 Shadia Rameh, Center Director                 

Shadia has been teaching and tutoring Mathematics for more than 25 years, in French as well as in English. She is well-versed in all levels of math and has taught both regular and honors courses. She holds a Bachelor Degree in Mathematics and Education from the American University (overseas) and has pursued Master's Studies in Education from Lesley College. Throughout her career as an educator, she has always had a passion for teaching, tutoring, and cultivating positive relationships with students. She looks forward to working with students of all ages at Mathnasium of Hancock Park! She is now not only a teacher at Mathnasium of Hancock Park, but she is also the Center Director.


Aaron Anthony, Instructor

 Aaron Anthony graduated from UCLA with a bachelor’s in Math Economics. He is working toward a masters in Financial Engineering. He served as a Los Angeles Valley College Math Center tutor for 2 years at LAUSD. He has been a swim instructor for LA City pools for 5 years. He is  also a PE coach  at the Jewish Community Center.

How would you multiply 999 x 3? While this can be computed on paper using the standard multiplication algorithm, a deep understanding of multiplication reveals the answer is 3000 – 3 = 2997. Aaron loves working at Mathnasium because the method here does its best to develop the mathematical intuition behind the numbers.

Small errors may lead to dead ends in the world of math. Yet math is full of great roads built by Euler, Pythagoras, Leibniz, and Newton. As an instructor, he paves the roads by making the material clear and presentable. This is why he finds teaching math very rewarding. Bring your child and let him/her enjoy the center!                                                   


                                                           Jake Bohringer, Instructor

Originally from the Chicago suburbs, Jake moved to Los Angeles in 2018 to pursue his Bachelor's degree at the Gnomon School of Visual Effects in Hollywood.

In addition to his artistic pursuits, Jake has always liked math and loves to work with students. Previously, he instructed at all levels at Mathnasium of Downers Grove, IL for almost a year.

Marta De Cardenas, Instructor

Marta De Cardenas is pleased to share her knowledge and love of math with the Hancock Park Mathnasium students as she does with her own students at St. Paul the Apostle School. She currently teaches Pre-Algebra at St. Paul the Apostle in Westwood and has been a middle school math teacher at St. Paul since she moved to Los Angeles in 2010. 
In addition to math, Marta has taught reading, language arts and theatre arts, among many other subjects since she first became a teacher in 1998.  In 1994, she earned her degree in theatre arts from Florida State University, and continues to this day to nurture her artistic pursuits, writing and acting for film and theatre.  Nevertheless, when it comes to core school subjects, math has always been her favorite, and she hopes it will become the favorite of Mathnasium students too.
