My goal is to provide compassionate and equitable medical care to patients seeking care for breast-related concerns, including but not limited to breast lumps, abnormal screening mammograms, benign breast masses, and previous or current breast cancer diagnoses. 

I am a graduate of the Tufts University School of Medicine Physician Assistant and Masters in Public Health dual degree program. I have been working at the Dana-Farber Cancer Institute/Brigham & Women’s Hospital Division of Breast Surgery since June 2021.

It is my priority to provide care to patients that is skilled and supportive. I strive to accommodate a patient’s unique and individual needs such that all patients feel cared for and well-informed. I have professional interests in patient-oriented outcomes research and have studied coping and psychosocial wellbeing among adolescents and young adults with cancer. I am originally from Western Massachusetts, and my hobbies include hiking, skiing, and spending with family, friends, and my dog.

Dr. Suniti Nimbkar, Medical Director of the Breast Care Center at Dana-Farber Brigham Cancer Center at South Shore Health

I'm a surgical oncologist, and the Medical Director of the Breast Care Center at Dana-Farber Brigham Cancer Center at South Shore Health and an Instructor in Surgery at Harvard Medical School. I received my Doctor of Medicine degree from Boston University School of Medicine and completed my General Surgery residency at Boston University Medical Center.

My mission is to provide outstanding, compassionate care for patients with breast cancer which integrates multi-disciplinary care and allows for the most up to date treatment standards. 

I went into the field of breast surgery because I knew that I wanted to be able to help patients going through a new diagnosis of breast cancer with thoughtfulness and insight into the latest therapeutic options.  I feel that being a part of the team at the DFBWCC Cancer Center in clinical affiliation with South Shore Health allows me to be a part of a team of superbly talented clinicians who all have the same goals in mind when it comes to the care of a patient with breast cancer – personalized care, compassion, mutual respect and attention to details.
