Dr. Kostroff is extremely thorough and very caring. She is on top of all patient tests and provides swift results and easy to understand explanations of the results.

I am a current patient of Dr Kostroff since I was diagnosed back in 02. She showed me more compassion and understanding than any other doctor did at my time of need. She is truly a smart, caring and professional Dr. I highly recommend her for anyone with breast cancer.

One of the most amazing doctors and caring individuals I have ever met who takes her time with each patient and makes you know how much you mean as an individual not just as a patient....warm and considerate, I was able to ask as many questions as I needed and her surgical technique was top notch.

I was able to get an appointment almost immediately and the Doctor and her staff were of the utmost courtesy to me. Not only was the doctor compassionate her office manager made me feel like I couldnt be in better hands. Very loyal and very good at what she does. Makes the patients feel a sense of relaxation under the stress we are under. When I was diagnosed with Breast Cancer I was told to seek a second opinion and the doctor and her office manager assured me that I should do that. They were so sincere and caring and I did seek another opinion and in turn returned to her. Bottom line, great doctor and staff.

Dr. Kostroff is a great doctor. She is caring and compassionate. She is also tops in her field and the Chief of Breast Surgery for the whole North Shore/LIJ system. Dr. Kostroff really helped me and was caring and kind at all times, she made me feel at ease throughout a difficult diagnosis. I did think the office staff left a bit to be desired. Dr. Kostroff is the best breast surgeon you could find.
