Maryann Brooke Guernsey, LCSW


I went to Colby College and, in the days post-Watergate, transferred to Syracuse University where I dual majored in journalism and religion. I worked as a reporter and editor for about 15 years. I became interested in mental health issues after adopting children from international settings. Social work, with its emphasis on social justice and the importance of the environment/systems, seemed a very good fit. I received my MSW degree from the University of Maine.

I see myself very much as a “generalist” rather than a “specialist.” I have had training in TF-CBT, MATCH-ADTC, CBT (Beck Institute), Wraparound, adoption/foster care issues, Autism Spectrum Disorders, and Fetal Alcohol Spectrum Disorders. My care philosophy centers around seeing myself as something of a detective: filled with curiosity, some knowledge, and a true desire for collaboration.
