Healing, Scholarship & Artistry

I grew up in St. Louis, Missouri, shaped by years at OSRUI summer camp and a love of water polo at John Burroughs School. At Georgetown University's School of Foreign Service I studied Science, Technology & International Affairs, graduating Magna Cum Laude with Honors in my major. I discovered that music, community, and medicine are deeply intertwined—leading Kabbalat Shabbat services and growing our Jewish community from 20 to 65–80 attendees each week.

After college I spent transformative time at the Pardes Institute of Jewish Studies in Jerusalem on a funded academic fellowship before entering Georgetown University School of Medicine. I earned my MD in 2023 and matched into internal medicine at Beth Israel Deaconess Medical Center, a Harvard teaching hospital.

I currently see patients as a primary-care physician at Fenway Health in Boston while pursuing research in cardiovascular outcomes, health equity, and AI-assisted diagnostics. I am also a co-founder of CATALYST, an AI startup developing LLM-based ECG interpretation tools. Outside the hospital, I write and perform folk music and remain active in Jewish communal life.

"Judaism is a fundamental part of my identity. Playing guitar at the bedside for cancer patients during college showed me that healing and music are not so different—they both require presence, vulnerability, and the courage to sit with another person in their most human moments."
— Jason Gusdorf, Pardes Institute Blog

Judaism as a Way of Life

Growing up in a Reform Jewish household in St. Louis and attending OSRUI summer camp for seven years, Judaism has always been central to my life—not merely as religion but as an integrated framework for ethics, community, and purpose.

At Georgetown I served as the Jewish community's music leader for four years, leading Kabbalat Shabbat services that grew from roughly 20 participants to 65–80 each week. I launched a Torah-study program and helped secure new Torah scrolls and prayer books for the community.

Before medical school, I received a funded fellowship to study at the Pardes Institute of Jewish Studies in Jerusalem, returning later for an extended fellowship. That intensive immersion in Jewish text deepened my understanding of the spiritual dimensions of healing—themes that directly inform my clinical practice and academic writing, including a published essay on how Judaism shaped my love of medicine.
