Center DirectorTommy Najarian, Owner/Center Director

Tommy earned both a bachelor’s and master’s degrees in Mechanical Engineering from the University of California, Los Angeles. After graduating from UCLA, Tommy worked as a Mechanical Engineer and a Technologist in the Aerospace and Defense industry. While attending UCLA, Tommy developed a passion for teaching after tutoring underrepresented college students in the subjects of math and physics. His desire to teach and help the children in his community led him to open a Mathnasium Center.

Adrienne Hulme, Lead Instructor

I am from Portland, Oregon, and after starting college in Texas, finished my Bachelor's Degree in Math from Portland State University.

Favorite Math Joke: The problem with math puns is that calculus jokes are all derivative, trigonometry jokes are too graphic, algebra jokes are usually formulaic, and arithmetic jokes are pretty basic. But I guess the occasional statistics joke is an outlier.

Garett Davis, Instructor

As the only high schooler instructor right now, I’m the baby on the team. But, I’m taking a college level math class and my skills are just as sharp as the rest. As for other things about me: I run varsity Cross Country and Track, am the VP of my school Academic League, and I’m a member of the Model United Nations and Robotics club (basically, I’m a nerd who runs).

Favorite Number:  487 (or any combination of the 3 numbers). I’m convinced the way you write this number tells a lot about who you are.

Favorite Math Joke: Why DID seven eat nine? Because you’re supposed to eat 3 squared meals a day!

In five years, I will be: Pursing my career or going for a Masters degree

I love Mathnasium because: of the level of care put into the students. Rather than teaching them a concept to help them understand in the moment, it's more geared towards building their whole foundation of math knowledge which, most kids skip out on during school. Also, it has a fun environment.

Ray Ruhman, Instructor

I grew up here in San Diego so naturally I'm a huge Padres fan and I have to admit that I'm still a fan of the Chargers even though it still hurts that they left! I also love chess and the occasional tennis match. It's really a beautiful thing when playing a tennis game feels like playing a chess game and vice-versa. The two games are so different yet have so much in common it always amazes me. I became interested in math when I was introduced to the concept of imaginary numbers and my fascination grew from there.

Favorite Number:  My favorite number is 8 because it's always been my lucky number and I can remember as a very young child learning to write numbers and thinking that it was the coolest one.

Favorite Math Joke: A statistician almost drowned while attempting to cross a river. By his calculations it was three feet deep on average.

In five years, I will be: A better chess player!

I love Mathnasium because: It's a great environment that illustrates how fascinating (and useful) mathematics is. Helping others uncover some of the mysteries of math is extremely rewarding.

Richard Aubert IV, Instructor

I am a freshman studying Electrical Engineering at SDSU. I was born and raised in El Paso, Texas, and have a younger sister and brother back home whom I miss very much. In high school, I spent half of my time playing the Saxophone in the marching band and jazz band, and the other half was spent playing Basketball. With a degree in electrical engineering, I hope to improve on our use of solar panels and other alternate energy sources.

Favorite Number: 32, Because that was my basketball jersey number throughout high school.

Favorite Math Joke: Why do mathematicians like parks? Because of all the natural logs.

Travis Nielsen, Instructor 

I love math and music. Jazz and math rock are my favorite genres of music. Topology and Optimization were especially interesting while I earned my math degree.

Favorite Number: 5/4. It’s a really special music signature that many jazz standards are based off of.

Favorite Math Joke: Negative.

In five years, I will be: Helping math become understandable to a new generation in my classroom and at Mathnasium.

I love Mathnasium because: Mathnasium brings students to central location to focus on math. This gets them out of their comfort zone and helps them build motivation both in success, but also in during their rough times.
