Zelda is an educator with 10+ collective years of experience as a tutor, private high school teacher, college advisor, and sports coach. Born and raised in New York City, her family moved to sunny Los Angeles the fall before her 7th grade year. After attending Harvard-Westlake, she matriculated to Princeton University, where she received a bachelor’s in English, along with an ethnic studies certificate. Shortly after, Zelda attained her high school teaching credential and Masters in Education from UCLA before teaching at New Roads School in Santa Monica. Zelda tutors the HSPT and the ISEE, in addition to academic support for middle, high school, and college students. Some areas of expertise include English literature, middle school science and math, study skills, essay writing, and organizational support.

Zelda’s teaching style is one of empowerment – she strives to catalyze newfound confidence in her students as they learn. Her approach is to demystify and illuminate, breaking down challenging concepts into bite-sized chunks, and highlighting effective strategies to build proficiency.

In her free time, she composes sax, flute, and trumpet parts for neo soul music. Outside of that, she’s just a friendly neighborhood sci-fi nerd, and can often be found chatting endlessly about her love of works like Star Trek, the MCU, and pretty much any film with time travel. Zelda is available in-person and remotely via Zoom.

Gabriel Moussaoui is finishing his M.S. in Applied Mathematics at California State University,
Long Beach in May 2026, and earned his B.A. in Pure Mathematics from the University of
California, Irvine in June 2020. He specializes in tutoring Algebra I, Algebra II, Geometry, pre-calculus, Calculus, and AP Calculus AB/AP Calculus BC. He has nearly a decade of experience working with students in tutoring and classroom support roles, and he enjoys helping students work through subjects that can feel intimidating at first.

He especially likes tutoring math because he knows how frustrating it can be when something
just does not click right away. He tries to break things down clearly, be patient, and meet
students where they are so they can build both understanding and confidence. His goal is not
just to help students get the right answer, but to help them feel more comfortable with the
process of learning and problem-solving.

Gabriel wants students to feel like they can ask questions freely and not be judged for what
they do or do not know. He believes that a good learning environment makes a big difference,
and he does his best to make sessions feel supportive, clear, and productive. He wants students to leave each session feeling more capable than they did before.

In his free time, Gabriel enjoys playing video games, listening to music, and spending time
exploring personal interests in technology, math, and creative projects. He likes activities that
help him unwind while still keeping his mind engaged, and he brings that same curiosity and
energy into the way he works with students. He is available via Zoom on weekdays and in-person on weekends.

Erik holds a master’s degree in mathematics from California State University, Northridge, where he graduated with distinction and a perfect 4.0 GPA. Over the past decade, he has taught and tutored math across all secondary and undergraduate levels, from algebra and calculus to linear algebra and differential equations. His primary tutoring experience comes from tutoring all college-level math classes for 6 years at Los Angeles Valley College math tutoring center. He has also tutored at Mathnasium for 2 years, where he had an opportunity to work with students from secondary school in a 3-to-1 student-to-tutor ratio. His tutoring experience is heavily augmented by countless private tutoring sessions both in-person and online, especially during the pandemic.

Through these years, he’s found that students thrive when instruction is tailored to their unique strengths and areas for growth. He has also found that mathematics can be overwhelming with concepts, notation, and abstraction. To mitigate these challenges, he explains sophisticated mathematical concepts in plain and understandable language and, possibly, with reference to the area of student’s interests. His tutoring sessions are highly student-centered: He focuses on identifying and addressing individual challenges, while reinforcing core strengths to build confidence and mastery. He strives to create a supportive, structured, and engaging learning environment that empowers students to overcome obstacles and reach their academic goals.

He welcomes any insights or resources from students and parents that can help make our sessions even more effective. He is responsive, approachable, and always ready to support learners on their journey toward mathematical confidence. He is available in-person or via Zoom.
