Dr. Chatterjee moved to Illinois last year from California, where she was active in the California Society of Addiction Medicine (CSAM) and chaired the CSAM 2020 State of the Art Conference. She retired last year from San Mateo County Health, where she had worked since 2008, most recently as Interim Medical Director and Deputy Medical Director in the division of Behavioral Health and Recovery Services (BHRS). BHRS offers outpatient, inpatient, residential, rehabilitation, withdrawal management, and medication for addiction treatment for the safety net population of San Mateo County, serving an average of 15,000 individuals annually.

She also founded an Addiction Medicine work group that included the Public Health Officer, physicians from the ED, Psychiatry, and Primary Care, therapists, and case managers. This group successfully advocated for the prescribing of buprenorphine in the ED, Primary Care, Mental Health Clinics, and the two jails, and wrote guidelines for extended-release naltrexone for alcohol use disorder and benzodiazepine tapers.
