Our Team

Rhonda Zollner

Center Director

Rhonda Zollner is the Center Director and owner of Brain Balance Plainfield.  It’s been her pleasure, since October 2011, to work for Brain Balance Achievement Centers.  Her degree is from Marian University in Elementary Education.  Over the years, she has taught a variety of grades and experienced working with children of various backgrounds. However, she became frustrated with the uncertainty some children faced regarding diagnosis and treatment of developmental delays like Dyslexia, ADHD, Autism and processing.  Brain Balance Achievement Centers was the answer she was looking for.  It’s her passion to educate parents and teachers on other options besides medication and tutoring. Her son went through the program, three years ago, and had such phenomenal results, she decided to open a center in her community. She looks forward to helping more families in her local and surrounding communities.
