Wallace has been a portrait photographer and storyteller for 20 years. He will share the story of his book and traveling exhibit, “Portraits of Dementia,” created to destigmatize those living with dementia. Everybody who wants to learn more about this terrible disease and how to understand, appreciate and support those living with dementia is invited to attend.
