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.

Henry Fowler

Lead Instructor

Henry previously taught 5th and 6th grade math at Immaculate Heart of Mary before fully committing to his role at Mathnasium. Passionate about creating a supportive learning environment, he enjoys helping students build confidence and a strong foundation in math. His goal is to make math both accessible and enjoyable for every student.

Outside of teaching, Henry is a big baseball fan and loves watching Star Wars movies and TV shows. Whether in the classroom or at Mathnasium, he is dedicated to helping students succeed in their math journey.

Beverly Lewis

Lead Instructor

Beverly taught algebra, pre-algebra, and general mathematics for grades 6-8 in the Southeast Delco School District. She holds a Bachelor of Science in Mathematics from Millersville University and a Master of Education from Widener University. 

After retiring from public education, she missed teaching and student interaction. At Mathnasium, she found both—along with an excellent curriculum that helps students truly understand math. She loves being part of a learning environment where students can thrive. 

Peggie Weader

Instructor

Peggie recently retired after 27 years of teaching math, both in the U.S. and West Africa, where she even learned French to teach abroad. She holds a Mathematics degree from Hartwick College and two master’s degrees in Secondary Math Education and Applied Educational Technology. 

She believes the most important part of teaching math is helping students overcome the idea that they "can't do math"—because they absolutely can! Peggie is excited to continue inspiring students at Mathnasium. 

Dan Dougherty

Instructor

Dan’s love for math began during his mechanical engineering studies at Deltech, where he later taught and tutored math. After five years in education, he transitioned to construction but always hoped to return to teaching. In 2023, he joined Mathnasium, reigniting his passion for math and education. 

When he’s not teaching, Dan enjoys playing board games with friends and participating in his lodge as an Oddfellow. He is excited to help students develop their math skills and confidence at Mathnasium. 

Seemy Hodge

Nollan Fayehun

Instructor

When he’s not building robots or competing in Science Olympiad, you can find him tutoring math, leading the Math Honors Society and Robotics Club, or playing saxophone with the marching band. Nollan loves solving problems, working with others, and sharing what he knows with those around him. He brings curiosity, creativity, and plenty of enthusiasm to everything he takes on.
