Alexander Diaz de Villalvilla, MD
Clinical Assistant Professor of Medicine

After finishing my Med-Peds residency training at Brown in 2012, I stayed on in the Brown General Internal Medicine Division as a teaching attending on wards and clinic. Seeking more direct patient care, I moved to Montefiore in the Bronx, New York, working as a primary care physician in General Pediatrics and Internal Medicine, and teaching residents and med students, which was a great privilege and educational challenge. I returned to the Rhode Island area in June 2019 to work at Medical Associates of Rhode Island (MARI) / Bristol Medical Center as a full-time adult PCP,  and work on being a more efficient, streamlined, and effective doctor. Thankfully, I have returned to teaching on wards and the Doctoring Program at Alpert Medical School of Brown University. This has allowed me to continue my interests in teaching physical diagnosis and the doctor-patient encounter, and follow some of my broad generalist urges while maintaining my love of medical esoterica and difficult diagnoses.

This program is the oldest hospitalist program in the state, and he became the first hospitalist in Rhode Island to become a dedicated nocturnist. For several years, aside from the ER staff he was the only attending physician actually in-house at Rhode Island Hospital. He often notes with irony that he has essentially become a professional intern for life, but with power! Outside of medicine, he lives in Barrington, RI, raising and supporting his 7 children.
