Team Member Bio

I’m Catherine Callahan, M.S., CCC-SLP, and I joined Monkey Mouths in 2020, and I am the Southlake Annex Assistant Clinical Director. I earned my undergraduate and master’s degrees from Baylor University. Prior to Monkey Mouths I worked in private practice and school settings.

I believe in creating a fun and natural environment for children to learn in. I strive to make my sessions engaging and purposeful for both the child and the parent.

In my free time, I enjoy traveling, cheering on the Baylor Bears, and spending time with my husband, Chris, and my dog, Scooby.

  • Sound Card System
  • PROMPT therapy
