100 Women Who Care was started in November of 2006 by Karen Dunigan of Jackson, Michigan, as a brilliantly simple way to raise money efficiently and quickly for local charities. Her group of 100 women, at their first one-hour meeting, each wrote a check for $100 directly to the charity, raising over $10,000 to buy 300 new baby cribs for an organization in their city.  There are now over 250 Women Who Care chapters across North America. 

100 Women Who Care Cranberry Township was started in September 2016 by Heather Clark.  She attended a meeting with the Pittsburgh chapter, and saw both the power of collective giving, and the positive impact their group has made.  She knew she could gather a similar group of caring women to do equally important work in the Butler and Beaver County communities.
