Your GMT Team

Our seasoned staff of over 30 professionals has been with us on average over 10 years each.  Their hands-on band and choir program experience is ready to make your performance travel better than you could ever imagine!


Your first GMT contact will be with a member of our sales team. Their job is to help you determine what your performance-trip needs are, and how to plan the perfect trip. Our sales team will coordinate with our other staff members to guarantee a smooth, successful trip.

Travel Directors

Each GMT trip is accompanied by knowledgeable on-site Travel Directors.  They will meet your performers, and make sure their experience during their trip is safe, pleasant and without problems; allowing you to focus on your students and their performance preparation.  If you choose to have friends and family travel as well, they will have a Travel Director accompany them the entire trip.


Our marketing team provides custom-designed print and digital collateral for your staff and students.  From websites, landing pages, digital forms, to printed flyers, posters, leave-at-homes, and phone applications – they provide it all, branded to your school!
