Derek Pipkorn

Owner
Hi! I'm Derek, the Owner of Mathnasium of Lake Country. I also own Mathnasium centers in Brookfield, Mequon, and 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 Bachelors 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 our community. 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.

Jillian Pipkorn

Director of Marketing
Hello! I'm Jillian, the Director of Marketing and Community Outreach for four Mathnasium locations in the greater Milwaukee area that my husband, Derek, and I own -- Brookfield, Lake Country, Mequon, and Wauwatosa. I am thrilled to be a part of our growing Mathnasium team and love the impact that we are making in children's lives and our local communities. I enjoy making connections in the community with schools, kid-centric organizations, and other small businesses. (Let's connect if you fall into one of these groups!) I am a graduate of Indiana University with a degree in Marketing, and prior to joining Mathnasium spent 12 years developing Marketing Strategy at Kohl's. I also have years of experience event planning and fundraising for Susan G. Komen as a volunteer in the fight against breast cancer. When I'm not working on all things Mathnasium, I enjoy spending time with my two daughters Lucy & Ellie and our corgi Willie, being active, trying new recipes from my cookbook collection, and attending musicals.

Our Instruction Staff

Math Instructors (Tutors)
Our staff consists of certified teachers and retirees, high achieving college students, and exceptional high school students. 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 kids. They are here to help your child succeed in school and in life. We welcome you to drop by and meet us anytime!

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
