Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Geraldine Abinader

Lead Instructor
Geraldine is an IB and AP Calculus certified high school math teacher with experience teaching in both the Dominican Republic and here in the U.S. She loves the logic of math and she loves working with students. She and her husband enjoy the downtown area so much that they decided to move here and make the upstate home. After training extensively at our Woodruff Rd center during our build-out phase, Geraldine is ecstatic to have the opportunity to take the lead at our newest location here on Augusta Road.

Samantha Nusstein

Originally from New York, Sam formally spent 6 years at Buffalo Ski Center as a Lead Ski Instructor. She loves working with kids! Currently, Sam is studying computer science at Furman University. We are thankful she is part of our team!

Jamie Russell

Jamie Russell has a B. A. with multiple teaching credentials from California State University. She works at an online school part-time, homeschools her youngest child and has joined our in-center teaching staff. She and her family currently reside in Easley. An interesting fact about Jamie is that she taught abroad in China for a semester in college!

Heather Robertson

Lead Instructor
Heather Robertson has a B. S. in computer science from the University of South Carolina. Heather has worked off and on at the Woodruff Rd Mathnasium from the first day it opened back in 2016 when she was a high school student! She is fun, smart and fast and kids LOVE her! We are always happy when she returns from her adventures in Hollywood.

Ava Thompson

Online Instructor
Ava is currently pursuing a degree in psychology from Clemson University. She is hard-worker who loves working with kids and is a natural problem solver. She hopes to become a child psychologist and work with kids who have to be hospitalized for serious health issues. During the school year, Ava will be teaching online. She's so much fun! (I think some in-center students will go hybrid just so they can do math with her.) We're so thankful to have her on our team!

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
