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.

Zack Moore

Assistant Director

Zack is currently pursuing a degree in Computer Science through Western Governors University. A lifelong Potomac resident, he loves working with students and making math approachable and fun. 

His favorite numbers are 5 and 8, and he’s known for using exactly that many cloves of garlic in his cooking. Zack enjoys hiking, tinkering with home servers, and gardening. He speaks English, some Mandarin, and is learning Korean.

Constance Sutter

Instructor

Constance is pursuing her Master’s in Clinical Mental Health Counseling at McDaniel College and holds academic backgrounds in mathematics, psychology, and philosophy. She loves connecting with students and helping them grow through math. 

Her favorite number is 7 because of the cool repeating decimal patterns it creates. She speaks Greek, and in her spare time, enjoys weightlifting, reading and writing, and playing music.

Michael Holder

Instructor

Michael is a student at Winston Churchill High School with plans to study Mathematics, Engineering, or Finance in college. He enjoys helping students grasp challenging math concepts in a supportive environment. 

His favorite number is 1, for its versatility and foundational role in math. Outside of school, Michael runs track and cross country, plays the drums, and loves watching movies.

Ryan Cheriathundam

Instructor

Ryan is an 11th grader at Walt Whitman High School considering a future in chemical engineering or computer science. He enjoys making math fun and relatable for students of all ages. 

His favorite number is 8, a nod to both Alex Ovechkin and its status as a doubly even number. Ryan loves cooking, working out, and cheering on DC sports teams. Favorite joke? “19 and 20 got into an argument… 21!”

Christina Quach

Instructor

Hey everyone! I'm Christina, a Junior concurrently enrolled in Wheaton High School and Thomas Edison High School of Technology. At Edison, I'm pursuing CompTIA A+ and Network+ certifications this year, with plans to obtain Security+ next year, as part of the Network Operations/Cybersecurity Sector. My favorite number is 28 – it's fun to write in one continuous stroke, especially the looped "2." Interestingly, despite being almost 85% Vietnamese, I speak very little of the language, including my own last name. (Don't ask me how to pronounce it because I'll butcher it worse than you!) However, I am fluent in Cantonese and have basic Mandarin skills.

Sonia Husain

Instructor
Hi everyone I’m Sonia. I’m a senior at the p-Arms School and I will be at Dartmouth next year pursuing an Economics degree! My favorite number is 7 because I was born on the 7th day of the 7th month of the 7th year! In my free time, I like to read, bake, and ride horses.

Kareef Ullah

Instructor
Hi I’m Kareef, a recent graduate from Johns Hopkins University with a Master’s/Bachelor’s degree in Biomedical Engineering and a minor in Applied Math and Statistics. My favorite number is 15, inspired by the jersey number of my favorite NBA player, Kemba Walker. A fun fact about me is that I was a professional cup stacker and am currently ranked 16th in the U.S.! Outside of teaching math, I enjoy stacking cups and playing basketball.

Valerie Song

Instructor

Hello! My name is Valerie. I am a senior at Montgomery Blair High School, and I plan on studying mathematics and computer science in college. I like playing recreational volleyball with my friends, practicing violin (and some guitar), and working on interesting math problems in my free time! My favorite number is 1001 because it’s the same number written backwards and can be written as the product of three consecutive primes. Fun fact: I can perform a little magic with cards - come see it firsthand!
