I went into family medicine in order to have long-term relationships with my patients, and I find this to be one of the most rewarding aspects of my career.  I enjoy working with patients of all ages and working together with multigenerational families.  Outside of medicine, my interests include running, biking, skiing, and travel.  Most importantly, I love spending time with my family.

I am Director of GK Dermatology, PC, in Weymouth, Clinical Associate Professor of Dermatology at Brown University, and Professor of Dermatology at Jundiaí Medical School, Brazil. My practice focuses on Medical Dermatology, Phototherapy, and Laser Surgery. I have authored more than 100 articles and chapters and edited 2 monographs and 3 books.

My mission is to provide comprehensive care and holistic support to patients throughout their cancer journey.

With over a decade of service in healthcare, I have expertise in clinical practice, research, and patient-centered care. I earned my Doctor of Nursing Practice degree from UMASS Worcester. My experience ranges across inpatient and outpatient settings, including hematology, oncology, clinical research, medical/surgical care, and primary care.  Outside work, I enjoy sailing and spending time with my family including our dog Una. 

I feel privileged to care for patients from age 18 to 95 and beyond. While I base my practice firmly on research-based evidence, I am aware that much is still unknown in medicine and that guidelines evolve over time. Open communication with my patients helps me respect patients' values and health goals.

Outside of work, you can usually find me exploring the beauty of nature with my four young children.

My mission is to provide the best primary care for my patients to prevent disease. This includes regular follow up of chronic conditions and keeping patients up to date with routine screenings.

It is a privilege to provide primary care and establish long-term relationships with my patients. I believe that everyone's medical care should be individually tailored, and communication is key to providing excellent care. Outside of work, I love to spend time with family and friends. My hobbies include skiing, quilting and cooking. 

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.
