Anne Ernst, Math Coordinator and Literacy Co-Coordinator

Anne is a Pediatric Physical Therapist and currently stays home with her two children. She spent the majority of her career working in Early Intervention, but also spent some time in Schools and Outpatient Clinics.  Anne became a PT because she has a cousin with Cerebral Palsy.

As a stay at home mom, Anne wanted to get involved in the community again in a more meaningful way. GiGi’s Playhouse was a perfect fit given her background and love of children with different abilities, especially children with Down syndrome.

Anne also volunteers at her children’s school, Hickory Hill Academy, and loves to travel with her family.
