Claire Snyder, Assistant Director 

Claire is an avid lover of Algebra who jumps at every opportunity to help others enjoy it as much as she does. Her love of math started at an early age and has carried her to London where she studied Advanced Mathematics at the University College of London. She has a bit of a travel bug and loves visiting Japan, but she always finds herself coming back to her first love – math. She hopes to be a positive force at Mathnasium and spread the word that math can be quick, easy, and – most importantly – fun!


Zachary Adams, Lead Instructor 

Since Zachary was young, he has always enjoyed math and science. When people asked him what he wanted to become, he would say an astronomer because he wanted to study and understand the stars. Zachary graduated from UC Santa Cruz with a degree in Astrophysics. He also loves to travel and experience new places. He has gone on trips to Europe and South America. Zachary is looking forward to the opportunity to share his enthusiasm for math and problem solving as an instructor at Mathnasium.


Jeremy Hoffman, Instructor  

Jeremy is the very first instructor here at Mathnasium of Novato. He loves to teach the logic behind math, from why you cannot divide by zero to how a triangle can explain the formula A=πr². In addition to teaching at Mathnasium, Jeremy is pursuing degrees in computer science and psychology. He also enjoys creating educational apps, board games... and writing about himself in the third person.


Phil Klempner, Instructor 

When Phil was young, he discovered math through Bell’s “The Queen of the Sciences”. He received his degrees in theoretical physics and mathematics in South Africa. Phil taught remedial math and then later worked in electronics. Plato’s remark, “What does one know of math, who only knows math” led him to meditate in India and develop the understanding that one needs to share what one has to live fully. So, a main direction for him now is to share how to move from cannot to can in math and otherwise.


Elena MacDonald, Instructor 

Though new to Mathnasium of Novato, Elena is a Mathnasium veteran having worked at the Roseville center while earning her degree in Elementary Education at Sacramento State. Since then, she has served in the Peace Corps teaching primary English literacy in the Eastern Caribbean. Happy to be back with the Mathnasium team, she is a true believer in the Mathnasium Method and determined to pass on the love of math to her students.


Samantha Tapia, Instructor 

Samantha began her university career studying art in Maryland. She always had an equally strong interest in science. This influenced her aesthetic sensibility and the subject matter of her artwork, eventually leading her to leave art school and complete a B.S. in Mathematics at Arizona State. She’s eager to share what she has learned in her creative math explorations and show students that math can be an imaginative, visual process as well as an abstract, analytical one.  


Dennis Lee, Instructor 

Dennis is a student currently attending Novato High School in his sophomore year. He has a driving motivation to excel in math and enjoys it as he is fascinated by the logic and reasoning behind all the expressions, equations, and formulas. His interest in teaching the subject comes from school where his classmates ask him for assistance when they do not understand an assignment. Through this he discovered that he was quite good at helping his peers understand the subject and found it to be quite satisfying to tutor others. When he heard that there was an opportunity for him to teach at Mathnasium he quickly pursued it.


Eric Douglas, Instructor 

Standing at 6’5”, Eric never played basketball, but could tell you about the geometry behind it.  He is a recent graduate from Humboldt State University with a degree in environmental resources engineering.  One of his goals is to show as many people as possible that math is not something to be feared, but a challenge to enjoy.  During his downtime, Eric enjoys backpacking, taekwondo, and writing.
