Claire was employed as a Supervisor of Customer Services with the United States Postal Service and retired with over twenty years of service. Prior to that, Claire worked in the healthcare industry as a licensed practical nurse at the former Mattapan Chronic Disease Hospital for several years.

Family and friends speak mostly of Claire's infectious smile, sense of humor, quick wit, and authenticity. She enjoyed anything involving needle, thread, and yarn. Claire would often be found putting together a blanket or sweater for an unsuspecting loved one.

Most of all, Claire was devoted to her sons and cherished granddaughters, supporting all their many activities and accomplishments.
