Our Team

Lynn Brittnacher

Owner & Executive Director

With over 25 years of experience working with children facing social, emotional, behavioral, sensory, and developmental challenges, Lynn Brittnacher, M.A., BCCS,  is deeply committed to helping children and families navigate the complexities of developmental difficulties. Giving God the glory for the opportunity to serve others, Lynn’s work is driven by a deep faith and passion for making a lasting, positive impact. As a dual-licensed educator in Elementary/Middle School and Adaptive Education, along with a Master’s Degree in Counseling from Lakeland University.  As a Board-Certified Cognitive Specialist (BCCS), Lynn is dedicated to providing families with the tools, strategies, and support they need to help their children achieve their fullest potential. Lynn brings a unique blend of expertise in education, counseling, and child development.

For seventeen years, Lynn served as a 7th grade Reading and Language teacher, where she worked tirelessly to support students who struggled academically and emotionally. It was during this time that she realized traditional methods often focused on managing symptoms rather than addressing the root causes of children's challenges. This realization led her to seek a more holistic approach to supporting children, one that focused on understanding and addressing the neurological and developmental factors that impact a child’s success.

Lynn along with her husband Jason are the proud owners of two Brain Balance centers: Brain Balance of Fox Valley and Brain Balance of Mequon, and are excited to be opening a third location, Brain Balance of Madison, in 2025.  Lynn is dedicated to providing families with the tools, strategies, and support they need to help their children achieve their God given potential.

Outside of work, Jason’s life revolves around his faith and family, which are his greatest sources of inspiration. Alongside his wife, Lynn, and his five kids, he also enjoys spending time in nature and engaging in hands-on hobbies like gardening, fishing, hunting, and woodworking. These passions reflect his love for creating, nurturing, and connecting with the world around him.

Dedicated and driven by purpose, Jason thrives on making a positive impact in the lives of children and families while staying grounded in the values that guide his journey.

Elizabeth Reardon

Program Director

Hi! My name is Elizabeth Reardon and I am one of the Program Directors at the Brain Balance Center of Mequon. I have a master’s degree in Occupational Therapy from Concordia University Wisconsin and a Bachelor’s of Science degree in Psychology from the University of St. Thomas. While in graduate school, I worked as an ABA therapist with neuro-divergent children ranging from 2-7 years of age by helping them learn new skills. Before discovering Brain Balance, I worked in a pediatric out-patient clinic and worked with children with a variety of conditions including autism, ADHD, sensory processing disorder, ODD, anxiety, etc. I created and implemented individualized treatment plans to help children increase independence in daily activities and improve quality of life. 

Brain Balance initially caught my eye with their emphasis on using a holistic, non-medical approach to re-creating brain development, especially with having a background in Occupational Therapy. I love working directly with families to create an individualized plan to mature brain connectivity and neural pathways. It is so fulfilling and rewarding to me to see functional changes in areas of concern by improving emotional regulation, focus and attention, academics, social skills while minimizing behaviors. My passion is helping children reach their fullest potential and giving them the tools they need to be set up for success. My goal is to have children go out in the world with confidence and be who they are meant to be and I feel endlessly blessed that Brain Balance gives children and families the opportunity to do so.
