Board Certifications

Internal Medicine

I am a board-certified internal medicine physician dedicated to caring for patients admitted to Memorial Sloan Kettering. I am committed to delivering the highest quality of care that is based on the most current evidence and is rooted in compassion and communication. My team, which consists of residents and advanced practice providers, works in close collaboration with oncologists, other subspecialists, patients, and family members in order to provide the most comprehensive care possible.

Part of my initial training as an internist happened at MSK. From my very first day as an intern here, I was immediately drawn to the institution’s commitment to not only provide excellent and innovative medical care, but also to care for the individual needs of patients and their families. It is that passion to serve the whole person that attracted me to return to MSK.

In addition to my work as a hospitalist, I am trained in the field of medical simulation. Many people ask what simulation is and what is used for. In a nutshell, simulation is a technique that creates a situation or environment to allow clinicians to experience a representation of a real health care event for the purposes of practice, learning, evaluation, and testing, or to gain understanding of systems and human actions. I collaborate with people from other fields and together we use simulation as a safe way to find gaps in current practices and to teach and practice high-stakes, low-frequency events so that clinicians are optimally prepared to face them should they occur. 

Lastly, I am an avid tennis player who dabbled in the professional circuit early in the 1990s. Tennis has been a part of my life since I was a child and it provides a way for me to stay in good health and to make friendships outside the field of medicine.
