My Philosophy

Dr. Sheldon decided to specialize in radiation oncology primarily because of the day-to-day interactions with patients. The latest knowledge in biomedical science and technology is applied to best use for a particular patient, in a particular circumstance, with a particular perspective and set of values. Every patient is unique. Every day is a new challenge. It is invigorating work and a privilege to perform.


In addition to his clinical passions and an opportunity to pursue them at the Mass General Cancer Center at Cooley Dickinson Hospital, Dr. Sheldon wanted to return to western Mass. because of his genealogical connections to the area – and to Cooley Dickinson – that date back to the mid-1600s.

My eighth great-grandfather, Isaac Sheldon, was one of the first settlers of Northampton. My seventh great-grandfather, John B. Sheldon, helped to settle the town of Deerfield. Dr. Sheldon recently recently discovered that Caleb Cooley Dickinson, the founder of Cooley Dickinson Hospital, is one of his distant cousins.
