GMG Jr./Sr. High School


Dear Friends of GMG:

 We, as a community, have an obligation to provide a safe and wholesome atmosphere for our children and young adults. Our students mean a lot to us and we truly want to keep each and every one of them safe. After-Prom is an alcohol and drug-free event open to all GMG High School Juniors & Seniors, whether they attend Prom or not, and is organized by parent volunteers.

GMG High School will hold its annual After Prom on Saturday April 21, 2018 at the Marshalltown YMCA.  We have food and a large array of activities for our kids to enjoy -Bubble Soccer, Laser Tag, Swimming & a Hypnotist, just to name a few.   

To provide the best event that we can and entice our students to attend, we need approximately $6,000 to offset our expenses. We are asking YOU to consider donating monetarily.  No donation is too small. 

We thank you for your dedication and generosity to GMG and greatly appreciate your help towards attaining our goal of a safe and entertaining environment for our children.

Please make checks payable to GMG After-Prom & mail to:
