Tammie Yoakum

Owner
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.

Katie Rendon

Assistant Center Director
Hello! My name is Katie Rendon. I am the Assistant Center Director of Mathnasium of Fountain Hills. I have a Bachelor's Degree in Secondary Education (Earth and Space Sciences) from Arizona State University. I am an avid reader, puzzle enthusiast, and a big Disney fan. I believe it is very important for a student to understand why they got their answer, so they can apply that knowledge to future problems for continued success. I look at math as a puzzle that I can solve with the proper tools and strategies.

Lan Quan

Instructor
My name is Lan Quan and I have been a homeschool teacher for the past 20 years. I graduated from Arizona State University with a Bachelor's degree in Electrical Engineering and worked in the semiconductor field as a test engineer. In my free time, I enjoy growing organic vegetables in my garden as well as learn how to make healthier meals. My husband and I are blessed with four children that we decided to homeschool. I taught them math from elementary to high school level and they all received high scores on the SAT. I also taught a SAT math prep course for the Fountain Hills Christian Home Educators group. Throughout two decades of homeschooling, I've seen that every student learns math differently according to their learning style. It will be my honor to join the Mathnasium team to help students conquer and master all levels of mathematics.

Kevin Donnellan

Instructor
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.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
