Co-Founder & Licensed Psychologist
Dr. Patrick Mullen, Psy.D.
Dr. Patrick Mullen is an expert in the treatment of substance use and co-occurring mental health conditions, with a focus on emerging adulthood, mood and anxiety disorders, and the intersection of psychological and physical health. His clinical work integrates Acceptance and Commitment Therapy (ACT) and related process-based approaches that target the underlying patterns that keep people stuck and the positive drivers of change that move them forward.
Dr. Mullen has extensive experience across the continuum of care—from inpatient and residential treatment to outpatient and community-based recovery support. He has served in clinical leadership roles overseeing multidisciplinary teams and developing innovative, whole-person programs that bridge mental health, substance use, and medical care. His practice emphasizes collaboration, relational depth, and helping clients build a life centered in agency, purpose, stability, and self-compassion.
In addition to his clinical work, Dr. Mullen is the founder of Mullen Health Strategies, a behavioral health consulting firm advancing integrated care models for employers, health systems, and recovery organizations. He has published and presented on behavioral health economics, integrated primary care, and the role of peer support in long-term recovery outcomes.
Dr. Mullen earned two master's degrees as well as a doctoral degree in Clinical Psychology from the Philadelphia College of Osteopathic Medicine, where he also completed advanced training in health psychology and integrated behavioral health. His dissertation research and continued study focus on addiction, from the individual level to the social and community conditions that shape both its course and its treatment.
