Meet The Team

Brooklyn Math Tutors was founded with a simple guiding philosophy: Make math fun, the process of learning enjoyable, and the rest follows.

To that end, Brooklyn Math Tutors seeks out teachers who are not only strong in math, but are also warm, well-rounded, dynamic human beings, able to inspire and connect with their students on an individual level.

Alexander Friedman – Founder

Alex has enjoyed tutoring math, science, and other technical topics since he was a teenager at Stuyvesant High School.

He graduated Summa Cum Laude from Northeastern University, worked as a Researcher at Carnegie Mellon, and did a brief stint as a technology consultant before leaving the corporate and academic worlds to tutor full time.

Having worked with kids, adults, and everyone in between, he came to see that math-phobia, uncertainty, and boredom – not a lack of innate talent – keeps most students from succeeding.

Kieran O’Hare

A graduate of New York University, Kieran is a teacher and tutor with over ten years of experience working with students from elementary school through college. While in college, Kieran worked for a work-study program called America Reads in a New York City Elementary/Middle School, and was hired by parents to tutor students outside of the classroom as well.

Kieran worked at Laguardia Community College in the Office For Students with Disabilities, where he conducted one-on-one sessions in Algebra 1 and 2, and Geometry. He continued at Laguardia afterwards, becoming a classroom teacher in the Adult Basic Education program where he prepared students for the CUNY math entrance exam.

Kieran aims to improve his students’ skills by making them think critically; he uses a question-based approach so that students can take what they do together with Kieran in tutoring sessions and apply it to situations independently. Kieran believes that no two learners are exactly alike, and as such, he provides a unique tutoring experience for each student, rather than a “one size fits all approach.”

Outside of teaching, Kieran enjoys running, illustrating and animation, reading, and watching EPL soccer.

Tom Fogle

Cindy specializes in tutoring students in ELA, Spanish, and SHSAT (and other tests) prep, as well as in helping students with their organizational skills. Being an English teacher is the proud fulfillment of one of her lifelong dreams. Her long-term goals involve finally knitting something beyond the size of a pocket square, learning to love tea, and owning a functioning typewriter.
