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.  

I am a dedicated and patient focused physician with comprehensive experience in hospital settings. I hold a great regard for detail, accuracy and follow through and can make decisions in a fast paced and unpredictable environment. I value communication with patient, their families, my colleagues and support staff to provide very best care for our patients.

I believe in the prevention of disease and the promotion of healthy lifestyles for all children through education and dedication to quality care.

I like to treat each patient and family as individuals. I enjoy earning their trust and getting to know them as well as helping to navigate their child’s successes and challenges. I take pride in making sure we have full and open communication in our visits and your visit never feels rushed. My mission is to provide our patients with the best and most comprehensive pediatric care possible from birth until 21 years of age. I adhere to the “Golden Rule” in my life and practice which is the principle of treating others as one wants to be treated. Outside of work I enjoy exercising, horse back riding, and spending time with my family. I am an avid animal lover and we have many animals in our family.

Dr. O'Brien is Medical Director of Maternal-Fetal Medicine at South Shore Health. 

As a Maternal-Fetal Medicine physician, I am dedicated to caring for women and families navigating high-risk and medically complex pregnancies with expertise, compassion, and individualized attention. 

I strive to integrate evidence-based medicine with a holistic approach that recognizes the physical, emotional, and social factors that shape each patient’s experience. 

I am also committed to advocating for equitable healthcare and improving access and outcomes for marginalized and underserved communities.

Being trusted as a physician to treat patients', sometimes life threatening, medical conditions is a privilege and responsibility I thrive to honor every day. Helping hospitalized patients and their families to cope with changes during these stressful times is crucial to achieve better medical outcomes and to improve the well-being of the community as a whole. 

Outside of work, I like to watch soccer, Crossfit training, travel the world and take photographs.
