One of the most meaningful parts of Rotary's Big Monster Mash is putting some of the giving power directly into the hands of our guests!

Throughout the evening, you'll have the opportunity to learn more about five incredible local nonprofit organizations and the work they're doing in our community:

🐾 Humane Society for Greater Nashua

🐕‍🦺 Operation Delta Dog

Then it's up to YOU!

Every guest will have the opportunity to cast their vote for the Featured Nonprofit(s) they would most like to see receive Souhegan Valley Rotary's $2,500 Community Choice Donation.

Come meet their representatives, learn about their missions, discover the impact they're making throughout our community—and cast your vote for the organization you'd like to support!

This is more than just a Halloween party. It's a night to connect with friends, support local businesses, celebrate our community, discover some incredible local organizations, and make a real impact—all while having a ridiculously fun Halloween night out!

✨ Costumes are highly encouraged (but not required!), so come dressed to impress for a chance to take home one of our costume contest prizes.

And there's plenty more to come! We'll be highlighting each of our Featured Nonprofit Partners, recognizing our amazing sponsors, revealing raffle prizes, sharing entertainment updates, and announcing more surprises as we get closer to the big night.
