's tutoring, my son placed two years ahead in math. I appreciate both the his skills and how flexible he was in meeting my student's unique needs. This is not a cookie cutter program. He is an expert in supporting students in achieving their academic goals."

Tested into Precalculus as a Freshman — Jessica, Parent of Incoming Freshman

"Jack is phenomenal! My daughter's Trig grade shot from an F to a B in just one month, thanks to his efforts. He effectively drilled key concepts and provided excellent test prep, always making himself available for emergency sessions. We are very happy!"

— Margot, 9th Grade
