Justin completed his anatomic and clinical pathology residency and surgical pathology fellowship at Stanford.

During his fellowship training he participated in the Program in Innovation and Entrepreneurship at the Stanford Graduate School of Business.  Justin grew up in Brooklyn and attended medical school at Upstate Medical University in Syracuse, NY where he graduated Magna Cum Laude and was elected to Alpha Omega Alpha, the national medical honor society. Justin is a passionate jazz collector with a particular focus on the 50-60’s, a time that coincides with the widespread adoption of the LP. This provided an amazing opportunity to document a dynamic and exciting time in music (one that parallels 19th century Vienna) marked by immense creativity in musical composition and design. Since he wasn’t in New York at the time, the second best way to experience the music is on vinyl with low powered tube amps. Oh, he also collects Nebbiolo.
