Jessah Banayo

Lead Instructor

I graduated with a degree in Bachelor of Science in Applied Mathematics. I specialized in Operations Research mostly dealing with studies regarding Bee behavior. I previously worked as a private tutor in a local tutorial service during the pre-pandemic era for 10 years where I gained experience and skills on teaching junior and senior high school students on different branches of Mathematics. My passion for teaching keeps me motivated to hone more talents and make students appreciate Mathematics.

Jomhel Agnote

Instructor
I am a graduating BS Applied Mathematics student. I major in Financial Management and Actuarial Science. I started tutoring when I was in my 1st year of college, and I have been a tutor for almost 9 years. I love when I see my students improve and be independent. I am passionate in everything that I do, that includes guiding and helping my students. I love playing guitar and learning other musical instruments in my spare time.

Sara Ortiz

Lead Instructor

I am currently a Senior at California State University Dominguez Hills majoring in math education and will be working on getting my teaching credential. Math was my favorite subject growing up.
It’s important to me that these children don't only come in here for math, but also come to feel comfortable enough to ask for help and boost their confidence in their math skills, since it can sometimes be difficult to do that in larger classroom settings.
Fun fact about me: when I was 7 years old, I asked for a calculator for Christmas
