The Walk to End Alzheimer's is an inspiring event that connects strangers together through stories and experiences of being touched by Alzheimer's disease for a mission to find a cure and End Alz! The Purple Knights have Walked to End Alzheimer's in memory and honor of Raymond Knight Tussing for the last 13 years. We walk in the hope that one day there will be an end to Alzheimer's disease. We will never be able to say thank you enough to the family and friends who have supported our team over the years.
