Dr. Carolyn Cassill
Hi, I'm Dr. Cassill!
I work with children, teenagers, and young adults with various neurodevelopmental concerns including autism, ADHD, intellectual disability, and learning difficulties. One of my key interests is early identification of autism and developmental weaknesses in young children, as I know that early identification and intervention lead to improved outcomes.
My training at top institutions in Texas and Massachusetts has given me extensive understanding of neurodevelopment in children ages 1-22, including those with complex medical backgrounds. I can provide recommendations and resources for navigating services both in school (Early Intervention, 504 plans, IEPs) and outside of school (home and community-based therapies and interventions).
In my free time, I enjoy trying new food, playing video games, traveling with my husband, playing and cuddling with my two cats, and maintaining a patio garden.
