Executive Team Members

Dr. Monteic Sizer, Executive Director

Dr. Monteic A. Sizer serves as Executive Director of Northeast Delta Human Services Authority (Northeast Delta HSA). He joined the organization in May 2013 as its first Executive Director. He is uniquely qualified to advocate on behalf of citizens located in the twelve Northeast Delta HSA parishes he represents because he exemplifies how people can meet their greatest human potential based on accountability, integrity and a willingness to engage in their own lives.

His vision for transforming Northeast Delta HSA into an innovative entity has already begun with the integration of previously disparate mental health, developmental disability, prevention and addictive disorder services. Under his leadership, Northeast Delta HSA is increasing efficiencies for improved clinical accessibility, centralized operations, organizational accountability and improved partner and provider relationships.

Dr. Sizer has established three tenets for Northeast Delta HSA and its partners: to provide excellent customer service, greater access to services and competent, quality care.

Prior to his Northeast Delta HSA appointment, Dr. Sizer served as the President and CEO of the Louisiana Family Recovery Corps, a long-term disaster recovery organization created by the state of Louisiana after Hurricane Katrina. Dr. Sizer also served as a National Consultant and Subject Matter Expert with the U.S. Department of Health and Human Services. Additionally, Dr. Sizer has deep professional experience in organized philanthropy, politics, educational reform and has been leader of several large health and human services organizations. Dr. Sizer is also a consultant and sought after keynote speaker. Dr. Sizer’s expertise enables him to speak practically about relevant policies, procedures and programs needed to help advance causes of the poor, working class and related vulnerable populations.

Dr. Sizer’s academic research and professional experiences as a clinical-community psychologist serving poor and underserved populations in educational settings, community-based mental health centers, prisons and forensic hospitals, have given him a profound knowledge of administrative, systems and public policy challenges impacting poor and working class Americans. Some of Dr. Sizer’s academic research examined the correlation between home, school and community influences on academic achievement, African American homicide, crime and causes of community instability. Dr. Sizer is also a leader in behavioral and primary healthcare integration.

Dr. Sizer is a 2010 Leadership Louisiana graduate, a Leadership Fellow with the Effective Leadership Program at the Center of Leadership and Public Values at Duke University and the College of Business at Southern University (Baton Rouge), and a Political Fellow and former member of the Board of Directors of the North Carolina Institute of Political Leadership.  Dr. Sizer also participated in the Executive Training Institute at Vanderbilt University and the Leadership in Non-Profit Management Program at the University of North Carolina at Charlotte.
