About Our Tour Leaders

Tours are led by student leaders who are members of the Aggie Experience Council, chosen for their desire to help tell the Texas A&M story to a wide array of campus visitors.

They offer first-hand knowledge and insight into the outstanding academics and athletics, history and traditions, and a vibrant student life that set Texas A&M apart.

And while they come from many different backgrounds and hometowns, and have many different interests and career paths, they represent the Aggie family of more than 66,000 students in College Station and two branch campuses, and 450,000 former students around the world.


Aggie Experience Council members provide the following services to the campus and community:

  • Greet and provide information to campus visitors.
  • Lead campus walking tours for prospective students and their families, former students, and other university guests.
  • Participate in panel discussions about college life.
  • Serve as hosts for special university events.
