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.

 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.

 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.
