Center Owner and DirectorSam Younis, Center Owner

Sam is thrilled to launch his third Mathnasium center in Morningside!

Sam graduated Cum Laude from Vanderbilt University, where he studied the social sciences and gained a deep appreciation for math and statistical analysis. He then earned an MFA in Theater from Columbia University, where he nurtured his creative side. Prior to owning Mathnasium, Sam has worked as an actor, writer, public servant, and tutor. As an actor, Sam has appeared on Broadway and in television and film. As a top-level field operations manager for the 2010 US Census, Sam collected and analyzed statistical data that would later become official 2010 Census records.  In 2012, Sam opened his first Mathnasium center in Los Angeles before moving to Georgia with his family two and a half years later.  Now firmly rooted in Georgia, Sam is also the owner of the Mathnasium centers in Decatur and Dunwoody.  He has served on the Mathnasium Franchisee Advisory Committee, which helps guide Mathnasium Headquarters as it makes key decisions about the direction of the company.  His center in Decatur is consistently ranked among the top 40 out of 1,000 centers in the country and also earned an award from Mathnasium Headquarters for outstanding growth in its 2nd year of operation.   An advocate of both math and the arts, Sam is passionate about the Mathnasium Method because it enables kids to apply creativity to the understanding of math. It is his mission to help kids develop an excellent number sense and have fun along the way!


Logan Austin, Center Director

Logan grew up in Peachtree City, Georgia and has always held a deep love for mathematics. He later attended the University of Southern California's prestigious film school, graduating with a degree in screenwriting. He's worked in a variety of capacities in the film industry, writing, directing, gaffing, and composing music. He recently wrote, performed, and recorded the original soundtrack for the 2019 film THE LAST WHISTLE, now available on Netflix. Living in Grant Park, he can be found most days cycling, writing music, playing chess, or running operations at Mathnasium of Morningside.


Claire Kuykendall, Field Support Specialist

Claire joined the Mathnasium team in the summer of 2015 while she finished up her time at Georgia Tech where she majored in Applied Mathematics with a minor in Environmental Science. After graduation, she continued working at Mathnasium until she left for her post-graduate studies at the University of Glasgow in Scotland where she studied Environmental Statistics. Claire's love of math and helping others find their love of math brought her back to Mathnasium when she returned from her studies abroad. Outside of Mathnasium, Claire can be found at a concert, obsessing over all things Swedish, or binge-watching shows of Netflix.


Cody McCord, Lead Instructor

Cody is from a little town near Athens, Georgia, but - much to the disappointment of his peers and family - decided to attend Georgia Tech. He graduated in 2016 with a Bachelor's in Biology and a minor in Physics. Outside of Mathnasium, Cody is a physics research assistant where he investigates how top quarks are produced in hadron colliders (like at Fermilab and CERN) and how the atmospheres of exoplanets behave when in close proximity to their host stars. He is very passionate about math and physics education and hopes to one day teach university-level physics. When he's not at Mathnasium or doing research, you can most likely catch him reading, hiking, or eating.


Sean Kearney, Instructor

Sean is a senior at Georgia Tech, studying Mechanical Engineering. He transferred from Georgia College and State University, where he studied and tutored physics. In his free time, Sean enjoys cooking, playing guitar and hockey. 



Cole McCord, Instructor

Cole is a senior at the Georgia Institute of Technology, majoring in Computer Science with concentrations in Networking and Media. When he's not at Mathnasium or in class, you can catch him listening to music, hiking, or eating.

Sarajane Crawford, Instructor

Sarajane is a fourth-year at Georgia Tech, studying Aerospace Engineering with a minor in Computing and Intelligence. She is very passionate about outer-space and loves that mathematics can be used to describe the motion of the planets. Therefore, she is very grateful for the math education that allowed her to understand orbital mechanics. Outside of Mathnasium, Sarajane writes flight software for an upcoming cube satellite mission and serves on the executive board for GT's Women of Aeronautics and Astronautics, which promotes women in STEM. In her free time, she can be found playing soccer, doing yoga, or running in Piedmont Park.
