WASHINGTON – Georgetown University Athletics welcomed a pair of new staff members this month. Dr. Marcus Edward Dumas, Psy.D., CMPC joined the team as the Department's Amato Family Head of Athletic Counseling Services. Additionally, Lisa Perrett came to the Hilltop as GU's Director of Sports Nutrition. Both positions are funded thanks to the generosity of Georgetown donors.
 
The work of both positions is accessible to all Georgetown student-athletes, and allows the Department to continue its holistic approach to formation. Dr. Dumas leads staff that performs individual counseling, crisis intervention, consultation, outreach programming and collaborative care. Perrett works closely with Sports Medicine, Sports Performance and coaches to optimize 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."
