Her goal is to enhance and elevate the lives of people with diverse needs, to provide information to them, their families and the community, and to advocate on behalf of those she serves.

Her passion for helping those with special needs has filled every facet of her life.  She currently serves on the Board of Directors at the Munroe-Meyer Institute at the University of Nebraska Medical Center as President, the Brain Injury Alliance of Nebraska, The Down Syndrome Alliance of the Midlands and the Education Rights Counsel.
