Graduate Program Director
Assistant Professor of Psychology
I am licensed as a clinical psychologist and have actively served and worked in direct service, supervision, consulting, teaching, and research. I joined the faculty at East Texas Baptist University in 2011, where I have primarily facilitated courses in counseling and clinical psychology. I have over ten years of experience providing psychological services to adults, children, and families. More recently, I have been consulting with non-profit clinics that provide assessment and intervention to uninsured and underinsured children and their families. I am a husband, and I have two wonderful children. My clinical and research interests are diverse. I have published research in the areas of God-concept and the connection between spirituality and resilience. I have served on a national task force within the American Psychological Association for promoting psychological literacy. More recently, I have been involved in research on the use of Christian Cognitive Therapy among older adults with dementia. I have specialized in consulting with and providing treatment to children diagnosed with Reactive Attachment Disorder within specialized foster care settings. I have frequently provided invited talks related to assessment and treatment of Reactive Attachment Disorder. I have previously specialized in pediatric forensic evaluation, and have become a court expert in multiple jurisdictions.
"Two things I ask of You, Lord; do not refuse me before I die: Keep falsehood and lies far from me; give me neither poverty nor riches, but give me only my daily bread. Otherwise, I may have too much and disown You and say, ‘Who is the Lord?’ Or I may become poor and steal, and so dishonor the name of my God." (Proverbs 30:7-9)
