 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 as an educational consultant. He has designed curriculum, 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 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 advise. This has helped to make visits more productive and enjoyable for many of our students. 

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 and 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 US trails and have even tumbled down a mountain once . But I didnt give up - I still hike every chance I get!

Dylan Shubelka, Assistant Director

Thanks to his powerful math and engineering background, Dylan joined Mathnasium in 2015 and quickly impressed the staff and students with his mental math skill and an ability to make math easy to understand and learn. Dylan's background is in aeronautical engineering and while at Mathnasium he also helps to maintain and enhance the quality of our curriculum and instruction. 

Lisa Parsons, Associate Director of Education

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. As our Lead Instructor, Lisa uses her eye for detail to effectively manage and oversee the instructional floor, ensuring that our talented instructors are able to focus on each student.

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. 

Lauren Goyette, Instructor 

Lauren is a senior at Bow High School, where she is a standout three-sport athlete (soccer, basketball, and tennis). She is currently taking multivariable calculus. Lauren came to Mathnasium to learn how to instruct and tutor students in math so that she could apply her skills as a peer tutor for the National Honor Society, of which she is a member. Lauren mastered the Mathnasium teaching method in record time and is a student favorite thanks to her skill and encouraging personality. 

Nathan Duplessis, Instructor 

Nathan started instructing at Mathnasium in March 2017, when he was a junior at Manchester Central High School.
