UT Public Safety to Recognize Its Veterans during November

More than 20 employees of UT Public Safety have served across all branches of the US armed forces. Throughout the month of November—and in observance of Veterans Day—we will recognize those employees for their dedication to our country and the University of Tennessee.

These employees work in all units of UT Public Safety, including the UT Police Department, Emergency Management, and Environmental Health and Safety.

You will learn about their work in the military and about their current roles at UT.
