Mission & Vision
Mighty Oak ABA offers Applied Behavior Analysis services to children with autism or related developmental disabilities in and around Portland, OR. Contact us if you have any questions or would like to learn more about Mighty Oak and how we can help your child reach their fullest potential.
Mighty Oak ABA strives to help foster an empowered autistic community by nurturing development through access to highly informed, empathetic, and ethical ABA services. We aim to provide a consistent and dependable service that families can rely on.
Historically marginalized communities deserve equal access to opportunities for empowerment on a basis of empathy. The autistic and neurodivergent communities have unique skills, talents, and perspectives that should be included and accepted into what is considered the status quo or mainstream. There should be room and resources for those who need it. This is about humanity and human rights for all through recognition of adversity and an effort to bridge that gap.
