Jim Aloisio ~ Owner / Master Instructor

Hi, my name is Jim Aloisio and I am the owner of Mathnasium of North Beverly. My wife Mary and I have been married for over 30 years and we have three great kids who are now grown, out of college and living on their own. When they were growing up, Mary and I were very active and involved in their education and extracurricular activities. Mary was an officer of our local PTA for many years and I coached soccer and baseball. Being involved in the community has always been an important part of our lives.

Over my years as a professional, I have had many diverse experiences from business owner and executive manager, to math teacher and head of the Gloucester High School math department. In 1997 I volunteered my time designing systems to evaluate MCAS data for the City of Gloucester. During this time I developed a strong bond with several teachers and administrators and began to consider teaching. In 1998, I made the leap from businessman to math teacher in the Gloucester public schools. It was one of the best decisions of my life. For ten years, I taught math first in the middle school and high school levels, ultimately becoming Department Head for the High School Mathematics Department. During this time I taught every course the department offered. It was a fantastic experience that brought out my passion for teaching and helping young minds grow. This led to my decision to open a Mathnasium center.

As the owner of the Mathnasium facility in North Beverly, I utilize my passion for teaching math and for helping young people, and helping other math teachers to do the same. The creator of Mathnasium's curriculum, Larry Martinek, is an insightful math instructor who has "broken the code" for teaching math in a simple way that makes sense to everyone. As Larry often says, "Showing a student that they can succeed in math can change the course of his/her life". Through Mathnasium, I have learned many approaches and techniques for tailoring lessons to a particular student's way of thinking. The underlying math is the same, but how it is presented is terrific in its simplicity and elegance.

Mathnasium of North Beverly is a bright, open and fun location where students of all ages come to catch up, keep up, or get ahead in math.  We even offer test prep for the SAT, PSAT, ACT and high school or private school placement exams.  Prize cabinets, raffles, game nights, student rewards, the Annual TriMathlon, and other events--in addition to an excellent teaching staff that specialize in math--make our center a place kids love to come to.  We hope you will visit our center or contact us to discusss our programs.  -Jim

Sarah Yoon ~ Center Director / Instructor

Sarah earned her BS in Mathematics (Actuarial Science concentration) with a secondary major in Marketing from Umass Amherst in December 2016. Although the primary focus of her studies has been Mathematics and Marketing, she has cultivated additional experience in multiple programming languages as well as extensive coursework in areas such as management and finance. She has also volunteered at Boston Children’s Hospital and Cary Memorial Library, and worked as a Marketing Intern at Auburn University at Montgomery this past summer. Her enthusiasm for mathematics extends outside of her education, manifested in her desire and passion for teaching. Tutoring children has been an integral part of her life since middle school, extending over a broad range of subjects ranging from Algebra to the ACT. She understands how intimidating math can seem, and how one size does not fit all when learning.

Aliana Robichaud ~ Assistant Director / Instructor

Aliana graduated from University of Connecticut with a degree in Math and Statistics, with a focus on financial math. In addition to her math related coursework, Aliana enjoys learning about different cultures and languages, including ASL! In her spare time she coaches the UConn Colorguard and volunteers at middle and high schools throughout the state of Connecticut working with the music programs.



Ian Murphy ~ Lead Instructor

Ian is a former statistics, composition, and computer science tutor turned Mathnasium Instructor working for a computer science degree. For Ian, teaching is as fun as you make it, and bringing math into real (or even fictional) examples is instrumental for play and education alike: preferably, for both.




Additional Instructors:
