Join FLX Healthy Hearts founder Samantha Page the week of Fathers Day to enjoy healthy fun with your dad, celebrate a survivor, or honor a loved one that lost their life to a heart attack or stroke. Samantha is a 16-year-old Waterloo High School Junior who formed FLX Healthy Hearts after her father suffered a major and debilitating stroke. All proceeds benefit the American Heart Association and their efforts to raise awareness about prevention and educate people about heart attacks and strokes. Event Web page.
