CenterDirectorAlex Guppy, Owner

Alex received his Bachelor's degree in Mathematics from Kalamazoo College in Michigan. Shortly after graduating, Alex moved abroad to teach English in Taiwan - an adventure turned odyssey that lasted the next six years. When he was not teaching and having fun with his students, he was exploring the mountains and streams of the island. Eventually, home called and Alex returned to the States in 2013. In the Fall of 2014, Alex visited Chattanooga for a rock climbing trip. As the season passed by and frost began to accumulate on his tent each morning in Prentice Cooper State Park, Alex contemplated returning home to Michigan for the holidays, but then applied for a center director position at Mathnasium to provide math homework help on a whim. He cannot help but look back on his humble beginnings as a math tutor here in amazement.

In the beginning of 2018, Alex became the sole owner of both Mathnasiums in Chattanooga. He is honoured by all of the parents who have entrusted the safety and education of their children to him over the years (and left some fabulous reviews!) and helped him realize his dream of owning his own business. He is looking forward to providing math homework help to many more children in the coming years as he sets up shop in Brentwood, TN to open his third Mathnasium and offer math homework help across the state.

Seth Phillips, Center Director

Seth was born and raised in Brentwood. He graduated from Tennessee Tech with a major in Electrical Engineering. After a brief stint in the field, Seth found that his true passion is working with kids in his favorite subject: mathematics! Seth often tutored his peers in math while he was in high school and he saw first hand the effect it had on their confidence and self-image. He loves that at Mathnasium, he is empowered to give children the instruction and the material that they need to feel confident and successful.

Favorite Number: 8, since it's his birth month and his favorite pool ball as a kid.

Favorite Math Joke: What do you call friends who love math? AlgeBROS!

Fun Fact: Seth played percussion all through middle and high school.

                                         Peyton Nalley, Assistant Center Director

 Peyton is a women's college graduate with Bachelor's degrees in Mathematics-   Economics and Dance. After her undergraduate education, she moved to New York City   to continue dancing. While there, she began tutoring for Mathnasium in the fall of 2016.   She was so taken by the students of the Upper West Side that she accepted a full-time   position following her time at The Ailey School. She had four wonderful years in   management with the Mathnasium of Manhattan team. She's never lacking in funny   student stories to tell! Her favorite part about Mathnasium is seeing students take                                                         ownership of their progress and pride in their accomplishments. 

Favorite Number: 8, because it looks like infinity taking a nap.

Favorite Math Joke: What is a math teacher's favorite vacation destination? Times Square!

Fun Fact: Peyton loves video games and knows every Pokémon by name. 

Chris Guardo, Instructor

Chris is a junior Mathematics major at Belmont University. After he graduates, Chris plans to pursue a graduate degree in Data Science. He loves math because of how factual it is and how it can be used to describe anything in the natural world. 

Favorite Number: Pi, because whole numbers are too mainstream.

Favorite Math Joke: Without geometry, everything is pointless.

Interesting Fact: Chris goes rock climbing and country line dancing in his spare time.

                                      Elle Schaeffer, Instructor

She is originally from a small town in   Georgia where the Master's waterski and wakeboard tournament is held each year. Elle   loves math because it's logical, fun, and has correct answers - unlike writing papers.

 Hobbies: Playing footgolf, drinking apple cider, collecting stickers, and brisk walks.

 Favorite Math Joke: i says to pi, "Be rational." So logically, pi responds to i, "Get real!"

 Fun Fact: Elle pronounces her name L-E, and she's been to Alaska.

Sam Lippe, Instructor

Sam is a senior at Brentwood High School. He loves both math and science and enjoys learning new information. Outside of school he spends time practicing guitar and playing games with his friends and three brothers. Sam's favorite part of his job is observing the change in attitude and confidence kids experience as they gain understanding in math.

Favorite Number: 6, because there are six people in his family. Also, 6 is the first perfect number, which means that all of its factors add up to itself. What's the next perfect number?
