Karen Roussos and her family have lived in Southlake for over 7 years. Karen has a degree in Electrical and Computer Engineering and has worked for companies such as Intel Corporation and Texas Instruments. She is also an entrepreneur and has started other successful small businesses. They have 3 children in the Carroll ISD.

Karen is very excited to bring Mathnasium to Southlake and make math enjoyable and challenging for your child and convenient for the parent. Karen believes that once a student truly understands and masters the key concepts of math, they will gain confidence in their math skills and increase their problem-solving and critical thinking skills.

We will help your child in our center, not send them home with more homework!

Meredith Jones and her husband live in Roanoke. Her two greatest passions are math and their dog, Sam. Meredith studied Meteorology at the University of Oklahoma for two years, and then decided to earn her degree in Mathematics in order to teach. She has taught 9th Grade Algebra I and tutored for many years.

Meredith is overjoyed to have the opportunity to share her passion with children of all ages. She loves explaining why things work the way they work and boosting every child’s self-confidence. She feels so blessed to have a job that she is so passionate about.

We are here to develop a child’s number sense and fluency; we will never answer a question with, “because I said so.”

Jacob has positively leapt at the opportunity to help children improve their math skills. He greatly enjoys relating the subject to important parts of his students’ everyday lives. More than just helping kids do homework, Jacob wants to show them how to solve problems.

Math leads to logic, logic leads to reason; reason leads to happiness.

Rick was born in Iowa and spent most of his childhood moving back and forth between Iowa and Minnesota. He and his wife have a 17 year old senior who loves his drum set, and a 16 year old sophomore who loves her French Horn (although he could swear it has a German accent to it!!) He remembers sitting in 9th grade Algebra class in a small town in Iowa looking at his Math teacher/Football Coach, thinking, “How can such a cool guy end up being a math teacher??” He then went on to earn a degree in chemistry with minors in physics and – you guessed it – MATH! He has taught high school physics, geometry, algebra, algebra 2, chemistry, environmental science, and physical science. He also teaches rock climbing and repelling, loves to scuba dive, and do a host of other fun and cool stuff.

Along the way, Rick has helped to direct a Christian adventure camp in Wyoming, having played guitar for over 40 years – even professionally, and being in a band voted best band in Tarrant County by the Star Telegram readers in 1999-2000. He has also been a youth and worship pastor, and is now a high school assistant principal turned district coordinator of technical projects. He is nearly finished with his PhD in Curriculum and Instruction, and will have a minor in statistics.

Fun Fact: Rick has 4 dogs, 2 cats and a snake? (no, we are not kidding!)

Fred recently moved to Southlake from the Midwest with his fiancé, Karen, and several four-legged creatures! For 40 years, Fred taught High School Mathematics, coached Basketball, Football and Track and loved every minute of it! By teaching in a very small community (800 residents), over time, Fred was teaching the children of his former students. One could rarely go anywhere in town without meeting someone who had been in his class.

After “retirement”, something felt wrong. That wrong was righted when Fred went back to teaching math at Black Hawk Community College. Now that he has moved to Texas and connected with Mathnasium, Fred feels very much at home being able to teach and inspire a new group of eager, junior mathematicians!
