Kim Breitenbach

Center Director

Hi, My name is Kimberly and I am the Center Director at Mathnasium of Westwood-River Vale.

I have a background in education dating back to 2014 and have dedicated my time to helping students achieve academic success while reaching their full potential. I take great pride in witnessing the growth and increased confidence of each student as they catch up, keep up, and get ahead.

Eli

Lead Instructor

My name is Eli, and I’m the Lead Instructor at Mathnasium. I’m currently a junior at Montclair State University, majoring in Computer Science. I’ve always had a passion for both mathematics and helping others, which made Mathnasium the perfect fit for me. I started working here as a junior in high school, and now, as I continue through college, I’m grateful for the chance to inspire students and help them gain confidence in their math skills.

One of the most rewarding parts of my job is getting to know each student as an individual and connecting with them beyond just math. I see them as more than just students in a classroom—I see their unique personalities, goals, and talents. Building those connections makes it even more fulfilling to watch them grow, not only in math but in confidence and self-belief.

When I’m not working or studying, I enjoy playing video games and listening to music, which help me recharge and stay creative. Mathnasium has been an incredibly rewarding part of my journey, and I love being able to make a difference in students' lives every day. Seeing their growth and enthusiasm reminds me why I’m so passionate about what I do.
