Anne Ernst, Operations and One-on-One Coordinator

Anne joined the Madison Playhouse as a Math Coordinator in January 2022.  She expanded her volunteer role to include Literacy Coordination later that year and was thrilled when the position of Operations/1 on 1 Coordinator opened up Fall of 2023.  Before joining our Playhouse, Anne spent 13 years as a Pediatric Physical Therapist, primarily in Early Intervention but also in Schools and Outpatient Clinics.

After spending several years 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.
