Mary Pat Daly, SLP


Mary Pat Daly is a speech-language pathologist on the BIRC team. She is an Iowa native who completed her Master's of Science Degree in Speech-Language Pathology from the University of Washington in Seattle. Throughout her career, Mary has always specialized in brain injury rehab and has worked in almost all levels of the treatment continuum.

Mary recently shared her thoughts on the BIRC treatment process.  “If you think about the different communication exchanges you have in any one day and where those occur, it only makes sense that speech-language therapy has to move beyond the treatment room. When a person's communication skills are altered due to stroke or acquired brain injury, the treatment process initially requires an intensive amount of practice and repetition.  Sooner, rather than later, it's time to apply those skills with a variety of people and in multiple settings.  And that's the real strength of our program. Clients have opportunities to practice their skills with each other in our groups. For example, they may give a presentation, visit stores or ride MAX (light rail), all in an attempt to hone their communication skills. Later on, we may visit the volunteer site or work setting. Clients gain confidence and blossom during their time with us.”
