Malcolm Weldon, Center Director 

Holds a BS in Mathematics. I started out as an instructor in 2013, eventually working my way up to Center Director of Rancho San Diego West. I believe every student deserves a chance to succeed & Mathnasium gives this opportunity to every single student that walks in the door. I love that we make a subject that a lot of students find difficult, fun & exciting! In my spare time, I enjoy spending time with my dogs: Koda, Shadow, Snoop, Sherlock & Gohan. And if im not doing something involving them, I am usually eating some kind of asian food!

Favorite Number: -1 b/c it’s equal to e to the í pi & all 4 of these numbers in their own right are special, but to put all of them together is something really unique & awesome.

Favorite Math Joke: Why did I divide sin by tan? Just cos...

In five years, I will be: Continuing my love of getting students to love mathematics through the awesome program that is Mathnasium.

I love Mathnasium because: Of the methodology. I love the way we make math make sense to our students. The world will be a better place with more mathematicians and scientists, I believe. So if we can get them started early who knows what we can inspire.

I love Mathnasium because: It provides a fun and interesting way to teach a subject that most students find boring.

Marti Glovinsky, Instructor


Mickey Sieveke, Instructor

Mickey retired from the United States Navy in 2014, and is currently pursuing a degree in Mechanical Engineering from SDSU.  When not at Mathnasium, or doing school work, he spends his time with his wife and their two kids.

Favorite Number: Pi.  Who doesn’t love pi?

I love Mathnasium because:  I’ve always believed that there is no such thing as a bad math student, rather, math difficulties arise from poor communication on the teacher’s part.  I like that Mathnasium instructors strive to help kids breach that communication gap, bringing the child to an understanding of the concepts behind math.

Omar Ortuno, Instructor

I'm an outdoor kinda guy. I enjoy math because I see it as a puzzle/game. I enjoy playing with my dogs and I am doing my best to clean up this world for future generations to thrive.

Favorite Number and Why: My favorite number is 24 because it is the number of hours in one whole day, and one day is all you need to make a difference in this world.

Favorite Math Joke: What do baby parabolas drink? Quadratic Formula.

In five years, I will be: Working as a Mechanical/Aerospace Engineer for an Aerospace Manufacturing Company.

I love Mathnasium because: It makes kids want to learn math. They shouldn't be scared of math or dislike it.

Rami Awakeem, Instructor

I am an undergraduate student at University of California: San Diego majoring in Human Biology. I have and probably will always love mathematics. I am an aspiring doctor, more specifically a surgeon. In my free time I binge TV shows and movies on Netflix, play video games, read scientific journals and articles, and spend times with my friends.

Favorite Number and Why: My favorite number is 5 because it’s the easiest number to work with that doesn’t have a one in it (which is boring).

Favorite Math Joke: What do you call a perfectly round gentleman?

In five years, I will be: In a Med School somewhere, hopefully UCSD.

I love Mathnasium because: Not only do they provide support for students who are both excelling and struggling in math, but they also provide a genuinely pure and friendly environment. The program also teaches math in techniques and ways that are very unique and effective.

Robert Arreola, Instructor

San Diego native and former high school math teacher of 22 years. I taught every math subject from Algebra to AP Calculus and AP Statistics. I love math because it is logical and there is always an answer with many different ways to get to it. I am a cactus and succulent lover in my spare time.

Favorite Number and Why: Not sure I have one, but I do have a favorite equation. e^(i*pi)+1=0. So beautiful!

Favorite Math Joke: How many kinds of math teachers are there? Three. Those who can count and those who can't.

In five years, I will be: Getting close to retirement, maybe. Definitely trying to enjoy life more.

I love Mathnasium because: I am able to continue to help students improve their understanding of math and help them improve their skills. I also like the fact no two days will be alike because I get to interact with different students on whatever skill or concept they are currently working towards mastery.
