I've worked in the pediatric health care field since high school and by the time I went to college, I knew it would be my career. Children are all different, there is no lock and key to the care and respect they deserve. It's been an honor working with so many wonderful patients and their families, especially watching them grow and take on new aspects of life. Outside of work, I love the outdoors, gardening and traveling with my husband.

William Tollefsen, MD is the EMS and MIH Medical Director for South Shore Health. Dual-boarded in Emergency Medicine and EMS Medicine, Dr. Tollefsen works clinically as an Emergency Physician at South Shore Health in addition to his role as EMS Medical Director.

One of few physicians in the country to receive the prestigious "FAEMS" recognition, Dr. Tollefsen is also the Medical Director for OEMS Region IV, serving 61 cities and towns of the Metro-Boston EMS Council. As the current EMS Medical Director for eight municipal and three private ambulance services on the South Shore, Dr. Tollefsen interacts and provides oversight for over 400 Paramedics.

Dr. Tollefsen graduated from New York Medical College and completed residency training in Emergency Medicine at Harvard University, Brigham and Women's, and Massachusetts General Hospital. He completed a fellowship in Emergency Medical Services and Critical Care Transport at the University of Massachusetts, where he worked as an Emergency Physician and Flight Physician for UMASS LifeFlight. He completed an MBA at the Isenberg School of Management at UMASS Amherst, and holds a Master of Medical Science degree from the Boston University School of Medicine.

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 feel privileged to care for patients from age 18 to 95 and beyond. While I base my practice firmly on research-based evidence, I am aware that much is still unknown in medicine and that guidelines evolve over time. Open communication with my patients helps me respect patients' values and health goals.

Outside of work, you can usually find me exploring the beauty of nature with my four young children.
