My name is Riss Mendizabal! I was born in Matanzas, Cuba and grew up in Miami and graduated from Ransom Everglades. Education is something I have always been passionate about. As a former instructor for Breakthrough Miami, I know first hand the importance of a strong mathematical foundation in children's lives. In my off time, I enjoy cooking and spending time with my 7 year old lab, Lenny.
Jenny has been part of the Mathnasium team since 2013 and is passionate about making math meaningful for every student. She holds a degree in Math and Sociology from the University of Miami and believes that students learn best when encouraged to find their own problem-solving approach.
Her favorite part of the job is watching confidence grow and seeing those “lightbulb” moments when a student finally connects with a tough concept. Jenny is committed to ensuring that every child feels supported and capable in their math journey.
Elizabeth brings both insight and heart to her role as Director of Operations at Mathnasium. She holds a bachelor’s degree in Psychology from Florida International University and uses her understanding of how children think and learn to support effective instruction and team development across centers.
As a proud mom of two boys, Elizabeth knows firsthand the value of confidence-building education. Whether managing operations or creating a positive learning environment, she believes in the power of patience, encouragement, and a well-timed snack.
Laura is committed to making math approachable for every child. She holds a BS in Business from Wake Forest University and is raising three sons who remind her daily of the importance of education. She and her husband Jonathan opened their first Mathnasium center in 2014.
Since then, Laura has played a key role in creating welcoming learning spaces where families feel supported and students thrive. Her passion for helping children grow and succeed makes her a vital part of the Mathnasium mission.
Jonathan holds a BA in Economics from Wake Forest University and earned an International MBA through a joint program with the University of South Carolina and Wirtschaftuniversität Wien in Austria. With nearly two decades of experience in finance, he brings deep insight into the long-term value of strong math skills.
A runner and former lacrosse player, Jonathan sees math mastery much like athletic training—built through practice and discipline. He enjoys working with children and volunteers as a lacrosse coach for his sons' team, combining his love of education, sports, and community involvement.
Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.
