August 25th Queen of Hearts Winner

Congratulations to Marengo resident Cyndi W. who was the Queen of Hearts winner on Tuesday, August 25th, 2020. 

Cyndi is a Veteran’s Service Officer who connects Veterans with much needed resources.  She was in the process of finding resources for a local Vietnam era Air Force veteran whose home was uninhabitable due to a flood.  She recently moved him into a hotel in Woodstock so she could have time to pull together the resources to have his home repaired. 

When we called her Tuesday night, the first thing she said was “Now I can pay to help my Veteran get back in his home sooner” 

After helping this veteran restore his home, the winnings will be used to open their barn wedding venue, a dream they have always had.  They will also employ veterans who live at New Horizons and TLS. 

Thank you to all who continues to support the Marengo Union Chamber of Commerce to make this a success and congratulations to Cyndi and her family.
