At IGA, diversity isn't just a corporate buzzword. It is the way we work, and it comes through in everything we do. From the high-performing instructors, to the educational services we provide, IGA advocates unique thinking and instructing with the most up-to-date curriculum. We have become the top training and certifying school by creating an inclusive environment fueled by innovative ideas and teaching methods.

Our instructors have diverse cultural backgrounds, beliefs, perspectives, and lifestyles. Yet they all have one thing in common - their ability to excel in the Travel and Tourism industry and impart that knowledge to the students. Currently we are working not just to expand the number of international locations you can choose to receive your training but maintaining the most up-to-date curriculum taught by the very best instructors.

It is an educational process that works best for more people in more ways than ever. A goal with this kind of magnitude requires the brightest, most forward-thinking minds around. We have them here at IGA and they are making a difference in our programs and students lives.

All of the instructors are carefully chosen for their world-class teaching abilities and industry backgrounds. IGA utilizes this group of instructors in your programs. They have more than 400 years of combined International Tour Managing and Tour Guiding experiences including motorcoach tours, railroad tours, cruise ship assignments, owning their own Tour Operating companies and Destination Management companies, teaching, industry speakers, published authors and photographers, as well as designing and marketing tours for major companies. They can offer insights that only come from years of working in the industry and your instructors clearly care about the student's needs and provide them with real travel experiences that engage, enrich and inspire. They are ALL graduates of the International Guide Academy and are actively working in the areas they instruct. They bring their domestic and international experiences to the classroom and are experts in their field. The core of your programs are to encourage you to develop your knowledge and skills through the guidance and leadership of the instructors and by the use of such sessions as actual motorcoach trips, group and individual problem solving, research techniques, individual student presentations, walking tours, airport visits, day trips, visits to the classroom by leaders in the industry, etc.

When asked "Where is the favorite part of the world in which you travel?", I usually reply: "Wherever I am at that time". I know that the world is always changing and, even when I do the same tour back-to-back, I and my passengers can see completely different things from the prior tour. My passengers see and experience different aspects of all the places visited. As for myself, I love to see my passengers enjoying themselves and I get to share their happiness while I ensure the smooth flow of the tour and provide the entertainment and education of their tour as well as all the work required behind the scenes, so to speak, to insure they have a vacation of a lifetime. That is my job and that is what is expected by the Tour Operators that hire me. It is truly the best job in the world."

Taking the IGA course really helped me hone my skills. I even had to admit and correct a few things I had been doing wrong from the start! What I liked best about the Tour Director course is that it’s designed to take you where you are, be it experienced or a novice, and raise you up to the next level.” He has instructed in the programs in the USA and Mexico.

They state "Guests are always intrigued with our story of leaving the "Corporate Environment" and how we got into this field.  We tell them that we went "back to scool" and that IGA provided us with the tools and functional skills we needed to feel confident in being successful".  Their passion for travel and delivering a memorable travel experience to their guests attributes to their success.  Their experiences offer students insights into the cruise ship industry, a career in which IGA graduates are able to pursue after their certification.
