Meet the Team
Erin Wilke OTR/L
Founder of Treehouse Therapy
Erin started Treehouse Therapy in 2019 when she felt a calling to support children and families and their struggles at home in addition to the work she was doing in the schools. Erin has been an OT for over 20 years and has loved working with children her entire career. Erin has worked in outpatient therapy clinics, in homes and in the schools, so she brings extensive experience from each of those settings into her practice. Erin loves working with families to try to alleviate the daily stressors that their children are having. Erin especially loves working with children outdoors, as she has seen first hand the amazing impact nature can have to make children feel more calm, confident and connected. Erin has extensive training in sensory integration (SIPT certified), DIRFloortime, SOS Approach to Feeding, the CONTIGO Approach (for outdoor OT), Powerfully You (for social-emotional regulation), Handwriting Without Tears, and always brings a neuro-affirming approach to her work with children and families.
Erin lives in Signal Mountain near Chattanooga, TN with her husband and 3 children, plus a couple of furry pets. Erin loves spending time with her family and friends, traveling, hiking, gardening, weight training, running, and being outside as much as possible.

She is a certified Dynamic Movement Intervention (DMI) practitioner (Introductory Level A), has experience with MNRI reflex integration, and is currently participating in the EDS ECHO program for allied health professionals, which focuses on care for patients with Hypermobility Spectrum Disorders (HSD) and Ehlers-Danlos Syndrome (EDS).
