Currently pursuing his PhD in Clinical Psychology at Seattle Pacific University with a focus on sport psychology and athlete mental health, he conducts cutting-edge research on athletic identity, mindfulness interventions, and personality factors in performance contexts. His partnership with SCI centers on conducting DISC behavioral assessments and implementing the Sports Playbook Team Culture Model to help individuals and teams optimize their performance through enhanced self-awareness and strategic team development.

Mills’ distinctive background combines six years of business strategy and analytics experience with the Philadelphia 76ers (NBA) and New Jersey Devils (NHL) with advanced training in sport and performance psychology.

He leverages DISC profiling to identify individual behavioral tendencies, optimize team composition, and prevent destructive conflict before it emerges. His involvement with the Sports Playbook Team Culture Model—based on the comprehensive framework developed by Gordon, Furlong, and Pendleton—helps organizations move from chaos to sustainable peak performance. By combining rigorous research methodology with practical sports industry experience, Mills provides evidence-based solutions that enhance team dynamics, improve communication patterns, and establish cultures of sustained excellence.
