Our Residents

The Chief Medical Residents are a major force in our residency training program. In addition to scheduling conferences and speakers at grand rounds, they are an invaluable resource for teaching, conducting rounds, disseminating medical literature and overseeing administrative and educational aspects of the program. Through the initiatives of the Chief Medical Residents, new program improvements are proposed and accomplished.

The 2020-21 Chief Residents are:

Name: Frederick Rozenshteyn
From: Fair Lawn, New Jersey
Medical School: Tufts University School of Medicine

I am originally from North Jersey and moved to the Boston area to attend Brandeis University where I majored in Biology and minored in Health Policy. I also played NCAA tennis during my college years. Following college, I decided to stay in the Boston area and attended Tufts University School of Medicine. During medical school, I searched out fields that struck a balance between working with my hands and using my mind to solve interesting cases, and in my clinical rotations immediately gained a passion for internal medicine and ultimately gastroenterology.

During the Internal Medicine Residency interview season, I wanted to find a program that would allow me to explore the various subspecialties within Internal Medicine, while also providing me with a well-balanced education. I also knew that I wanted to move back closer to home, specifically to New York City, a place with an incredible diversity of patients, medicine and culture. When choosing between programs, I looked for a place where residents were supported by faculty and worked in collaboration with other housestaff, rather than competed against each other. I quickly found that MSBI fulfilled all these criteria, and offered the opportunity to continue my education in an incredible part of New York City, working with a strong and supportive faculty as well as alongside an enthusiastic and reliable resident group. I have thoroughly enjoyed my training at MSBI and upon completion of my Chief Resident year, I hope to pursue fellowship in Gastroenterology.

Name: Isabel Guerrido Martínez 
From: San Juan, Puerto Rico 
Medical School: University of Puerto Rico- School of Medicine  

I was born in San Juan, Puerto Rico where I received my undergraduate education at University of Puerto Rico-Río Piedras Campus majoring in Molecular Biology and graduate education at University of Puerto Rico- School of Medicine. During medical school, I was exposed to a clinically challenging patient population at Puerto Rico's largest hospital center. I was privileged to serve such a complex patient population and realized I wanted to continue serving this population while seeking to represent Hispanic culture in the United States.  

I knew I wanted to complete residency in New York given that I wanted to experience both cultural and clinical diversity that I would not experience back home. I wanted to become part of a program that would not only provide me with excellent clinical education and exposure to subspecialties but also with lifelong colleagues that I could trust and call my friends. When interviewing at Mount Sinai Beth Israel, the first thing that caught my attention was how welcoming the residents and faculty were. Everyone was smiling, joking and speaking highly of the program. During residency, I have made some of the most memorable relationships with both my patients and my co-residents while receiving excellent clinical education. Without a doubt, MSBI has granted me with the most fulfilling years of my short career as a physician and has given me the tools needed to continue progressing on both the personal and professional level. I am currently a Chief Resident and look forward to continue working with house staff and program leadership to continue improving the Internal Medicine Program. Upon completion of my Chief Resident year, I am hoping to pursue a career in Gastroenterology.  

Name: Ryan Leibrandt
From: Atlanta, Georgia
Medical School: Medical College of Georgia

I’m from Atlanta, Georgia and did my undergrad at University of Georgia where I majored in Biology and minored in Spanish. Before attending medical school, I worked as a Research Study Assistant at Memorial-Sloan Kettering Cancer Center. It was here that I developed my passion for medicine and decided to pursue a career in Oncology. I also loved living in New York City during this time thanks to its unparalleled access to culture, food and entertainment. I returned to Georgia for medical school but always knew that I wanted to return to New York City for residency.

During the interview season, I spoke with a graduate of my medical school who was a current resident at MSBI. He spoke very highly of the program and I was able to see first-hand on my interview day what he was talking about. There was a strong sense of camaraderie among the residents and it was obvious that program leadership was invested in their professional and personal growth. For these reasons, along with its unparalleled access to a diverse patient population in Lower Manhattan, I ultimately chose MSBI. This program has afforded me a well-rounded education in internal medical that I will carry with me for the rest of my career. After completion of my Chief Resident year, I hope to pursue a fellowship in Hematology/Oncology.

Despite the demands of residency training, there is still an opportunity to become involved in extra-curricular activities and have a personal life. And at Mount Sinai Beth Israel we value input from our housestaff on a variety of subjects including scheduling, curriculum and operations. Your life as a resident is not a one-dimensional experience; there is time to give back, time to explore New York City and to make lifelong connections.

Housestaff Council and the Importance of Resident Feedback

A peer-elected Internal Medicine residency housestaff council meets once a month with the program leadership during noon conference to explore new ideas and problem solve. The council may bring any issue to the table for collaborative discussion. All PGY classes are represented on the council including preliminary interns.

Resident feedback about all aspects of the program is regularly sought and highly valued and the agenda for the meeting is entirely resident driven. Housestaff input and feedback is considered and incorporated when new initiatives or policies are considered.

As an example, we have an anonymous "online suggestion box" web survey, through which housestaff can express views or concerns. This survey is checked weekly, and new submissions are discussed by the chief residents and program directors at their weekly cabinet meeting.

Institution Level Involvement of Medical Residents

We encourage our residents to take advantage of the chance to help shape the institution they are training in. Many of our residents sit on institution-level committees, placing them at the table with hospital leaders and giving them opportunity to provide direct resident input into various initiatives. Institutional committees that medical residents sat on during past years included: Blood Utilization, Cancer, Code/RRT, Ethics, Lesbian/Gay/Bi-Sexual/Transgender Health, Patient Safety, Medication Error, Beth Israel Medical Board, Graduate Medical Education, Quality Performance and Improvement, among others.

Community Involvement

Our residents have the chance to serve the New York City community in multiple ways beyond traditional rotations. Our medical residents have regularly served as volunteer doctors at the New York City Marathon, providing care to runners in the finish line medical tent. Residents have also staffed blood pressure, HIV and colon cancer screening booths at community events. Our program offers a unique elective in Lesbian, Gay, Bi-Sexual and Transgender Health, in which residents spend time learning and providing care at the world class Callen-Lorde Community Health Care Center in the Chelsea section of Manhattan.

Life in NYC

Our location in lower Manhattan offers innumerable activities for time away from work. Virtually everything you will need on a day-to-day basis will be within walking distance from where you live. For longer trips in the city, you absolutely don’t need a car, as our public transportation system is fast, reliable and very safe. Cyclists will find lower Manhattan to be extremely bike friendly, with dedicated bike lanes throughout the neighborhoods that surround Mount Sinai Beth Israel.

Restaurants and shops abound within walking distance in our immediate neighborhoods of Gramercy Park, Union Square, and the East Village. Union Square, a few blocks from the hospital, has a Whole Foods store, a Trader Joe's, and an enormous multi-level Barnes & Noble bookstore. Nothing like writing up a case report or research project on your laptop overlooking Union Square! In addition, New York City's flagship Greenmarket, a collection of vendors selling fresh produce and other foods from local and upstate farms, is found in the center of Union Square.

With a little research (check out Time Out New York, Yelp, New York Magazine, or City Search) even a couple of hours off can become a wonderful dinner at a tapas bar, a trip to a wine bar, or a Broadway show. A short subway ride can result in a stomach full of fantastic, truly authentic Indian or Pakistani food in Jackson Heights, Queens, or a complete cultural immersion experience in the peaceful and fascinating Russian neighborhood of Brighton Beach in Brooklyn.

Like the outdoors? Well, this isn't Colorado of course, but there are plenty of options. A peaceful or active day in Central Park cures many woes and people have been known to actually forget they are in New York City after a few hours (granted there have been no randomized trials for this, but we draw this conclusion based upon good, anecdotal evidence). Ninety minutes north of the city is the Mohonk Preserve, home to spectacular hiking. Some of the best rock climbing in the country, and an exceptionally cool town, can be found in and around New Paltz, NY, also just 90 minutes north of Manhattan.

For those of you who crave the beach, Jones Beach and Robert Moses State Park are all just a short way from the city and make nice day trips.
