Customer Relations Advocate

Sarah Grasso, Administrative Support Specialist

Sarah has been working with children and families in education centers for the past six years. She believes strong relationships with families create a positive experience for all. Sarah is a mom of two who enjoys traveling, cooking, and spending time outdoors.

Anthony Piraino, Education Director

Anthony holds a Bachelors in Mathematics from Boston College. He honed his skills as a private tutor before he joined Mathnasium. Math has always been a favorite discipline for Anthony, though he believes in a holistic approach to education in general. A passionate educator, he strives to create an environment in which students feel comfortable sharing their thoughts and concerns. He believes that dialogue and curiosity are the most important factors in learning.


Customer Relations Advocate

Dylan Cook, Center Director

Dylan has a B.A. in Mathematics and Statistics from Boston University. Before joining Mathnasium, he spent time as a cello instructor for young students. Dylan's favorite part of teaching math is the challenge of explaining a concept in a way that makes sense, and the reward of then seeing students learn and improve. He is always excited to see students make progress and display more confidence in their skills. 


Owner/General ManagerMyrtha Chang, Owner/General Manager

Myrtha has a Bachelor's degree in Computer Engineering from the University of Texas at Austin and a Master's degree in Information technology from M.I.T.  After a rewarding career in consulting for Oracle Corporation, Myrtha launched the first Mathnasium Center in Massachusetts. As a Newton parent, she understands first-hand the high value families in the community put on education, especially in the area of Math, which will drive the majority of our children's careers. Myrtha grew up in Singapore and went through the Singapore Math curriculum. Before Mathnasium, Myrtha would resort to draconian methods such as making her daughter memorize the times tables along with a metronome before letting her eat. That was then. Today, one of the biggest difference about Mathnasium that Myrtha is proudest of is that kids like coming here. Because at Mathnasium, math makes sense, and the learning center environment is casual and fun.

Chief Instructional OfficerLarry Martinek, Chief Instructional Officer  (Headquarters)

Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curricula, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting student's ability to "do" math, thereby increasing student's math scores and feeling of self-worth. Larry is the developer of Mathnasium's educational program - one of the most comprehensive and innovative curricula ever produced for teaching math.
