Hook Rehabilitation staff
I have been involved in the fields of aging and disability since 1983. The main emphases have been developmental disabilities, traumatic brain injury and aging. I graduated from Wabash College in 1983 with a B.A. in Psychology. I received an M.S. in Psychology with an emphasis in rehabilitation from Purdue University in 1992. I am also licensed as a health facilities administrator in Indiana.
An area of special interest over the last several years has been systems change. Through my work with the state, I became very familiar with CICOA and its mission, and am currently on the Board of Directors for CICOA. I worked closely with the advocacy and provider communities to drive changes into Indiana’s systems, and became involved with the basic needs committee of the AdvantAge Initiative. I have maintained that interest and those working relationships. I currently serve on the Boards of Directors of both the Brain Injury Association of Indiana and the Indiana Association of Homes and Services for the Aging. These agencies have many common interests with CICOA, and it appears the work can be complementary. I also serve as a member on the Mayor's Advisory Council, which emphasizes inclusion and awareness of persons with disability in Indianapolis.
