Brain Balance Center of Mequon – Meet Our Staff


Our Team

Lynn and Jason 2021

Lynn & Jason Brittnacher

Owners/Executive Directors

The past five years of Lynn and Jason’s family’s life were filled with health challenges that seemed insurmountable. Leaning on God through these times allowed them to come out on the other side, stronger and more blessed than they could have ever imagined. With grateful hearts, they turned their eyes upward and asked, “What is your plan for us God? We are here to serve.” God answered them with an overwhelming need to use their talents to help individuals who struggle.

Lynn is the Executive Director of Brain Balance of Mequon; she has her degree in Elementary/Middle School Education with minors in Adaptive Education and Social Studies from the University of Wisconsin Platteville. She also received her masters in School Counseling from Lakeland University. Her passion has always been working with children and supporting those who struggled with ASD, ADHD, EBD and Learning Disorders. After 17 years of teaching Lynn started looking for something that would get to the root of the problem, giving children the underlying skills they needed to be successful in all areas of life. After researching and learning about Brain Balance she knew it was the path she must take. Jason has always loved working with children, he completed his certification as a Board Certified Cognitive Coach and has taken on the Lead Coach role, he loves helping children reach their highest potential.

Together, they jumped in with both feet, as they knew it was the direction they needed to go. They have found immeasurable joy in helping kids make profound change and watching families’ lives transform. The mission of this center is to help as many children as possible grow to their God given potential.

Emily Wollner

Center Director

Emily Wollner is the Center Director. She has her Bachelor's Degree in Early Childhood Educational Studies and in Adaptive Education from Concordia University in Mequon. She is also a Board Certified Cognitive Specialist through IBCCES. Throughout Emily’s time in high school and college she worked at daycares, children's centers, and adult group homes. After graduating college, she continued her work with the special needs population doing ABA Therapy and then eventually continued on to use her knowledge in early childhood as a preschool teacher. Brain Balance immediately caught her attention when she found herself wanting to do even more and somehow "combine" everything she had learned into one career. That's exactly what Brain Balance is. Every job leading up to Brain Balance was important to Emily, including the students and the families, but Brain Balance has truly been her calling. Getting to work with kids and families and change their lives has been the biggest blessing and the reason Emily loves her work at Brain Balance so much.
