Darragh has been a leading advocate to find, create and promote more affordable hearing solutions and care systems for the general public. He has been honored by the Mayor and Board of Supervisors for his work, has served on the Western Addition Steering Cohort, is a member of the National Association of Speech and Hearing Centers, and currently serves on the Alumni Committee of Leader Spring and the advisory board of LesserSound.
