In 1995, Betsy moved to Southeast Missouri where she obtained her teaching certificate and began teaching junior high and high school mathematics. Betsy has 11 years classroom experience in teaching mathematics and has a passion for helping students find success in math. Betsy has also earned a Master’s in Curriculum and Instruction from Western Governor’s University. While in Kansas City, Missouri, Betsy was lucky to be the Center Director for Mathnasium of Blue Valley, a very successful center in Overland Park, KS. This experience fueled a strong passion for the Mathnasium method and helping students make sense of math. Betsy has two grown children, Cole and Riley. They, as a family, recently returned to the Phoenix area and love it. In her spare time, Betsy loves to read, travel, spend time with her family.

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.

Michelle Murray

When I'm not working I enjoy hiking, knitting, and playing videogames.

Mary Latona

Instructor
Hi, my name is Mary Latona and I am thrilled to be at Mathnasium! grew up in the Buffalo/Niagara Falls area of NY where I taught elementary school for 34 years. I decided to relocate to beautiful sunny Arizona after I retired. Teaching is a passion of mine, so I am happy to be back in an instructional setting working with children. In my spare time I enjoy bike riding, playing pickle ball, and traveling with my husband. I have two grown daughters who now live in Florida and complete my family.

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.

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.
