Joseph O. Prewitt Diaz, PhD, is a practitioner-scholar who began his career as a public health worker in the depressed villages of his native Puerto Rico. He was formerly a professor at Pennsylvania State University, where he trained over 120 PhD-level educational leaders. He served as a mental health volunteer at some of the major disasters in the United States, among them the Oklahoma City Bombing and the 9/11 United Recovery in Shanksville, PA. In 1998, he was assigned to International Disaster Services where he implemented mental health and community psychosocial support programs in South America and Southeast Asia. He has worked in over 57 countries as the mental health technical expert for the IFRC/ COVID-19 work group. During his years of service, he received multiple national and international awards for his service, research, and scholarly contributions.

"An essential read for both mental health and psychosocial support professionals, as well as disaster and crisis leaders and practitioners. Dr. Prewitt Diaz weaves together framing and subject matter expertise that builds on academic research pre-COVID-19 pandemic, emergent literature from 2020 and 2021, as well as key case studies. Most relevant, Dr. Prewitt played a key leadership role in the IFRC America’s COVID-19 operation, supporting the 35 countries that make up the region in designing and implementing robust mental health and psychosocial support programming. . . . Thank you for this vital contribution to the robust mental health and psychosocial support field!"—From the Foreword by Dr. Jono Anzalone, Executive Director at The Climate Initiative, Portland, Maine
