SIGMA is a non-profit, women’s organization that was founded in 1931. Comprised of 30 local women, SIGMA donates thousands of dollars each year to local charities and families in need. Holiday House, SIGMA’s only fundraising event, is where the organization generates these funds to give back to the community. Last year in 2015, Sigma raised and returned $25,050 to the community, benefitting 28 Fond du Lac organizations. This contribution couldn’t be made without our wonderful vendors and attendees who make Holiday House a success each and every year.
