He was born in Arlington, MA to Margaret (Cahalane) and Patrick O’Connor.  A year after he was born, the family moved to Charlestown, where he would spend his formative years.  Dennis graduated from Charlestown High School, Class of 1949, where he loved playing basketball and baseball.  After high school, he served in the US Army for 2 years during the Korean War.  After his military service, Dennis went on to earn his bachelor’s degree from the Bentley School of Accounting and Finance.  Dennis then worked as an accountant with Tucker Anthony in Boston.  He worked there for over 47 years and retired as the vice president of finance.  

In his spare time, Dennis stayed active.  He was an avid bowler, enjoyed long walks and biking, especially on the Cape Cod rail trail.  When he was home, he worked on his crossword puzzles and enjoyed spending time with family.  He was especially fond of the Beechwood Knoll neighborhood, where he called home for many years.
