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.

Besides tutoring Olivier loves to create fun and educational online videos, climb mountains, and travel to remote places around the world.

Rafer D.

Rafer has been tutoring math, science, and college entrance tests since 2009. He loves asking questions, such as “so, what do you already know?” or “could we draw a picture?”

Rafer graduated with distinction from Harvey Mudd College with a degree in Mathematical and Computational Biology. From his highly-acclaimed professors, Rafer thinks he learned more about teaching math than actual math. A core tenet: having multiple ways of thinking about a single problem gives a much richer understanding. In addition to math, Rafer enjoys tutoring biology, chemistry, physics, environmental science, introductory programming, and literature, and has an oddly tender spot in his heart for the SAT and ACT.

Outside of tutoring, Rafer likes running. In college, he was a Division III All-American in the 5000 meters, with a 5k personal best of 14:21.
