Lead Instructor
Josue was born and raised in Los Angeles, and had the fortunate experience to attend UC Irvine, where he learned how big the world is, met my other half, and led and expanded an engineering student organization. After leaving UCI, Josue thought a lot about his future, and he thought a lot about what led him to this point. One thing he'll never forget is his math teacher in 9th grade that didn't give up on him when he was struggling in school. It took Josue a bit of time, but he ultimately decided that he wanted to pursue teaching, and help guide others the same way that teacher did for him. Being an instructor here is Josue's first step, and he hopes to inspire our students and help them learn how vital math is. In his free time, Josue is developing a video game with friends, likes listening to records for hours, and working on various open-source projects.


Kenneth Guevara is a graduate from Cal State University, Dominguez Hills, where he earned his Bachelor’s Degree in Mathematics Education.

Over the years he has tutored many people in math, including classmates, other students, and even some of his neighbors.

Kenneth is very helpful and will help math students understand any areas of confusion or difficulty. In his spare time, Kenneth enjoys reading, bike riding, chess, and video games.


Edgar was born in Pico Union, a neighborhood adjacent to Downtown LA only separated by the 110 freeway. Edgar graduated from USC in 2021 with a degree in Neuroscience and a Minor in French. While at USC, he was a part of the Trojan Marching Band and joined several organizations that aimed to help the surrounding communities. Math wasn’t always kind to him until he made it a personal goal to get better and ultimately he was able to help his classmates. Edgar has always enjoyed working with kids, especially in helping them realize that nothing is out of their grasp and that they are capable of more than they can imagine. During his free time Edgar enjoys playing sports, visiting museums, learning how to dance and going to the beach.


William is a senior in high school and he enjoy many hobbies such as volleyball, video games, and playing the piano. Math has led him to admire so many topics that it branches out to, such as statistics, computer science, and even economics. He has always wanted to become a teacher or professor sometime in the future. Working with students and helping his friends has opened up a new path that he plans on gaining more experience in and participating in for some remainder of my life. William has had the pleasure of receiving an education from skilled and amazing math teachers that inspire me to pursue what he love.


Joseph was born and raised in Koreatown, Los Angeles. He attended the Los Angeles Center for Enriched Studies (LACES) up to junior year before graduating early. During his years as a student, Joseph worked hard to prove himself academically, scoring a perfect 800 on his SAT II: Math subject test, placing first in Academic Decathlon, and joining his school’s NHS program. Since then, Joseph has pursued many different ventures from working in retail management and marketing analytics, to operating and founding several e-commerce businesses of his own, to finally becoming an instructor here at Mathnasium. Currently, Joseph is preparing to go back to school to pursue a new career in law.


Jacob is a senior studying applied and computational mathematics at USC. At university, he takes part in several music groups and participates in the campus hackathons. He actually started his academic journey as a pre-medicine biology major, but after taking math classes such as topology to study how proteins fold, he discovered how much he enjoyed math. He has always appreciated the subject, particularly the realm of discrete math, and is deeply invested in its applications to the real world. Here at Mathnasium, he hopes to inspire a similar interest and desire to learn in his students. During his free time, he produces music and creates digital signal processing applications for audio workspaces. He finds music to be an amazing intersect between math and art.
