We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

I am a medical oncologist who specializes in caring for people with lung cancer. As an active member of the Thoracic Disease Management Team, I collaborate with specialties including radiation oncology, thoracic surgery, pathology, and interventional radiology. Together, we ensure that we provide extraordinary individualized care. My colleagues and I are committed to addressing not only each person’s disease, but also their unique social circumstances, priorities, and beliefs. I am particularly interested in using precision medicine when planning treatment. This personalized approach allows us to provide the highest quality of care all closer to home at MSK Bergen, where I practice.

At all of MSK’s locations, people with lung cancer have a variety of treatment options and, if eligible, can participate in cutting-edge clinical trials. These studies take many forms, but all are directed toward learning more about their disease. MSK is leading the way in using precision medicine to select the most appropriate therapy based on the characteristics of your cancer. One size does not fit all and we take pride in offering each of our patients a comprehensive treatment plan designed just for them.
My research focuses on personalized medicine and using biomarkers to predict a person’s response to a treatment. By identifying these unique targets, we can select treatments that may be more effective. Knowing what the best treatment is for a particular person can minimize their exposure to toxicity from therapies that may be less beneficial to them. I have presented this work both nationally and internationally and continue to collaborate with my colleagues from multiple disciplines to advance this growing field.
I aim to ensure that my patients are an integral part of their treatment team. My goal is for them to feel supported and in control. I will continue my joint research efforts to provide better outcomes and improved quality of life for our patients.
