My mission is to provide compassionate care for patients in challenging times.

It is a privilege and an honor to stand alongside patients and their families during some of the most difficult times they may face. I strive to provide thoughtful, effective, and compassionate care while maintaining clear and honest communication throughout the treatment and recovery process in the ICU. So you can get to know me, some of my hobbies include Dodgers baseball, music, gaming, and exercise. I also enjoy traveling around the world with my lovely wife.

My goal is to provide compassionate and equitable medical care to patients seeking care for breast-related concerns, including but not limited to breast lumps, abnormal screening mammograms, benign breast masses, and previous or current breast cancer diagnoses. 

I am a graduate of the Tufts University School of Medicine Physician Assistant and Masters in Public Health dual degree program. I have been working at the Dana-Farber Cancer Institute/Brigham & Women’s Hospital Division of Breast Surgery since June 2021.

It is my priority to provide care to patients that is skilled and supportive. I strive to accommodate a patient’s unique and individual needs such that all patients feel cared for and well-informed. I have professional interests in patient-oriented outcomes research and have studied coping and psychosocial wellbeing among adolescents and young adults with cancer. I am originally from Western Massachusetts, and my hobbies include hiking, skiing, and spending with family, friends, and my dog.  

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. 

My treatment philosophy and focus is to diagnose and treat patients ages 15 – 100 whom have a variety of breast issues including but not limited to infection, pregnancy related breast issues, genetic risk for cancer, abscesses, skin disorders, abnormal breast imaging, breast lumps, and past or current personal history of breast cancer.

I've been an RN since 1981, working in Internal Medicine, Oncology, and Ventilator Care. I've been a NP since 1996. I'm a graduate of Columbia University in Adult Health and Oncology. I worked in New Jersey for 20 years in Internal Medicine and combined Oncology prior to relocating to Massachusetts in 2003.

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.

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.

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

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.
