Who is Ms. Rachel?

Before having children of her own, Ms. Rachel worked as a teacher. When her son, Thomas, was diagnosed with a speech delay, she searched for videos online that may help him but couldn't find many. Accurso was motivated to create her own videos to help her son, but also other children as well.

Accurso put her dual master's degrees to use (early childhood development and music education) and started creating content that sought to encourage speech development.

Since 2019, Ms. Rachel has grown her audience to 8.66 million on YouTube, 3.9 million followers on TikTok and 1.8 million on Instagram.
