Internal Medicine Residency Program


Welcome! The Internal Medicine Residency Program at NYC Health + Hospitals/Woodhull offers residents a chance to train with one of the most diverse and medically complicated populations in the United States. We provide the experience of a community-based program but have access to the resources of a large hospital system and the global population that lives in our communities. Our residents graduate well equipped to independently provide quality care to patients of any medical complexity. 

NYC Health + Hospitals/Woodhull is part of NYC Health + Hospitals, the largest public health system in the United States. Our 347-bed hospital is located in North Brooklyn at the literal intersection of three Health Professional Shortage Areas (HPSAs): the Bushwick, Bedford-Stuyvesant and East Williamsburg neighborhoods. We treat over 100,000 patients a year, most of whom are underserved and more than one-third are uninsured.  We care for all patients regardless of immigration status or ability to pay. Half of our patients were born outside the United States. Half of our patients are Hispanic, one-third Black, and less than 10% each White and Multiracial.  Our patients speak over 100 different languages, with Spanish being the most requested language.

Our Program boasts a friendly and diverse complement of residents with a broad range of medical interests, hobbies, and life experiences. Founded in 1982, we are ACGME accredited with 69 residents and almost 50 faculty dedicated to preparing our residents for any career in Internal Medicine. We are an academic affiliate of the NYU Grossman School of Medicine. Most of our residents are International Medical Graduates and hail from around the world.  Half of our residents pursue careers as general internists and half match into fellowships in Medicine subspecialties.

Our Program 

Our Program is structured in a “4+2” model with almost all rotations being 2 weeks in duration. Rotations in the “4” of the “4+2” include inpatient floors, critical care, elective, night rotations, or other inpatient experiences. Vacation will also occur during this time.  Every four weeks residents will return to their primary care practice for the “2” weeks of the “4+2.”  During their primary care weeks, a resident will serve as the primary care provider for a panel of patients at our Medical Center or one of our Community Health Centers.  This practice continues throughout the three years of residency.  Residents also participate in other outpatient medicine subspecialty practices of their choice during their primary care time.

Inpatient Training

Our inpatient floor rotations include rotations in a dedicated telemetry service, a non-telemetry floor service and a dedicated admitting team. Floor teams consist of a senior resident working with two interns or a senior resident functioning as a hospitalist by themselves.  After the day shift, floor patients are covered by a night-float service.  Attending hospitalists are present in-house 24/7. 

Our critical care services include a 12 bed Intensive Care Unit and a 12-bed step-down unit, each staffed with two residents at a time.  Care is split into a day shift and a night shift. There is no rotating call schedule.

Outpatient Training

In our medicine clinics, residents serve as the primary care physician for a panel of patients over the course of three years.  Each resident is part of a dedicated Patient Centered Medical Home (PCMH) team, working with the same group of attendings, nurses, staff, and patients throughout the course of their residency.  Some of our residents develop their primary care practices at nearby NYC Health + Hospitals community-based practices in the Williamsburg and Greenpoint neighborhoods.  


Each resident chooses rotations in medicine subspecialties during their Electives.  In addition, residents choose which medicine subspecialty clinics they practice in during their Primary Care rotations, allowing them to develop continuity in an outpatient specialty practice in addition to their general medicine practice during the course of their residency.  We offer electives in: Addiction Medicine, Anesthesiology, Cardiology, Endocrinology, Gastroenterology, Geriatrics, Hematology & Oncology, Hospitalist Medicine, Infectious Diseases, Nephrology, Palliative Medicine, Physical Medicine and Rehabilitation, Primary Care, Psychiatry, Pulmonology, Research, and Rheumatology. Our residents also pursue electives in other affiliated or nearby Medical Centers.


  • Morning Report: Our Program hosts Morning Report Monday through Thursday.  Morning report topics include overnight case presentations, case-based discussions, team-based learning, simulation sessions, and board review.  
  • Grand Rounds: Each Friday instead of Morning Report, the Department of Medicine hosts Grand Rounds. 
  • Departmental Conference: Each Wednesday, our residents join the rest of the Department of Medicine for noon conferences which include Morbidity & Mortality conference, Root Cause Analysis, Journal Club, and Quality Improvement conference.  
  • Academic Half-Day: Each week residents on floors, outpatient rotations, and electives participate in 3 hours of protected teaching time.  PGY1 residents have half day on Wednesday afternoon and PGY2 and PGY3 residents on Thursday afternoons. During the academic half day, our faculty lead discussions on three different topics. 
  • Primary Care Didactic: Residents on Primary Care rotations also participate in a second academic half day each week on Fridays. Led by our Primary Care faculty, these sessions focus on the physical exam and the management of common symptoms and chronic conditions.

Resident Life

What’s life like in Brooklyn?

Amazing! Woodhull is at the intersection of several unique and diverse neighborhoods with many options for cultural food and sights to visit. Manhattan is a short train ride away too for many of the most popular attractions from skyscrapers to Broadway and museums. Public transportation makes it easy to get around the city too or getting to one of several international airports for travel.


Our residents participate in simulation in central line placement, cardiac arrest protocols, and other acute care scenarios at Woodhull and with other hospitals within our health systems. Residents are part of a simulation team that run different clinical scenarios and learn point-of-care ultrasound (POCUS) skills during regular sessions throughout the year.


Our residents are very active in continued medical education (CME). Our affiliation with New York University makes it easy to participate in conferences in the latest research and clinical practice. In addition, our residents are members of various societies, and present their case presentations and research locally and nationally. 

Wellness Events

New York City and the surrounding area is home to activities for all interests. Wellness events take place during and after hours, and are programmed by program leadership and chief residents. Monthly birthday celebrations, access to coffee, and snacks are just part of what is offered throughout the month. 

CIR (Committee of Interns and Residents/Service Employees International Union)

All residents are part of CIR house staff union, and provide additional resources for education, medical, and professional needs. Additional information regarding benefits can be found via their website, https://www.cirseiu.org/woodhull-hospital/.

Enid Lopez
Program Coordinator

Enid has worked in the healthcare industry for over 20 years in an array of different positions in both the private and public sector. This has enabled her to understand the challenges that healthcare professionals face on a daily basis from different perspectives.  She has managed a large culturally diverse internal medicine program similar to Woodhull’s and a smaller family medicine program and found both experiences very rewarding. Enid joined NYC Health + Hospitals/Woodhull in 2015 in the quality management department and was fortunate to work closely with many Attendings and Residents from the Department of Medicine, but quickly learned she missed working with Residents. She has lived in this community for most of her life and therefore, has a comprehensive understanding of the social/economic and cultural dynamics that providers have to take into consideration when preparing healthcare plans for their patients. Enid is the proud mother of a daughter who travels the world as an unreal technical artist and of twin boys who are in their senior year of college. She and her husband will celebrate their 30th wedding anniversary shortly. Enid enjoys traveling, and spending time with her loving family and friends and serving as a mentor to others.

Cyrilla LeRiche-Jeanty
Program Coordinator

My name is Cyrilla Leriche-Jeanty, better known as Lilly. I am from St. Lucia. A paradise in the Caribbean surrounded by the Caribbean Sea and North Atlantic Ocean. I migrated to the United States approximately twenty-one years ago. I have been in the medical field for twenty years. First started at NYC Health + Hospitals/Kings County. I was there for a period of nine years during which time I obtained my Bachelor’s degree.

Upon completion of my bachelor’s degree I moved on to Mount Sinai Hospital. I then later came to the realization that I needed to revisit my plans for the future and decided to resign from my comfort oasis and reapply for a NYC Health + Hospitals position in order to secure my future. I joined the Woodhull Internal Medicine Residency Program family as a Residency Program Coordinator which has always been my dream job. Thus, I look forward to working alongside my superiors and peer to support the residents that I serve and the program to the best of my ability.
