Douglas Knapp, Clinical Director, MSN, APRN, PMHNP-BP,
Douglas Knapp, Clinical Director of SPARTA and a board-certified Psychiatric Mental Health Nurse Practitioner dedicated to helping individuals and families navigate adversity, trauma, and personal transformation. His work integrates evidence-based psychiatric care, performance psychology, nervous system regulation, and experiential healing practices to create meaningful and lasting change.
Doug earned his undergraduate and graduate nursing degrees from Jacksonville University and also holds a bachelor’s degree in psychology from Columbia College. Before entering mental health practice, he served for 10 years in the United States Navy, completing four combat deployments to Iraq and Afghanistan. Those experiences shaped his understanding of resilience, identity, leadership, and the profound psychological impact of chronic stress and trauma.
Following military service, Doug worked as a drug and alcohol counselor with the Indian Health Service, supporting Native American adolescents struggling with substance use disorders. His work combined modern addiction treatment approaches with culturally grounded and community-centered healing practices. He later served as an ICU nurse throughout the COVID-19 pandemic before returning to graduate school to specialize in psychiatry.
Doug’s clinical philosophy is rooted in the belief that healing occurs through connection, meaning, accountability, and the restoration of the human spirit. Through SPARTA, he helps individuals develop greater self-awareness, emotional resilience, nervous system regulation, and purpose-driven leadership. His approach blends psychotherapy, psychoeducation, mindfulness practices, physical challenge, and group process into an immersive transformational experience designed to foster long-term growth both individually and within the family system.
