James McKowen, Ph.D.

I’m a Clinical Psychologist, Assistant Professor of Psychiatry at Massachusetts General Hospital and Harvard Medical School, and Clinical Director of an outpatient addiction program. My clinical work focuses primarily on helping young people and families navigate substance use and mental health challenges through structured, evidence-based approaches. I have particular expertise in working with parents, helping them develop practical skills and strategies to support their child’s recovery. I also provide treatment for anxiety, depression, mood disorders, and other mental health concerns affecting youth and young adults.

Alongside my clinical work in addiction and mental health, I focus on the growing mental health impacts of climate change. I provide climate-informed therapy for individuals experiencing distress related to the climate crisis and work with organizations, clinicians, and communities to better understand and respond to these emerging mental health challenges.

Outside of my therapy practice, I lead research examining substance use, youth mental health, and the psychological impacts of climate change. I also work with organizations to apply behavioral science to climate-conscious sustainability and regularly speak, teach, and collaborate on writing and educational projects focused on the intersection of mental health, addiction, and climate change.

Never forget that you are one of a kind. Never forget that if there weren’t any need for you in all your uniquness to be on this earth, you wouldn’t be here in the first place. And never forget, no matter how overwhelming life’s challenges and problems seem to be, that one person can make a difference in the world. In fact, it is always because of one person that all changes that matter in the world came about. So be that one person.

(Petras and Petras, 2009)
