SPEECH LANGUAGE PATHOLOGIST

Essie Jennings, M.A., CCC-SLP

I decided to address you directly as a first time mother. I feel this is my most sacred title: mom. My first name is Essie (sounds  like the letters "S" and "E" blended together "SE") but originally my mom named me "Lesley", but my older cousin did not have her "L" sounds in yet and called me "ssseee" and the name stayed. I love helping children and adults talk. When I was little, I talked to trees the most on the playground in Kindergarten. My mom was concerned, but my teacher helped me. I feel that I am called to help others communicate. Whether that be with using their hands (signing), singing, pointing, or just through their facial expression, I want to help them share their thoughts. I started in hospital setting, now I love providing communication intervention across modalities and environments. whether directly at the Wala'au house or your home, let's continue to connect and potentially across the globe.
