Katherine V. Excellent, LICSW

Writing your own biography is such an interesting & challenging task! I will start with my most valued identity, "Mommy.” I am the very proud mother of a soon-to-be 6-year-old boy who is of Irish and Haitian heritage. We have lived in the Tri-town for 10 years; our son is currently enrolled in the ORR district.

Professionally, I am a Licensed Independent Clinical Social Worker (LICSW). I earned my Master's of Social Work from Boston College in 2007 and have been a practicing psychotherapist since. I have worn many clinical hats over my career- I have worked in homes, pre-schools, elementary schools, and outpatient clinics as a therapist, consultant, and supervisor. I have worked as a Mental Health Professional for the MA Department of Corrections, based primarily at Walpole State Prison. Currently, I am the Clinical Director of a long-term, a hardware-secure treatment program for young men ages 16-21 who have committed violent crimes across the state, with the focus being rehabilitation and overcoming adversity.

Additionally, I have my own private practice where I provide therapy and clinical supervision. I have extensive clinical training in Race, Ethnicity, and Inclusion, which has been the heart of my career over the last 8 years. I am an REI trainer for the state. I have taught several workshops that discuss the role of systematic, structural, interpersonal, and internalized racism and strategies for confronting bias and learning to be aware of privilege and operate with cultural humility.



In my role, I have had the opportunity to work with children, youth, and families. So many of the people I have worked with have experienced significant racial trauma and been denied access to outlets and supports that serve as protective factors. As we know, access to protective factors greatly influences positive outcomes for young people. As a professional and as a mother to a bi-racial boy, I can strongly say that it is never too early to educate your children and develop a commitment to being anti-racist together.


I am so excited to support you in this journey!
