Internal Medicine Residency


Welcome to Danbury Hospital’s Internal Medicine Program! As a three year categorical medicine program, we aim to train competent, compassionate and well-rounded physicians. Our graduates are prepared to provide excellent patient-centered care as they take their next career step, whether entering general practice or pursuing further subspecialty training.

Being a Yale School of Medicine affiliated program, our residents have a hybrid opportunity to learn from experts in academic medicine each week, while being able to train in a community-hospital setting. Our housestaff additionally serve as clinical instructors for the University of Vermont, providing residents the valuable opportunity to develop teaching skills. Combined with our growing research department and Global Health Initiative, we believe our program strongly encourages residents to be equipped with both knowledge for the medical boards, and prepares them to become lifelong learners. 

Mission/ Vision Statement

The mission of the Internal Medicine program at Danbury Hospital is to provide our residents an outstanding educational experience to ensure that they are prepared to practice general internal medicine or to enter subspecialty fellowship training.  This is done by educating them in the essentials of clinical medicine along with the necessary pathophysiology and basic science required of a knowledgeable and skillful physician.  The residents are taught to deliver health services, regardless of a patients’ ability to pay, to a diverse patient population without regard to race, gender, sexual orientation, or social status.  The program requires and supports our residents’ role as teachers and educators in their interactions with their peers, students, ancillary medical professionals, and patients.  In addition, the program supports the professional development of our residents allowing for personal growth and individualization of goals.

Our three-year categorical medicine program is designed to equip residents for a career in general Internal Medicine or medicine subspecialities. Therefore, our curriculum focuses on providing a broad array of rotations to allow optimal opportunity for learning during training. 

Our curriculum is designed using a “4+2” schedule, meaning that residents participate in 4 weeks of inpatient rotations/subspecialty electives, followed by 2 weeks of outpatient continuity clinic or elective. This allows for residents to have a more balanced schedule in regards to teaching opportunity as well as work-life balance. 

Residents are additionally required to complete 4 weeks of Emergency Medicine, 4 weeks of Neurology & 4 weeks of Geriatrics, in accordance with ACGME regulations. 

Lastly, for residents interested in Global Health, a 6-week international elective can be completed in your second or third year. Please see Global Health for more information.

Danbury Hospital’s Internal Medicine residency program ensures that all residents have opportunities to gain knowledge and skills in the areas of clinical research, evidence-based medicine, and quality improvement. From the beginning of the intern year, our residents are involved in research seminars that are conducted throughout the year and cover essential principles of the research process. In addition, our journal club puts learned skills into practice by using the published literature to dissect multiple examples of research design and practice applying research findings to patient care.

Our residents are then encouraged to utilize this knowledge to design their own research and quality-improvement projects. The scholarly activities are fully supported by the residency program and Department of Research and Innovation, including assistance with IRB submission, statistical support, and dedicated research time. The Residency Research Director and other faculty provide close mentorship throughout the project development and execution.

Our Annual Joseph L. Belksy, MD Research Day offers an excellent opportunity not only to share results of the work with colleagues, but also to practice presentation skills. Many of our residents have presented their original research at regional, national, and international meetings.

Current research projects span a wide spectrum of research designs and areas of medicine, to include epidemiological studies, cohort studies, case-controlled studies, and randomized clinical trials in the areas of infectious disease, pulmonology, critical care, sleep medicine, cardiology, and rheumatology.

Danbury Hospital Internal Medicine residency program is a wonderful environment of curiosity and inquiry that inspires professional growth and can make the residency time truly memorable.

Current Danbury Hospital Internal Medicine Residents Highlights

Harold Cedeño, MDHarold Cedeo

I attended Pontificia Universidad Católica Madre y Maestra for Medical School in the Dominican Republic and even before then I realized I wanted to have a career in academic medicine. When I interviewed, I was awed by the exceptional support residents had from the faculty. I wanted a punctilious educational environment where my career goals would be supported and my co-residents will become a family. I must say that one of my favorite things about this program, is living in a small city that reminds me of my home in Dominican Republic. This aspect allowed me to blend easily, feel like I know everyone, and made the transition to a new country much less challenging. Danbury Internal Medicine is a smaller program that allows your voice to be heard yet large enough to allow you to see a wide spectrum of diseases from all around New England. I can attest for that as I will be staying one more year as a Chief Resident! 

Nichole Brunton, DOHarold Cedeo

Selecting Danbury Hospital for residency was a natural choice after my experience on interview day. My husband and I had interviewed at Danbury as a couple, and after meeting the teams for both of our programs, it was clear that this was a place we would love to be. Not only does Danbury offer an incredible learning experience for internal medicine, offering excellent didactics and university-level training in a community setting due to our Yale affiliation, but it is an incredibly welcoming environment. Our attendings are constantly working to teach us at every opportunity and encourage us to pursue research to expand our knowledge. Since being at Danbury, I continue to be impressed by the opportunities to learn and grow as an internist. I am most grateful to have such supportive program leadership, one that continuously advocates for the best education for our residents and cares about our well-being.

Akash J Shah, MDHarold Cedeo

Choosing Danbury Hospital as a home for my residency was made from a series of events and experiences. I attended Ross University for medical school and had the opportunity to complete MS3 and MS4 clinical rotations alongside AUC and UVM students at this program. During those rotations I found the residents I worked with to be engaging, down to earth and enthusiastic. The attendings, many of whom had graduated from the program, created a calm learning environment and treated the residents and medical students as colleagues part of a team with an open door attitude. The environment surrounding Danbury and the community it served ensured a peaceful yet diverse place to practice. The residency program at Danbury has ensured my education in the field of medicine grows steadily through active teaching on the medical floors/clinics, journal clubs, morning report and interactive academic sessions. Nuvance Health as a network of 7 hospitals and multiple ambulatory offices, has surrounded me with opportunities to engage in innovative projects taking medicine to the forefront of technology. I have been enthralled by the countless research and quality improvement projects our colleagues start, complete and publish during their path. I had a chance to compete in network wide competitions such as the Spark Tank and Belsky day while engaging in several leadership opportunities. Overall, this program has fulfilled the quest for a residency program with a strong educational foundation but also electrified all of our colleagues to find and foster their passion toward their intended career path.  

Mingwei Yu, MDHarold Cedeo

I was born and raised in China where my fascination in Medicine was first ignited in my early childhood. I would listen to my mother, a psychiatrist, share stories about patient care. The interest in basic science and patient care inspired me to peruse a career in medicine and I went on to receive several years of research training after graduating from medical school. The chance to be able to provide quality patient care with compassion, obtain exposure to great research opportunities and diverse patient demographics, and enhance my skills as a physician were key reasons that I chose Danbury Hospital as the place for my residency training. Throughout my intern year, I have come to realize that Danbury Hospital has afforded me incredible opportunities for both personal and professional growth. I especially enjoyed the family-like environment among residents in our program. We share the common goal of providing the highest caliber of healthcare through hard work and compassion, and appreciation of each other’s differences is what makes the training here truly enjoyable.

Ongoing clinical trials

As medical residents, we understand that despite a strong passion for what we do, work fatigue can take over. Therefore, our program works actively to make sure wellness is a vital component of our day to day responsibilities. 

Firstly, we strive to ease the transition of new interns into residency life by the creation of the “Big-Brother/Big-Sister” program whereby senior residents serve as both work and life mentors to their juniors. Our program supplants work weeks with open-feedback such as “Team Huddles” whereby anyone in the team can express regular workflow feedback, whether seniors to juniors and vice versa. Regular “Town Halls” with the Chief Residents allow residents to receive regular residency updates, express concerns, and have regular interaction. Access to the hospital’s Goldstone Caregiver Center allows residents to find a quiet spot to clear their mind in a calming and relaxing atmosphere. 

For wellness outside of work, Danbury Hospital internal medicine boasts weekly Soccer games held in a local sports dome where faculty and residents can apply a new kind of teamwork. We also host yoga sessions at a local studio. Holiday parties such as our annual Halloween Costume event, winter Holiday Gala, and spring Family Feud challenge bring residents together [temporarily on hold given COVID-19]. Our Wellness Committee is dedicated to easing daily workflow by constantly making improvements. Most notably, our program functions on transparency and support in a close-knit environment. 

Aside from the aforementioned, our Wellness Initiative includes the following:

  • Peer-to-peer support networks
  • Direct faculty mentorship
  • PACT - Physician/Associate Care Team peer supporters trained to effectively provide support 
  • Ride Service for Post Call Days
  • System-wide Exercise Challenges
  • Invited guest speakers for health and wellness, including Goldstone Caregiver Center
  • Employee Assistance Program (EAP)

How has your Internal Medicine residency adapted to COVID-19 pandemic?

The first case of COVID-19 in the state of Connecticut occurred in our network. Given our proximity to the tristate area, our program anticipated the needs of our residents from the very beginning. Our leadership has been working hard to find a balance between commitment to educational needs of our house staff and our safety.

Our program has been very active regarding COVID-19 management as we were involved in research trials including Remdesivir, convalescent plasma and alternative therapies. We have adapted our floor structure to minimize resident exposure to potential COVID 19 patients when possible. 

From the beginning of the pandemic, we have been mindful of the emotional and psychological stress the pandemic has brought to our residents. Regularly scheduled town halls are held to keep the residents informed about COVID-19 issues and receive feedback about our COVID-19 experiences. Resident wellness is an important part of our program and we have paid particular attention to any impact of COVID-19 to resident well-being.

Additionally, our hospital provided testing for residents following the major wave of the pandemic, including antibody testing. Due to mindful and diligent leadership, the great majority of residents have tested negative. We have a robust jeopardy system and coverage for residents who have an illness that needs to be ‘ruled out’ and of course cover for acute issues not related to COVID.

With the evolving pandemic, our residency leaders are very involved in the institutional response at both our sites and worked hard to find the appropriate balance between patient care and education.

What is the structure of your floor teams? 

The inpatient teams include a resident and an intern along with the attending hospitalist with strictly enforced team and individual patient caps. 

What is the ICU experience like?

The Intensive Care Unit (ICU) is a 20-bed closed unit that cares for critically ill inpatients. The ICU is supervised by Board Certified pulmonologist/intensivists who make teaching rounds on a daily basis. There is also a Coronary Care Unit under the supervision of Board Certified cardiologists.

Do you have night coverage?

Yes, we have a night float system. All interns now rotate as part of the night float team consisting of interns and upper-level residents supervised by attending nocturnists. We emphasize teamwork and mentoring of night float interns by upper-level residents who are part of the night float team.

What is the vacation system?

Each resident has four weeks of vacation divided into two two-week blocks. Vacation requests are taken before the start of each academic year and most requests are fulfilled, especially for significant life events.

What other residencies are offered at Danbury Hospital?

General Surgery, Obstetrics/Gynecology, Dentistry, and Pathology

Is there any opportunity for electives at other institutions?

Yes, our residents are offered 4 weeks of elective each year during PGY2 and 3 as dedicated time for electives at Yale New Haven Hospital or dedicated research time. If a resident choses to complete an away elective at an alternative site, they may arrange to do so.

Is there opportunity to complete a Global Health elective?

Those interested may apply for the Global Health program, a 6 week rotation abroad where you will have the opportunity to experience medicine as practiced in other countries. Established sites include Uganda, Vietnam, Dominican Republic, Haiti, Russia, and China.

Does your health system qualify for the Program Service Loan Forgiveness (PSLF) Program?

Yes, we are a 501(C)(3) facility and our residents may qualify for the PSLF Program.
