Our Team

Our specially trained math instructors will teach your child how to understand math in an individual setting; our unique approach enables us to explain concepts really well and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn! Read below to learn more about our talented team:

All are highly qualified, experienced, and rigorously trained individuals who must first pass a comprehensive set of verbal and written assessments covering all aspects of mathematics and instruction philosophy before even being considered for a position. Background checks are an essential part of the hiring process as is a "trial run" interaction with the students. Finally, all instructors are required to undergo continuous training. Our staff not only does an excellent job of teaching math, but they create a positive, enthusiastic atmosphere providing the support and encouragement your child may need. All of our instructors are passionate about math and love to work with the kids. They are there to help your child succeed in school and in life. 

CenterDirectorAli Noltner, Center Director 

Welcome!  I’m Ali Noltner, the Center Director for Mathnasium of Brookfield. I have a passion and love for teaching and mentoring students.  After learning about the Mathnasium Method from my experience as an instructor, I knew Mathnasium was the perfect home for me.  I work to develop a true partnership among the student, parents, school, and Mathnasium staff to provide the support a student needs to develop and improve math understanding and achievement.  Mathnasium is meaningful to me because students make impressive gains in math, but also improve self-confidence, homework habits, and attitudes toward school.  I graduated from the University of Wisconsin - Stout with a degree in Retail Merchandising. I'm excited to share my love of math and business in this role. But most importantly, I'm looking forward to getting to know all of the families that come through our doors, and the community to continue to grow our center! 


CenterDirectorDerek Pipkorn, Owner

Hi! I'm Derek,  the owner of Mathnasium of Brookfield. I also own Mathnasium of Lake Country, Mathnasium of Mequon, and Mathnasium of Wauwatosa - yes, I love Mathnasium! Prior to becoming a Mathnasium owner, I worked as a Middle School Math Specialist in the Mequon-Thiensville School District. I previously taught elementary and middle school students in Milwaukee Public Schools and the West Allis-West Milwaukee School District. I have a Masters of Educational Leadership from Cardinal Stritch University and a BS in Middle Childhood - Early Adolescence Education with math emphasis from the University of Wisconsin-Milwaukee.

I've been actively involved in math organizations at the State and National level. I was previously the chair of the Classroom Resources Committee for the National Council of Teachers of Mathematics and recently finished a term on the Board of Directors for the Wisconsin Math Council. I have taught and tutored children of all ages, and I am committed to bringing the Mathnasium Method to the children in the community I live in. Married to Jillian, dad to Lucy & Ellie, and dog owner of Willie (corgi), I love staying active in the community and enjoying all that the Greater Milwaukee area has to offer.

In my free time, I enjoy going to Door County with my family, reading or going on a run!

CenterDirectorLarry, Instructor

Hello! I’m Larry and I am a semi-retired WCTC instructor who joined the Mathnasium staff in July 2019. I retired in 2015, but I am still teaching part-time. I graduated from Marquette University, with a degree in Mechanical Engineering and worked in the Milwaukee area in quality control and manufacturing engineering positions. After I joined WCTC, I provided onsite training for employees at many companies, was involved in self-paced, individualized courses on campus, and supported our quality improvement teams. I transferred to the Math department, where I taught a variety of Math courses. While in the Math department, I completed 12 graduate credits in Mathematics at Marquette. I enjoy seeing students gain knowledge and skills in Math and the confidence that comes along with that growth. It is great to see the enthusiasm of the students and staff at Mathnasium. The students are eager to learn as they complete the worksheets in their learning plans. I like to keep a light, relaxed tone and know that humor can add to creating and maintaining a good learning environment. I follow the main professional and college sports, along with news and business trends.I live in Brookfield with my wife Joyce.

I'm David, a Junior at Heritage Christian Schools in New Berlin.  I'm currently working on classes like AP Calculus and AP Biology.  I love to help people learn and grow whether it is in math or at my church in the children's ministry.  Outside of the classroom, I enjoy spending time with my friends, playing video games, and learning new things.  I'm excited to see you and get to know you at the Mathnasium Center! 

CenterDirectorSoumaya, Instructor

Hi! My name is Soumaya, and I am so excited to be an instructor at Mathnasium! I’m an incoming junior at Hamilton High School, and math is, of course, my favorite subject. I love helping people and teaching kids, and I am looking forward to being able to do so as part of this team! I’m a third-degree black-belt in martial arts, and in addition to that, in my free time, I enjoy reading, singing, dancing, and playing piano and violin.

Caroline, Instructor

Hi everyone! My name is Caroline, and I am a freshman at the University of Notre Dame.  What I love most about math is that it is one field of study we use every day. Whether we are counting fingers and toes or making change at the grocery store, we all need math. I am so excited to help Mathnasium students develop their own particular passion for learning and problem-solving! In the future, I would like to attend dental school and become an oral surgeon. For now, I enjoy volunteering at the Ronald McDonald House and interning at a local dentist's office. My favorite hobbies are photography and kayaking on the lake (especially when it's windy!). I am so lucky to be a part of such an amazing team at Mathnasium! 

Jaya, Instructor

Hi! My name is Jaya and I am currently a junior at Brookfield East High School. Learning has always been a passion of mine, and math and science are my favorite subjects. I hope that by tutoring younger kids I can instill this passion in them too! At school, I started a Science National Honor Society to get students involved in STEM related activities. I am also Class Treasurer and I write for my school's publication. In my free time, I love to play tennis, travel, and spend time with my friends and family. I can't wait to see you at Mathnasium!
