Hear From Our MAS Students and Alumni
"The MAS program served as the perfect source of inspiration for me. Despite being a distance learning course, the interaction with faculty and classmates both in asynchronous and synchronous fashion felt as if I was attending the course in person. The modules and assignments were perfectly designed for working professionals with a background knowledge in the area. Thanks to this program, I have found a role that I really love in the health policy space while continuing my work as a clinician part time. Thank you, OPAL, for such an amazing and fruitful experience!"
