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 look forward to helping patients and members of our community navigate unexpected and stressful health events with extra attention to the patient and their most immediate loved ones, family, and friends. 

I look forward to providing care and service to the community that my wife and I have called home since 2010. We have two beautiful children who lovingly occupy the majority of our free time when not providing healthcare at South Shore Health.

A former pre-hospital provider, he is actively involved in EMS system design, paramedic education and Critical Care Transport Systems. He works closely with multiple EMS, Fire and Law Enforcement agencies throughout Massachusetts.

His research interests include systems of care, resuscitation, airway management, and paramedic education.

I like to tailor treatment plans based on an individual characteristics. Communication is key and I like to get the patient involved in the decision making. I think this facilitates trust and when patients have trust in their provider, they are  able to manage, treat, and prevent diseases more effectively.

I graduated from Quinnipiac University PA program in August 2005, and started my career as a Primary Care PA. I later transitioned to Urgent Care. I have been practicing as an Urgent Care PA for over a decade and love it. My hobbies include biking, hiking, yoga, exercising, traveling and spending time with my family.
