Additionally, Clair has the lived experience of being profoundly deaf herself, as well as having a sight impairment and a mild cerebral palsy.

She is acutely aware of the problems faced by our teens and youth and she is compelled to help others to navigate their path in this challenging world and in all stages of life.
