I enjoy helping people stay healthy through preventative medicine, as well as treating both developing and ongoing health issues. I especially value getting to know my patients over time.

I joined the team in 2015 coming from years of experience as a floor nurse at a Boston-based city hospital. Many elements of my floor nurse practice included disease knowledge/management and wound management.

I enjoy collaborating with my fellow practice physicians to determine the best care options for our patients. In terms of wound care, the mechanisms we use to help a patient to heal are very much individually tailored. This requires that I really know my patient and their level of activity, what they do on a daily basis and any physical or psychosocial elements which can interfere with healing. Knowing my patient's personally helps me to tailor their care and determine elements which would be most effective for healing.

I grew up in Scituate and am a proud graduate of Scituate High School.  After graduating from Harvard-Radcliffe, I continued doing another year of diabetes research at Massachusetts General Hospital, then did two years of breast cancer research at the Dana-Farber Cancer Institute.  I graduated from the Boston University School of Medicine, went to UMass Worcester for residency, graduated from the Harvard School of Public Health, and then went to Brown for residency.  I began working at South Shore Medical Center in 2008.  I especially enjoy seeing patients who knew my father, a police officer in Scituate for 29 years and hearing their stories about him.  I try to motivate, encourage and work with my patients and it is an honor and a privilege to be able to care for them.  Outside of work, I love dancing, playing frisbee, and spending time with my family. 

Being a member of South Shore Health anesthesia department is personally and professionally rewarding. I believe having high standards of care allows for a safe and effective patient experience.

I received my undergraduate nursing degree from Boston College and my masters in anesthesia from Northeastern University. Practicing in the Boston area has been important to me as my children grow. We enjoy our friends and family as well as skiing, soccer and the outdoors.

My mission is to provide compassionate and effective care to treat patients in critical moments in order to ensure the best possible outcomes through prompt intervention and evidence-based practices.

I completed residency at Boston Medical Center. I believe in providing evidence-based and compassionate care at all times and in honest and open communication with my patients about their condition and treatment. Outside of work, I enjoy rock climbing and spending time outdoors and with my family.

As the Medical Director of Addiction Medicine at South Shore Health, I work to tackle the defining medical challenge of our time: Substance use and alcohol use disorder.

In addition to seeing adult patients at South Shore Hospital, I work with colleagues across South Shore Health to develop and implement a comprehensive addiction medicine treatment program. This program will connect patients with the resources they need to manage substance use disorder, no matter if they come to us through the Emergency Department, primary care, or another setting. Additionally, I serve as Medical Director for Spectrum Health System's opioid treatment program, ATS/detox, CSS, and therapeutic community in Weymouth.

Prior to my work at South Shore Health, I helped launch the Bridge Clinic at Boston Medical Center, which connected patients with treatment options for substance use disorder. I also served as Medical Director for Spectrum Health Systems’ Opioid Treatment Program in Weymouth.

In my spare time, I enjoy baseball, reading fiction, snowboarding, and cooking.

As a medical student, I was unsure what my clinical focus would be. Once I saw my first delivery, it was clear that this was my future. I started my internship and residency training here in Boston. After moving to California and spending several years practicing there, I knew I wanted to return to Massachusetts. I have been at South Shore Hospital for nearly ten years now and am grateful to work with the women of the South Shore. After many years practicing both Obstetrics and Gynecology, I realized my true love was the Birthing Unit and transitioned to a Laborist position. I am privileged every day to be part of something so amazing and love that I get to share in such an important family experience.

My treatment philosophy and ultimate goal is to collaborate with families to achieve the best birth experience while helping to ensure the wellbeing of mom and baby.

I started practicing primary care at Boston Medical Center in 2001 and was part of the Faculty of Boston University's School of Medicine. In 2010, I transitioned to the Quincy and Braintree area to continue serving as a primary care physician and urgent care provider. I graduated from the University of Puerto Rico School of Medicine and completed my residency in Internal Medicine at the Hospital of Saint Raphael/Yale-New Haven Hospital.

It is an honor to have patients place their trust in my hands. I strive to provide excellent care throughout a patient’s entire hospital stay, be it in the ED, OR, ICU or ward. Outside of work I enjoy spending as much time as possible outside with my family and friends.
