Tammie Yoakum, Co-Owner and Center Director
Hello, my name is Tammie Yoakum, and I few up in Glendale with my sister/co-owner, Betsy. Before I started working in the center fulltime, I had a 30-year career in the premium finance industry. I was blessed to have that career, but Mathnasium is a ton more fun. The best part of being at Mathnasium is to see the "aha" moments and to see a students confidence grow. When I'm not working, I like spending time with my family and friends. I also love music, movies, reading and traveling.

Vishesh Kumar, Lead Instructor
I have always loved math; being an instructor has allowed me to spread that love and help my students. It was with the support of my teachers and tutors that I have been able to excel at math. Now I help others achieve their own mathematical goals. In my spare time, I like to run and play soccer.
Colin McConnon, Lead Instructor
Throughout school, math and physics have always been my favorite subjects. Working through a problem and getting an answer that can be used to figure out how things work in the real world has always interested me greatly. Mathnasium fits in really well with that interest because every day there are kids there that are willing to learn and appreciate math as well. I just finished my first year at Florida State University, where I am double majoring in Astrophysics and Pure Math. I also love to play tennis and basketball.

Blake Kerr, Instructor
Hi! My name is Blake Kerr. When Mathnasium was first recommended to me, I knew it would be a good experience that could improve my life for the better. I get to interact with others, while also getting to develop important skills such as communication and problem solving. One big hobby of mine is robotics, which relies heavily on math. It is always nice to see how math can be used outside of the classroom, similarly to how I use math in robotics. At mathnasium I can help others come to develop an appreciation for math just like I have, and think about it as an important skill rather than just a class in school.

Jonathan Nguyen, Instructor
Greetings! My name is Jonathan Nguyen and I graduated with a B.S. in Biology at the University of California, Riverside. While I was attending UCR, my intentions were to become a pharmacist but then during my junior year, I truly found my passion in teaching! I have experience teaching math and sciences along with ESL (English Second Language). There’s nothing more gratifying than having a student understand the concepts and ideas that I teach them. So I am now with Mathnasium of Desert Ridge to solidify and enhance my teaching abilities to ensure that our students will get the best instruction that we can provide! During my free time, I love to play guitar, watch anime, work out at the gym, and occasionally create lovers of songs that I love to listen to.

Chelsea Leoni, Instructor
I have always had a strong passion for learning, which is why I got my Bachelor's degree in Secondary Math Education from NAU and my Master's degree in Secondary Education from GCU. I like how math feels like a big puzzle, but I really developed a deeper appreciation for math when I discovered my bigger joy for teaching it, which I've done at the high school level for 7 years. I know math is a huge struggle for many students so I love helping kids learn that they, too, can do math and even enjoy it. When I'm not busy teaching, I love going on food adventures, reading, drinking copious amounts of coffee, and working out.
