Bernie was an engineer with the telephone company for many years before retiring and becoming “busier than ever” while taking care of his beloved grandchildren. In his spare time, he enjoyed being a member of the Auxiliary Police and later reuniting with his fellow drummers in the Misslemen. He was also a dedicated parishioner of St John’s Church in Winthrop.

One of Bernie’s favorite sayings was “it’s all part of the adventure” and he lived that out loud when diagnosed with cancer. Forever a student he was more interested by the treatments along the way than afraid of what was to come. And even in his final days he remained the calming loving support to his family while facing his toughest battle.
