My name is Maggie Miller, I have one year of experience as an RBT, but am new to the SpectrumCare team as of August 2022. I fell in love with ABA because I have seen how it can change lives. Helping a child grow through all the changes life may bring is one of the best feelings you can have. When I’m not working with our sweet kiddos, I am coaching Middle School girl’s basketball. I’m so excited to work with such an amazing team and have the opportunity to help change lives!

My Name is Jordan Stone. I have been an RBT at SpectrumCare since May of 2022. I have also been a one-on-one at Vern Riffe School since then. I love working with my one-on-one. It gives me a sense of accomplishment when I watch his growth in accomplishing his goals and improving his skills. I have just started at SpectrumCare and I can't wait to begin working with everyone. I'm excited to be able to work with the kids and watch their progress and grow. I have always loved talking and being around kids that are on the spectrum. They amaze me with how they see the world and each other. They bring so much laughter and silliness that we sometimes need to be reminded how beautiful the world and everyone who live on it truly are.

Hello I’m Sarah Ginn! I am a mom of a toddler with ASD and beginning my own journey of becoming a RBT with SpectrumCare. I look forward to working with the kids and families to achieve their goals and hopefully one day their dreams!

SpectrumCare's Operations Manager is Tanya Benbow. She has been with us since 2018. She is the voice of our office as the intake coordinator and handles getting new clients into our services. Tanya worked as an RBT for a year prior to taking on the administrative roles at SpectrumCare. She has worked in many office roles in many industries over the years but says this about us, "The services our team provides to our community are meaningful and it feeds my soul to be part of such an impactful team. Making a lifelong positive influence in any individual’s life has always made my heart full. I am grateful to have the opportunity to work in a field that truly makes a difference to the community it serves. The people you will encounter on our team are by far and large some of the best humans I know."

Hello! I’m Bradie Chapman and I have been at Spectrum Care since July of 2020. I have found this position to be so rewarding in many ways. I love helping the kids to learn skills that will help them throughout their lives and seeing how appreciative the parents and family members are to see the growth in their child. I enjoy working with the kids and seeing that “aha moment” when a trial that we have been working on for a while comes to them and then they surge forward another step in their journey.

I have a Master’s in Education and taught in the university setting for 13 years before coming to Spectrum Care. I am also a Certified Therapeutic Riding Instructor through the Professional Association of Therapeutic Horsemanship (PATH, Intl.) and have been active in the field since 2003. I have taught many participants both in and out of the saddle about horses and how they can have an effect on their lives, physically, mentally, and emotionally. I have enjoyed working with children and adults with various therapeutic needs.
