Preliminary Residency

Our preliminary program is designed to provide a solid one-year foundation in clinical medicine for those entering other specialties. You will receive a rigorous and thorough basic training in Internal Medicine, with rotations on general inpatient medicine, HIV medicine, cardiology, and critical care medicine. By the end of training, graduates of our preliminary program are capable of managing most medical conditions. Additionally, all preliminary interns will have at least eight weeks of call-free elective time during the year which can be spent in the Internal Medicine subspecialties, non-medical subspecialties (such as Radiology), and can be completed at any of the campuses in the Mount Sinai Health System.

A typical Preliminary Schedule is as follows:

Housestaff Stories

Charles Scott, MD, PGY 1 (2015-2016)

Preliminary Medicine at Mount Sinai West/St. Luke's has provided me a solid foundation in medical management to take into my advanced training program. Working in a busy NYC hospital with a diverse patient population has been both challenging and confidence-building, and the team-like environment among the IM house staff and faculty has made my experience here especially rewarding. I would 100% choose MSW/SL for Preliminary Medicine if I had the decision to make again.


Alice Zheng, MD, MPH, MBA, PGY1 (2015-2016)

MSSL and MSW was my top choice and I have been thrilled with this past year. You have a diverse patient population spanning Midwest to Harlem.  The program also feels like a smaller family within a larger Sinai one, where leadership/administrators are friendly and easy to access.  There is great flexibility as well in the elective blocks to pursue your unique interests.  Lifestyle-wise, I loved living here, a stone’s throw away from the Riverside Park, Lincoln Center and Hell’s Kitchen.  Can’t beat that package!
