Our Mathnasium Leadership Team:

Jonathan Hamel

After graduating from St. Albans School, Jonathan earned his BA in Economics at Wake Forest University and his International MBA in a joint degree program between the University of South Carolina and the Wirtschaftuniversität Wien in Austria. With a background in economics and a career in finance spanning nearly 20 years, he knows the importance of building a strong foundation in math. As a runner and former lacrosse player, Jonathan was quickly drawn to the idea of developing math skills in much the same way that athletes train to perfect their physical abilities. Jonathan enjoys working with children and is currently a volunteer coach for his sons' lacrosse team.

Laura Hamel

Laura is excited to welcome children and parents to Mathnasium and help kids learn math in a way that makes sense to them! Currently raising three sons, Laura understands the high value families in our community place on education. Laura graduated from Wake Forest University with a BS in Business. After discovering Mathnasium and opening their first center in 2014, Laura and Jonathan knew they had found the perfect way to combine their passion for children and education.

Since moving back to DC Jacob has spent the past three years running after-school programs at a variety of schools within the district. This work mainly focused on providing English and math tutoring to underserved communities in DC with the goal of helping those students get into top area high schools. Jacob is excited to continue working with kids in the district and hopes to continue to put the kids he serves in a position to be successful both inside and outside of the classroom.
