WASHINGTON – Georgetown University Athletics has added two new members to its staff this month. Dr. Marcus Edward Dumas, Psy.D., CMPC, has joined the department as the Amato Family Head of Athletic Counseling Services, while Lisa Perrett has arrived on the Hilltop as Georgetown’s Director of Sports Nutrition. Both positions are made possible through the generosity of Georgetown donors.
The services provided through both roles are available to all Georgetown student-athletes and further the department’s commitment to a holistic approach to student-athlete development. Dr. Dumas oversees a staff responsible for individual counseling, crisis intervention, consultation, outreach initiatives and coordinated care. Perrett partners with Sports Medicine, Sports Performance and coaching staffs to help maximize student-athletes’ health, recovery and performance.
“Our mental health and nutrition positions do more than shape competitors, they build the whole person,” said Francis X. Rienzo Director of Intercollegiate Athletics Lee Reed. “Thanks to the powerful vision of our donors, we provide the resources for student-athletes to thrive in both mind and body, empowering them to become the healthiest, most complete versions of themselves.”

The Amato Family Head of Athletic Counseling Services
Dr. Marcus Edward Dumas, known as Dr. Du, will oversee Georgetown’s athletic counseling program while providing comprehensive mental health support to student-athletes. He will work alongside Georgetown University’s Counseling and Psychiatric Service (CAPS), Sports Medicine personnel, coaches and athletics administrators.
A licensed psychologist and Certified Mental Performance Consultant (CMPC), Dr. Du specializes in the intersection of mental health, human performance, leadership and athlete development.

Earlier in his career, he completed his postdoctoral fellowship at the University of Southern California.
A former Division I football student-athlete himself, Dr. Du combines personal experience with his clinical background. His professional approach is based on the idea that genuine relationships are essential to meaningful growth and that psychological well-being and excellence can complement one another. He is committed to helping student-athletes handle the challenges of college athletics while building the resilience, self-awareness and skills necessary to succeed both during and after their playing careers.
A native of South Vacherie, Louisiana, Dr. Du earned his bachelor’s degree from the University of Central Arkansas, where he competed in Division I football. He later received his doctorate in counseling psychology from Springfield College.
