As a non-traditional college student in my early 50s, living and working in the Pacific Island of Guam, choosing the right program for graduate studies was very important to me. The process of selecting the right program was intentional – it had to offer a diverse student population, professors with real-life experiences, a safe space to share cultural perspectives, and a curriculum that offered classes that were aligned with students’ educational and professional goals. The Great Plains IDEA program met and exceeded all my expectations. Concepts from every course have been applied in my profession to the extent that it has aided in the expansion of our services and the population we serve. As I reflect on these successes, I attribute much of it to the genuine care of the GP IDEA professors who were as passionate about the success of each student as they were in the subjects they taught. GP IDEA was definitely the right program for me!
