Meet Our McDonough Student Ambassadors

Meet this year’s McDonough Student Ambassadors, who represent the undergraduate and graduate experience at Georgetown’s McDonough School of Business, highlight their academic and professional journey on the Hilltop, and facilitate student engagement within the broader McDonough community. 

The McDonough Student Ambassadors span seven different degree programs and include a diverse array of personal and professional experiences – from student-athletes to veterans to executives to sustainability advocates and more.  

Meet the 2024-2025 McDonough Student Ambassadors and learn more about why they joined the Hoya community:
