With more than eight years of experience working with children on the autism spectrum, Randeigh is passionate about helping kids build skills and reach their potential. She has worked one-on-one with children, developed personalized plans to support their growth, and partnered with families to find strategies that work for them. Starting as a behavior technician and growing into her current role, Randeigh takes pride in creating positive, nurturing environments where children can thrive and families feel empowered. Seeing the progress children make, whether it’s learning a new skill or gaining confidence, is what drives her every day. She looks forward to continuing to make a meaningful difference in the lives of the children and families she serves.

“The best days are when a child meets their goals and graduates from our services. Compassionate and contemporary ABA therapy can make a tremendous difference in the lives of children and their families, and I feel fortunate to have a small part in that.”
