Two people who have been fixtures in efforts to promote healthy life habits and education for children and families in Hood River County are retiring at the end of June.  Hood River County Prevention Department Director Joella Dethman and Prevention Specialist Maija Yasui both say while they are leaving their paid jobs, they both plan to remain involved in efforts to help children.  Dethman says one of the big changes she has noted over the years is the ability to better track the outcomes of their efforts.  The County is in the process of finding a successor to Dethman.  The Hood River County Prevention Department was known as the County Commission on Children and Families until a reorganization of the state’s youth services structure two years ago.
