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.

I believe that the relationship between patient and doctor should always be collaborative; it is the providers role to imbue knowledge and guidance, but concomitantly, give the patient agency in a combined decision-making process.

I believe wholly in health equity and the belief that we all deserve a fair and equal chance at leading a healthy life - a chance that should be unfettered by socioeconomic status, culture or creed. I believe that the treatment of an individual should be holistic in approach and because of this, I tend to build deep and lasting relationships with my patients. Even the highest medical acumen is deemed useless without rapport and essential communication with the patient. Having the opportunity to live in many different areas of the world has exposed me to different demographics, cultural settings and clinical maladies. Because of this, I think I am able to provide a unique scope of medicine that can better serve my patients. I have worked in both urban and suburban settings - providing health care to some of our communities most underserved - and I have also provided medical support in the international setting. Prior to medicine, I worked in academic research as a virologist studying Ebola virus. My time doing science research helped further cultivate my love and understanding for disease processes from a fundamental and physiological standpoint, allowing me to better understand and identify treatment modalities in the clinical setting. I originally hail from New York but I have been many places since. I have a vast sneaker collection that only out preforms my record collection, I love riding my bike and I am almost a blue belt In Brazilian Jiu Jitsu. I travel as much as possible, cook whenever I can, and I love staying active with surfing, snowboarding, and running. Occasionally, I even read book here and there, and I love my two cats Roger and Tio.

I am a Cum Laude graduate of Tufts University, and I earned my medical degree at the Tufts University School of Medicine. I completed my surgical residency at New York Medical College, and my urological residency at Westchester Medical Center in Valhalla, NY. I came to South Shore Urology on completion of his residency. I am certified with the American Board of Urology and I am passionate about providing high quality patient care in a compassionate environment.

Having grown up on the South Shore, it is a pleasure to care for patients of this region. I served in the US Navy following medical school and completed my surgical training through the Navy. Following multiple military assignments, I chose to return to the area in order to serve my local community and reside closer to my family. 

My mission as an emergency department physician is to provide timely and excellent care to patients while helping them through what are likely very stressful and difficult emergency situations.

I grew up in southern New Hampshire and attended Providence College in Rhode Island. I then obtained my MD at the University of Connecticut. I completed my emergency medicine residency at the University of Cincinnati and while I loved the Midwest, I always planned to come back to New England and was happy to move to the South Shore. In my free time I enjoy hiking, skiing, and spending time with family and friends.

My mission is to provide patient-centered care allowing our patients to access trustworthy and well-informed care.

My personal philosophy in life is to be kind and compassionate. My background is in adult-gerontology and neurosurgery. I aim to create patient-centered relationships where my patients feel comfortable disclosing any concerns. In addition, I aim to provide open communication. Outside of work, I enjoy volunteering at a local nursing home and a local food bank, and performing in an dance group in ballet, jazz, contemporary and hip hop. I also enjoy hiking and exploring local trails.

My treatment philosophy is to establish good rapport with patients during their difficult moments, and to focus on shared decision-making while working on treatment plans and management of acute issues.

I have been practicing medicine for more than 20 years now. I like communicating with patients while focusing on their medical issues and helping formulate plans to meet the treatment needs. Apart from medicine, I enjoy spending time with my two boys, cooking and baking. I am an avid nature lover and enjoy hiking. Exploring new places brings me true happiness. Yoga and meditation helps me unwind after hectic days. 

It is such an honor and privilege to be a physician.  It has been especially gratifying to devote my career to the field of Hospital Medicine, and to work at South Shore Hospital to help serve my community. 

Being hospitalized is often one of the most challenging and frustrating experiences a person can have. As a Hospitalist, what is so rewarding is that I can use my training and abilities to make such difficult times for people more compassionate and less confusing. 

Outside of the hospital, I love spending time with my wife and young son and traveling.  I also love anything to do with the outdoors and enjoy running.
