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.

Mila Liakhovitser

Originally from Bronx, NY, Mila is a graduate of Bronx Science where she took every single math course available starting with honors precalculus her freshman year. She discovered her passion for tutoring as friends started asking her for help with their math classes. She’s tutored all levels of high school math including Algebra I, Algebra II, Geometry, Trigonometry, and PreCalculus.

After scoring a 2380 on her SATs (800 math, 790 reading, 790 writing) and conquering the SAT IIs (math I 800, math II 760, literature 730), Mila made the SATs her specialty, teaching the test as well as uncovering and fixing knowledge gaps along the way to best prepare students for college.

A tutor of 10+ years, she prides herself on her ability to connect with students and understand their needs. Everyone learns and approaches problems differently which is why she takes the time to understand her how her students think so as to explain concepts to them in a way that clicks for them; the great thing about math is that there’s always more than one way to solve a problem! She also understands that self-confidence is half the battle and shows her students how much they already know rather than just pointing out their problem areas.

Mila graduated in 2015 from Duke University with degrees in both mathematics and philosophy and a minor in economics and has since worked as a business analyst and financial data analyst for multiple banks on the East Coast. She hopes to get her Masters in Data Science and continue her analytical journey, all the while tutoring the subject she loves best (math, duh!).

Cindy loves reading, writing, teaching, baking, coffee, lemon seltzer, sunshine, oceans, photography, chocolate chip cookies, candles, grammar, the Harry Potter series, Brooklyn Nine-Nine, semicolons, alliteration, puppies, writing in cursive, singing, the month of December, and, somewhat regrettably, the Mets; she believes they give her resilience and a persistent optimism that cuts through the pervasive misery they also cause her.

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.
