I have been privileged to provide primary care to patients for 25 years. I started my career in women’s health, then transferred to Affiliated Medical Groups in Quincy. This practice then transitioned to cardiologist Dr. Lisa Antonelli, where I continued my role in providing comprehensive medical care for primary care patients. This practice then joined Dr. Barry Miller’s oncology practice in Quincy, where I continued with my role providing primary care to the adult population. 

In 2008, I decided to join the medical team at South Shore Medical Center, again as a Nurse Practitioner in the primary care role. I feel that I have been fortunate to provide care for many of my very first patients and their families today. 

Outside of work, I enjoy spending time with my two sons and their families. I also enjoy hiking, kayaking, watercolor painting, and traveling.

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. 

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.
