    A lifelong Marylander, Sanjay grew up in Germantown, MD and attended a high school program focusing on environmental science. He went to the University of Maryland, College Park for his bachelor’s degree and spent his free time singing a cappella, including recording an album that is now on Spotify. He then attended the University of Maryland Baltimore for medical school where he participated in research on direct acting antivirals in HIV/Hepatitis C co-infected patients and did rotations in Lusaka, Zambia and Shiprock, New Mexico.

Besides medicine, his other loves include bubble tea, coffee shops, board games, time with his family, and watching too many movies in the theater.

    Samantha Rosenblum

    Med/Peds PGY4

    Samm grew up in Sharon, MA and went on to attend undergrad at Northwestern University, where she studied journalism at the Medill School of Journalism with a minor in global health studies. Studying journalism encouraged her lifelong interest in learning peoples’ stories, a large factor in her decision to pursue medicine. She then spent one year working at Massachusetts General Hospital as a clinical research coordinator in thoracic oncology. Samm attended medical school at the Boston University School of Medicine where she served as the head of the medical humanities interest group and developed a course curriculum on narrative medicine for fourth year medical students. During medical school she had the opportunity to work with multiple med/peds providers and felt connected to their overall approach to patient care. While she is  excited by the many directions she can take with med/peds, she is currently excited about using narrative medicine as a tool to improve patients’ transition from pediatrics to the world of adult medicine. When she’s not at the hospital, Samm can be found reading, hiking, doing yoga, and making greeting cards for her friends and family.
