Our specially trained math instructors will teach your child how to understand math in an individual setting; our unique approach enables us to explain concepts really well and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn! Read below to learn more about our talented team:

 Andrew, Center Director 

Andrew graduated from UCSD with a degree in Mathematics. His student observations, parent consultation abilities, understanding of Common Core and Integrated Math expectations, while bridging kids from elementary through middle school to high school make him an outstanding resource for leading the center in student growth of math skills and problem solving.

Cynthia, Lead Instructor 

Cynthia studied aerospace engineering at UCSD and has worked at the Boys and Girl Club with their youth programs. Cynthia also serves as Mathnasium of La Jolla's Lead Instructor. She manages student progress and curriculum for each of our mathletes.


Vivian, Instructor 

Vivian attends UCSD and has not only worked in our center, but a Mathnasium in Irvine as well. She has tutored at both the high school and collegiate level. Vivian prides herself on her excellent communications skills as she balances simplicity with thoroughness. Her favorite part about working with kids is making them feel happy while remaining focused. That is the perfect recipe for our Mathnasium instructors.

Kaylin, Instructor

A UCSD student from NorCal, Kaylin is very approachable and makes "hard" parts of math easier. She joins us with prior Mathnasium experience having worked at Mathnasium of Cypress (CA) previously.  She is patient and supportive, and able to transition from our younger friends to our older ones.


Ivan, Instructor 

Ivan is a first year at UCSD and loves working with students of all ages, but especially our high school kids. He is terrific with the integrated math program and stays ahead of the pack by studying their upcoming chapters so he is completely familiar with what the kids are learning in school. 

Helena, Instructor 

Helena is a math major at Mesa College when she also served as a math tutor. She is also taking educational course at UCSD. This is the perfect combination for our mathletes!

Karen Lossing, Owner 

Karen is the owner of Mathnasium of La Jolla. Prior to opening her center, Karen worked as a 3rd, 5th, and Special Education teacher, math curriculum writer, and elementary school administrator, focusing on 21st Century learning.  Karen has always loved math, and upon relocating from Texas to California, jumped at the opportunity to spend her day working with kids to make them more successful in the subject. Karen is enthusiastic about her team helping children in the La Jolla communities to truly understand math by teaching it in a way that makes sense to them. You may reach out to her any time with any questions. She is actively involved in our center.

Libby, Director of Operations

After a couple years of being a seasonal instructor in our center, Libby recently graduated from UCLA and has joined onto our team as the Director of Operations. While she is no stranger to the instruction and tutoring aspects of our center, Libby focuses on the community involvement side of our center. So if you have any school events or sponsorship opportunities you would like Mathnasium of La Jolla to be involved in, Libby is your girl!
