Our tutors foster a caring, encouraging environment that helps kids thrive and learn! Read below to learn more about our talented team:


Larry Martinek, Chief Instructional Officer   

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 an educational consultant. He has designed curriculum, teaching strategies, and teaching materials to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students’ ability to “do” math, thereby increasing students’ math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program, one of the most comprehensive and innovative curriculums ever produced for teaching math.

While Larry is not an Instructor at our Center, he is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students. 


Alan Saxena, Center Owner

Inspiring the next generation of minds is the most important undertaking of all.

Alan is the owner of Mathnasium of Avon, as well as another center in Trumbull CT and Manchester, New Hampshire. When Alan first heard of Mathnasium so long ago, he never could have dreamed of how many lives he would change for the better. Now, almost 5 years after deciding to start a center of his own, he wouldn't change a second of it! With all of the hustle and bustle of running 3 centers, Alan is generally a motion blur, always moving and never sitting still. He is always happy to make time for our parents, however, and loves to chat about how their students are doing wherever life takes them!


Andrew Fisher, Regional Director

On a mission to take the 'fear' out of math

As the Regional Center Director my job is to make sure every student loves their math experience here and develops solid math confidence.  I have been a math enthusiast all my student years and have found the Mathnasium method to be the best method of teaching math. I was a calculus student in high school ( A grade) and a Math major in college and I believe every child has the potential to excel at math if they are taught the concepts in the right way. Their 'aha' moment when they finally get an elusive concept makes my day! I help children arrive at their own understanding of math concepts and learn how to solve for answers rather than memorize answers or 'math facts.' That is the first building block for a lifetime of Math Confidence.  
An avid hiker, I have hiked many Northeast U.S. trails and even tumbled down a mountain once . But I didn't give up -- I still hike every chance I get!


Lisa Parsons, Instructor

Lisa studied math at Clarkson University, where she earned a bachelor’s degree in computer science before earning a master’s degree in social psychology at UNH. She studied under the director of UNH’s Center for Excellence in Teaching and Learning and taught statistics while at UNH. 

Jacob Ross, Instructor 

Jacob is a student favorite math teacher and lacrosse coach at Bow High School. He graduated from Plymouth State in 2010 with a B.S. in Math and in 2016 with a Master's in Educational Leadership. At PSU he received the Geneva Smith scholarship, the Presidential scholarship, and the Outstanding Math Major award. He has presented at New England College's and Lyndon State College’s leadership conferences. Jacob and his wife, Kali, live in Contoocook with their three children. 

Nathan Duplessis, Instructor 

Nathan started instructing at Mathnasium in March 2017, when he was a junior at Manchester Central High School. He is studying mathematics and accounting at Saint Anselm College in Manchester, where he is in the honors program and is part of the Multicultural Student Coalition. He received a New Hampshire Teachers of Mathematics Award and an NHIAA Scholar Athlete Award. Nathan loves sports, especially hockey, and is very good at geography. Try quizzing him sometime. 

Lara Chern, Instructor 

The newest addition to our team of instructors, Lara is a graduate of Bow High School and will be studying mechanical engineering at the University of Maine. She likes physics and calculus, and plays piano and Unified Sports.
