MOUNTAINSIDE — The family of Matthew Toriello, who died in 2019, honored his life with the dedication November 1 of “Uncle Matt’s Room” at Imagine, A Center for Coping with Loss. The room is home to grief support groups for youngsters ages 6 to 9 who have experienced the loss of a parent, sibling or other family member. Known as the “Orange Group,” these children make up Imagine’s largest group of participants and the group most likely to run a waitlist at the organization.
