When a loved one is diagnosed with memory loss or dementia, it is not uncommon for their lives and the lives of family, friends and community to be turned upside down and unravel. My great passion is to assist families in understanding the condition, educating them and assisting in creating a safe and protective environment for the patient, without stealing their independence and abilities. I thrive on assisting families navigate the intricacies of the condition, strengthen their relationships and create a peaceful loving environment for all.
