“

“The best part about working an event with Green Mtn. Concert Services is that their employees are trained professionals. Their involvement has done a great deal to make these events safe for all of those involved.”

-William J. Goggins, Director Education, Licensing & Enforcement Divisions Vermont Department of Liquor Control

Green Mountain has been our first-choice in security companies for large campus events, especially concerts, for years. The GMCS team is responsive and communicative – they understand our expectations and are quick to reach out or connect with our college staff if they have a question; they are a great partner with our Campus Safety team.

GMCS has been a great partner of ours for many, many years. From helping with parking and security for our 40+ special events a year, to supporting us during Vermont’s largest event, the 10 days of the Champlain Valley Fair, GMCS is always an integral part of our logistics here at the Champlain Valley Exposition.”

I have been honored to work with Green Mtn. Concert Services for many years because they are serious about safety.  They were active contributors to the American National Standards for crowd management and for event security, and their work on site shows that they practice what they preach.
