When my husband and I started our journey as the parents of a child with disabilities we were so lost and isolated. It wasn’t until we started meeting other parents who had similar experiences that we started to feel a sense of belonging and acceptance. My goal as the Family Support Coordinator is to make sure that all of the parents, caregivers and family members of those with disabilities or unique needs also find a welcoming community where they feel like they belong.”
