Matthew E Nilsson, MD

Child and Adolescent Psychiatry

In 2021, I completed my Child and Adolescent Psychiatry Fellowship and Adult Psychiatry Residency from Maine Medical Center. My clinical interests include understanding and mitigating stigma in mental illness and the treatment of disturbances related to autism spectrum disorder, early onset psychosis, ADHD, anxiety, depression and bipolar disorder.

My hope is to walk alongside individuals and their families on their journey of recovery and to help each person and family to achieve their full potential.
