In his free time, Tommy enjoys drinking coffee, finding new places to eat and exploring different parts of the world!

In her free time, Lepore likes to garden, mountain bike, and read. 


 Chris, Instructor

 Chris is currently studying to obtain his Bachelor's in general physics with a minor in mathematics. Ever since he was little, he's always loved math and science classes. Math was always that class that just came easy to his brain; he even scored a 5 on his AP Calculus exam! He comes from a family of four, not including his two amazing German shepherds. His mom is a teacher's assistant and his dad is an industrial electrician that has pretty much worked everywhere in California. Chirs has a pretty outgoing personality, enough that you might see him actually jumping and running around Mathnasium, but he can be fairly serious when it comes to teaching. His hope is that one day, he'll obtain a doctorate in physics and teach physics at the college level. For now he gets to help all the amazing kids we have learn math, and he thoroughly enjoys it. 


 Ambria, Instructor

Ambria is currently pursuing a Bachelor’s degree in biochemistry at Cal Poly Pomona, and her goal is to use this degree to attend medical school.  She plays soccer for the Cal Poly Pomona women’s soccer team, and as a soccer player has helped to coach and work with kids for several years.  Math is one of her strongest subjects and she's always found herself helping out her peers with the subject.  Since she enjoys helping others learn math, she became a private math tutor in high school and also tutored voluntarily through National Honor’s Society.  She enjoys teaching math and working with kids because it is such a rewarding feeling to help students who were once struggling to become successful.  


Anthony, Instructor

Anthony is currently pursuing his Bachelor’s in Music at Chaffey College. Although music is his passion and career choice, he has had a love for numbers for his entire life. He enjoyed helping his peers with math in elementary school and began privately tutoring students in high school, and his love for teaching has grown ever since. Anthony’s goal is to help kids see math as something fascinating, not frustrating. He believes helping a student understand something they struggle with and seeing them break free of that struggle is one of the greatest joys of being a teacher. He hopes that one day he will have a classroom of his own, and that he will be a positive influence in the lives of all his students. Anthony is an avid tea drinker and likes to spend his free time playing guitar, watching TV, reading, hanging out with freinds, and solving Rubik's cubes!
