Tammie Yoakum

Owner
Hello, my name is Tammie Yoakum, and I grew 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.

Aliya Carrera

Hi! My name is Aliya Carrera and I am a 2022 graduate from Pinnacle High School. I've been at Mathnasium for more than 2 years. I've grown so much from my time at the center and I'm excited to see how many lives I can continue to change and improve! Math is a tough subject for many, but I'm here to make it the universal language to all. In my free time, I love to draw/create art, and hang out with family and friends.

Sophia Herget

Hello! My name is Sophia, and I'm currently a junior at Xavier College Preparatory High School. I am on the cheer team there too. I'm also a big fan of any math and sciences! Outside of school, I love music, reading and baking!

Vinnie Caggiula

Hi! My name is Vinnie Caggiula and I'm currently enrolled as a freshman in Computer Science at Arizona State University.

Michael Haradon

Instructor
A life long educator, I taught special education, English as a second language, and the humanities at all grade levels through junior college. Additionally, I have renovated homes, photographed professionally, lived in France and Spain, and was a downhill ski instructor. Currently, in addition to sharing my love of learning with young people here at Mathnasium, I restore old aircraft parts and build models of ships and aircraft with the goal of having my pieces placed in private collections and museums. I am delighted to be a Mathnasium staff member because of my love for helping the younger generations build their math skills and abilities and understand their importance in life, and also because I feel that Mathnasium provides the perfect forum for both teaching and learning math.

Kevin Donnellan

Hello, My name is Kevin and I am a Northern Arizona University graduate. I majored in math since it was always the subject that I found to be the easiest, aside from science. This is my first year here at Mathnasium and I wish to help students understand the language of the universe, and see the beauty in numbers. Outside of my time at Mathnasium, I enjoy playing video games, and going on three to five-mile runs in the Tonto National Forest.
