Brown's academic degree offerings include a Master of Social Work (MSW), a Master of Public Health (MPH), a PhD in Social Work, and a PhD in Public Health Sciences. It is currently ranked first among Master of Social Work programs in the United States. The school was endowed by Bettie Bofinger Brown and named for her husband, George Warren Brown, a St. Louis philanthropist and co-founder of the Brown Shoe Company.
