About Dr. Bernard Brannigan


Thank you for considering me as part of your health care team.  I appreciate the gift that after 30+ years in the chiropractic profession I still look forward to treating patients every day and enjoy the challenges that clinical care brings.  I recognize that clinical results are what drive my practice growth.  Beyond the technical application of my skill-set as a diagnostician and physical rehabilitation specialist, my commitment to patients is to give them the information and necessary skills to lead an active life style.  Throughout my career I understand that patient education is paramount in the long term success for any positive clinical outcome.

I completed my undergraduate studies in Biology and Science at East Stroudsburg University in Pennsylvania.  Attended Palmer Collage of Chiropractic in Davenport, Iowa where I received a Doctor of Chiropractic degree.  I was given many opportunities for clinical study within the graduate program and outside in private practice settings. I continue my education in chiropractic orthopedics, neurology and radiology.  Within the chiropractic national and state associations I have served on many committees. Also for many years advised health insurance organizations with credentialing of chiropractic physicians.

Having lived in and served the residents of the South Shore for over 30+ years my roots have grown deep here.  I started in private practice in 1986, with my first practice being in Norwell, Massachusetts.  In 2007 my practice expanded with the opening of our Abington clinic. 

I have been fortunate to mentor many intelligent staff members through the years.  Surrounding myself with practitioners’ and staff members who hold the same commitment to excellence as I.  The varied education background and life experience of myself and my staff members allows us to deliver the diversification of services that is now offered within our clinics. I have evaluated many new technologies and techniques and include them within the practice; only when they have demonstrated clinical success.  My professional goals are to provide the best care in a comfortable atmosphere as possible.  I believe you will see that when you enter one of our clinics.  These reasons and many others have allowed my practices to experience continued growth.  Please take the time to explore our website.  If you have further questions regarding our practice or services, please reach out and call or email us.  I hope that I and my staff have the opportunity to be of some help and serve you in the future.  Look forward to meeting you.
