Our Executive Team

Dr. Jan Roberts, LCSW: CEO & Director of Translational Research


Jan Roberts is a co-founder for IRCCMH and serves as CEO and Director of Translational Research. Ms. Roberts is a Licensed Clinical Social Worker who owns and operates one of the largest collaborative care practices in the mid-Atlantic region, Partners in Health and Wellbeing. Ms. Roberts is a clinician and an entrepreneur with an activist spirit who has extensive experience running both non-profit and for-profit healthcare organizations. 

Dr. Roberts teaches at NYU Silver School of Social Work and is currently working on a funded study of Mental Health Clinicians and Knowledge and Attitudes on Cannabis.  She is also Guest-Editor for a Special Issue on Cannabis and Mental Health for the Clinical Social Work Journal (CSWJ).  

In addition to providing care to patients at her practices in Manhattan and Delaware, Ms. Roberts is one of the founders of the first integrative care center in Delaware,  Integrative Health Delaware- A Center for Health and Research.  

Dr. Roberts' decision to create IRCCMH resulted from her dedication to provide her patients with the most current research to improve their mood regulation and to create a sense of well-being. Her current interest is on the clinical application of cannabis in mental health settings and focusing on maladaptive coping strategies rather than a substance-based approach to treating addictions. As a result, Ms. Roberts is especially interested in educating fellow mental health clinicians on the most recent research findings to address stigma and lack of knowledge related to cannabis, the endocannabinoid system and mental health outcomes. She keenly believes that research should influence policy not vice-versa.
