 Seetha Jagannath, Math Instructor

Seetha received a Bachelor of Arts in Philosophy from the University of Houston in January 2013 and holds a Master's of Elementary Education at the University of Houston. (2016)

 She has lived in Katy for over 15 years and graduated from Cinco Ranch High School in the top 5% of her class.

Seetha's background in philosophy serves as a strong basis for breaking down various math concepts to students, especially younger learners. She loves working with elementary school students and strives to help them develop their Number Sense and strengthen their fluency with mathematical language.

Ka Ng, Math Instructor

Ka Ng graduated with a Bachelor of Science in Mathematics in the University of Houston in 2012.  One year afterward, Ka went back to UH as a post-bachelor and completed the two years’ program for student teaching. As a certified Texas educator for Math 7th – 12th grade, Ka enjoys helping students review, apply, and build on their math skills, and he also believes that having a strong mathematics foundation is one of the keys to be successful in the future. He looks forward to working with students at Mathnasium.

 Craig Parker, Math Instructor

Craig is a Junior at the University of Houston, where he is majoring Chemical Engineering. While in high school, he competed on both the math and science teams, placing 2nd in the district during his senior year on the math team. He graduated with honors in the top 5% of his class from Cinco Ranch High School. From his time spent competing on the math and science teams in high school, Craig has come to realize the importance of creativity within the realm of logic and reason. For him, teaching math is not just about teaching a straight-forward set of abstract number rules, but also how to manipulate those rules in intricate and useful ways.

 Jorge A. Laris, Math Instructor

Jorge has an Associate's degree in Science, and currently working on a Bachelor's degree in Mathematics at U of H. Has been tutoring math privately since 2006 and believes that math is a subject everybody can eventually understand. Math is logic and problem solving through reasons, not memorization of methods and formulas. Jorge worked mostly with high school students in Algebra, Geometry, but also had tutored college students as well as junior high school students.

Jorge's goal is to become a high school math teacher and wants to help students build a strong math foundation they will need in college.

 Lisa Reynolds, Math Instructor

Prior to earning Texas Educator Certifications to teach Early Childhood through Eighth Grade as well as English as a Second Language (ESL) students, Lisa worked in the energy, construction, and telecommunications sectors. These experiences provide a unique perspective from which she creates differentiated lessons with practical applications.  She enjoys helping students review, apply, and build on math skills, and she delights in finding new approaches to teaching students who may learn math differently.

Nina Boonyaleepun, Math Instructor

 Nina holds a Bachelor of Science in Engineering from Cornell University and a Master of Education from Harvard Graduate School of Education. She is also a former teacher, school administrator, and holds a valid Texas teaching license. Nina enjoys thinking about math through a visual lens and helping students comprehend mathematical concepts in meaningful ways. 

 Ning Lou, Math Instructor

Ning has accomplished a doctoral degree from Lamar University in 2016 and a Master degree from University of Housotn in 2013, both in Industrial Engineering.

Ning has a strong background in mathematics. During his study in universities, he received full scholarships as teaching assistant, where he served as lecturer and tutor helping college students with math-related engineering problems, as well as statistics and probabilities. Ning is obsessed with figures and numbers while he always believes that “numbers don’t lie” and “math is the foundation of any other science”. When teaching, Ning prefers to show “how” instead of merely “what”. He is energetic, friendly, and always eager to help wholeheartedly.

Gagan Kehal, Math Instructor

Gagan holds a bachelor and master’s degree in Computer Science. Before starting at Mathnasium in July 2016, she taught graduate level math related courses at an engineering school for several years.

Gagan strongly believes that math is used in everyday life and aims to make this skill set a strength for all her students. Helping students learn to perform basic functions such as counting money, telling time, understanding fractions and addition/subtraction allows them to utilize these skills daily.  Thus, she teaches students with an objective to help develop their stronger grasp on mathematical fundamentals which thereby sets up a learning stage early on in their career.

 Gagan loves Mathnasium as it provides the right environment and equips all instructors with tools and resources needed to make math learning a fun filled activity. Using proper techniques developed by Mathnasium to teach all aspects of Math makes it lot easier, efficient and productive for students to learn.

Faheem Ershard, Math Instructor

Faheem is an undergraduate student in his third year and is pursuing a B.S. in Biomedical Engineering at the University of Houston. He graduated in the top 5% of his class from Cinco Ranch High School and was active in the math and science honor societies.

As a teaching assistant and facilitator at UH, he has learned that one of the most valuable outcomes of learning math and science is the ability to think creatively and independently. Faheem believes that when students realize that there is always more than one way to solve a problem, students are more likely to find their own, unique ways to solve problems. At the same time, they maintain open minds and build persistence when their methods of problem solving do not work - this is vital in the real world.

Faheem loves working with students of all ages and does his best to be an eloquent and effective instructor at Mathnasium.
