Rotary's Big Monster Mash!

A Halloween Party with a Purpose!

Join the Souhegan Valley Happy Hour Rotary Club for Rotary's Big Monster Mash—an unforgettable evening of Halloween fun, community connection, and giving back!

Whether you're coming with friends, family, coworkers, or flying solo, you'll enjoy an exciting night filled with entertainment, laughter, and a little friendly competition—all while helping support local nonprofit organizations serving Greater Nashua.

Your ticket includes an evening packed with fun:

• Karaoke all night long
• Halloween-themed games and activities
• Costume contest with prizes
• Incredible raffle baskets
• 50/50 raffle
• Festive surprises throughout the evening
• The opportunity to help support deserving local nonprofit organizations

One of the most unique parts of this event is that our attendees help decide choose a winning non-profit! Guests will have the opportunity to vote for one of several local nonprofit organizations, with the winning organization(s) receiving a donation from our club.

This is more than just a Halloween party—it's an opportunity to connect with your community, support local businesses, meet new people, and make a meaningful impact for organizations doing incredible work right here in Greater Nashua.

Costumes are highly encouraged (but not required!), so gather your friends, get creative, and come ready for a night of spooky fun!
