Currently she is the Clinical Director of the Program in Substance Use & Addiction Services (PSAS) established in the 2014 MGH Strategic Plan. She has worked collaboratively to reconceptualize, restructure and improve care provided to patients with substance use disorders throughout the hospital and in health centers throughout eastern Massachusetts.

Dr. Kane specializes in treating patients with co-morbid substance use and mental health disorders and their family members. She has advanced training in Cognitive and Dialectical Behavioral therapy, as well as in Cognitive Behavioral treatment for substance use disorders. She continues to provide training to medical students, interns, residents in both medicine and psychiatry, as well as to licensed professional staff.

Dawn Williamson, RN, DNP, PMHCNS-BC, CARN-AP

Dawn Williamson has over 30 years of nursing experience and is an Advanced Practice Nurse (APRN) for Addictions Consultation in the Emergency Department at the Massachusetts General Hospital. She responds to the treatment needs of both individuals and families with addiction and mental health issues in the emergency setting. She trains and supervises the clinical staff, develops, and implements policies relating to patient care, and aids with establishing treatment plans. She helped develop and implement multiple policies related to care of patients with substance use disorders (SUD). These procedures include evaluation standards and practice after ED admission for opioid overdose, management of acutely intoxicated patients, administering harm reduction measures, and methadone and buprenorphine initiation from the ED.

Ms. Williamson received her Doctorate in Nursing Practice from Regis College, her Masters in Science in Adult Mental Health Nursing from Northeastern University, and her BSN from the University of Massachusetts. She is Board Certified as a Clinical Specialist in Adult Psychiatric and Mental Health Nursing. She is also a Certified Advanced Practice Addictions Registered Nurse.

She has practiced in both outpatient and hospital settings in an expanded role that includes prescriptive authority. Serving as a preceptor to nurse practitioner students from the Institute of Health Professions, Vanderbilt University, and Regis College of Nursing, she strives to pass along knowledge. As faculty for MGH Addiction Fellowship Programs, she hopes to inspire others with a commitment to decreasing the stigma associated with SUD and to be change agents in our communities.

Dawn has authored and co-authored multiple book chapters and journal articles on SUD and on managing complex patients in the emergency setting. By remaining an active member of the Association for Multidisciplinary Education and Research in Substance use and Addiction (AMERSA), she works to promote the impact that nursing can have in battling addictive disorders. Ms. Williamson believes that this influence extends beyond the hospital walls. As part of MGH Global Nursing Fellowship she traveled to Tanzania to provide addictions training to health care workers. She continues to work with members of the Lakota Tribe in South Dakota on treatment approaches to SUD.

On a legislative level, an expertise in SUD led her to be one of two APRNs appointed by the Massachusetts Department of Public Health to a medical review group informing the state Prescription Monitoring Program. She has given numerous presentations on addiction and mental health treatment and strives to expand the use of evidence-based practices.
