My focus is to provide patients with knowledge and insight into their specific health conditions.

I pride myself on taking a patient-centered approach to building effective care plans that go beyond the diagnosis of my patients. I am a certified Physician's Assistant who graduated from MCPHS University, Boston with a Master's of Physician Assistant Studies (MPAS.) My previous experience is in primary care and outpatient cardiology. 

Originally from Western Massachusetts, I moved to the South Shore after graduation. I enjoy spending time with my friends, family, and puppy, Oakes. I am also an avid reader and beach-goer. 

I enjoy getting to know patients and treating the whole person. I focus on preventative care and supporting patients to reach their health goals.   

The doctor-patient relationship is at the center of your health care, and I strive to provide care that is collaborative and inclusive. I have a holistic approach, working with patients to treat the cause of medical problems, and reducing prescription medicines when it is safe to do so.   I am also pro-active, coordinating care and advocating for patients as they navigate the health care system. I enjoy caring for newborns, children, and family members of all ages, as well as helping with stress management and healthy lifestyle changes. 

When not working, I enjoy spending time with my family and my extra-large dog, reading, running, cooking, and playing flute, piano and guitar.  

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.  

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.

My mission is to provide every patient on the acute care surgery and trauma surgery services with the highest quality of care inside and outside of the operating room.

I was raised in Southern California and moved to Boston to complete my undergraduate degree in mathematics at MIT.  After completing general surgery residency in Chicago, I moved back to Boston to complete fellowships in Surgical Critical Care and Acute Care Surgery at the Brigham. I love the outdoors and spend my free time snowboarding and hiking throughout the northeast with my friends and family.

My mission is to teach patients about health prevention and the importance of being proactive and taking active measures to mitigate the risk of future health related problems. 

It is a privilege to be able to be in a career that focuses on health prevention, maintenance, and the treatment of acute and chronic disease processes. I believe that as a nurse anesthetist we should provide our patients with the highest level of care. This care must be individualized and needs to involve the patient as an integral member of the health team. 

When I am not at work, I enjoy spending time with my wife, Ashley, and two boys: Beckham and Preston. We enjoy traveling together and being outside. Besides my family, I enjoy reading, exercising, and playing golf/tennis.

My treatment philosophy is to help educate individuals on their role in disease prevention and develop relationships with patients—working as a team to manage both chronic and acute health issues. I believe that each individual has their own unique set of circumstances that influence their health and working together to overcome barriers is an essential part of providing healthcare. I consider it a privilege getting to know patients and families and always look at the big picture when caring for individuals. Outside of work I love spending time with my family, going to the beach, gardening and hiking. I am teaching myself how to ice skate so I can play hockey with my boys!
