Medical Team

The mission of the Division of Substance Use Prevention and Harm Reduction’s Medical program is to improve healthcare for people who use substances in Philadelphia. The team provides clinical expertise in substance use disorder, harm reduction, and wound care within SUPHR, across City departments, and community organizations. They carry out capacity-building activities to support community organizations, hospitals, and City agencies to adopt evidence-based harm reduction clinical practices when engaging people who use substances. SUPHR’s medical team collaborates with and supports hospital-, community-, and government-based programs seeking to improve the care and well-being of people who use substances. The team convenes healthcare professionals and clinicians across Philadelphia to identify gaps in care, improve best practices, and identify emerging healthcare needs for people who use substances.

She brings this passion to SUPHR as she has brought it to Caribbean Community in Philadelphia, Bayada Hospice, and Conchester Animal Hospital in the past.
