Malissa M. Barbosa, DO, Leads as Area Medical Director at CleanSlate Outpatient Addiction Medicine


As the number of deaths from synthetic opioids continue to climb across Florida, CleanSlate Outpatient Addiction Medicine helps those struggling with the disease of addiction in Orlando. CleanSlate is a national medical group which provides treatment for the chronic disease of addiction, primarily opioid and alcohol use disorders, through physician-led outpatient addiction treatment centers where patients receive medication-assisted treatment using the highest quality, evidence-based practices. Patients bear too much of the burden of finding treatment. We help solve this challenge by expanding access and outreach - co-locating with other providers, partnering with community organizations and payers, introducing new services, such as telehealth, to our centers and constantly enhancing our model to meet the evolving needs of patients.


Our Orlando efforts are led by Florida and Wisconsin Area Medical Director Malissa M. Barbosa, DO, a board-certified Family Physician and a fellowship-trained Addiction Medicine Specialist. Barbosa's medical education began at the Philadelphia College of Osteopathic Medicine. She continued her post-doctoral training at Nova Southeastern University/Larkin Community Hospital for residency and fellowship. Barbosa served as both chief resident and chief fellow for the Family Medicine and the Addiction Medicine programs, respectively. Barbosa went on to serve as a physician leader and champion within the Penn Medicine/Lancaster General Health System and the Orlando Veterans Administration Medical Center before she joined CleanSlate as Center Medical Director in December 2017.

As a leader, Barbosa has worked on various committees addressing patient care needs in the areas of acute and chronic pain syndromes while working within the mental health community to advocate for the standardization of care for acute withdrawal syndromes within the hospital setting. Barbosa serves in the following capacities: Board of Trustee member for the American Osteopathic Academy of Addiction Medicine, Assistant Professor of Family Medicine at the University of Central Florida College of Medicine, and member of the Clinical Care Advisory Committee for CleanSlate. In recognition of her leadership expertise, Dr. Barbosa was promoted to Area Medical Director within CleanSlate.

Barbosa is active in the Orlando community at-large through her participation on the Orange County Treatment Committee and Seminole County Drug Free Taskforce. She is also a public speaker and advocate providing education and information for professionals, patients, and families.
