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.

Jenny Colletti

Jenny has always had a passion for teaching. She believes there is more than one way to solve every problem, and loves helping children develop their own sense of problem-solving and critical thinking. She graduated from the University of Miami, where she majored in Math and Sociology and has been part of the Mathnasium team since 2013. She enjoys seeing the difference she makes in children's lives every day at Mathnasium.

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.

Samantha Impellizeri

Samantha is excited to join the Mathnasium team and help math make sense for Miami students! She attended Hofstra University and graduated with a Bachelor's Degree in Speech Pathology, Audiology, and Childhood Disabilities Studies. She has worked with children in various enrichment programs for over 13 years. Samantha has a passion for math that began when she was a Mathnasium student herself back in high school!

Karla Tavarez

Karla has always loved math! She earned degrees in Applied Mathematics and Economics from the University of South Florida and is passionate about encouraging students to share her enthusiasm for math. She is excited to continue to grow with Mathnasium and help create lifelong problem solvers!

Jacob Estes

Jacob is thrilled to be taking over as the Director for the Cathedral Heights center. Jacob first started working with students during his time as a member of the Interactive Theater Troupe during his time at the University of Missouri. 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.

Destiny Chapman

Destiny is excited to join the Mathnasium team in spreading a love for math to students! She earned her Bachelor's Degree in Early Childhood Education at Dallas Baptist Univerity and a Master's Degree in Education Policy from the University of Pennsylvania. Destiny taught middle school math in Texas as well as online students all over the globe as an online instructor for John Hopkins' Center for Talented Youth. She is excited about the opportunity to help students enjoy math through their time at the center!

Gloriya Lasa

Gloriya is an educator, a mathematician, and a life-long learner. Born and raised in Bulgaria, she could not have imagined where life would lead her. Shortly after moving to the United States, she earned degrees in both International Relations and Political Science - as well as a minor in Mathematics - from Florida International University. After earning a Master's in both Curriculum and Instruction, Gloriya grew as both a classroom teacher and a developer of programs and curricula. Here at Mathnasium, she found a home where she pursues her passion for education by facilitating her students' learning and growth.

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.
