We support our troops!  These men and women gave more and deserve our support. While we don't need more reasons than that, my husband, son, daughter, and many other families have served our country through military service and this is my way of giving back to all of our troops.

Special Olympics of Oregon


Why do I support Special Olympics? My sister has a severely disabled child and while she is so disabled that she cannot participate in the Special Olympic events, my sister and her family support Special Olympics and so do I.    

Why do I support the South County Food Bank? Many years ago, my family received food from the South County Food Bank. Those special gifts of food meant so much to my children and I for nutrition, for feeling part of the community and not forgotten. Now I am able to give back and support the food bank with donations of food and money.
