Meet The Staff

We think our team is the best in the business and we love working together. If you stop by our office at lunchtime, you will find us gathered to talk recipes, pets, hobbies, family stories and (ok, we admit it) student travel.
  • Judi & Dennis


    Judi and Dennis formed ETSI in 1988. Together they combined well over three decades of service and experience in education, leadership training and student travel to provide high quality, educational experiences to students through travel. Now (mostly) retired, they are enjoying opportunities to travel on their own, spend time with friends and enjoy their grandchildren, Jackson, Amelia, Maddie and Max.

  • Julie Sabala

    Vice President

    Julie has been part of the business pretty much since birth. Daughter of the owners, the travel bug bit her early. She loves providing tours to students and sharing her love of travel and history. When not planning music tours or handling the financial side of the business, she can be found with her children–riding horses, skiing and of course, traveling!
