Arts Collaborative Medford presents an opening reception for Bernadette Mary Dineen’s “And Then There Was Light: An Art Exhibition on Grief,” which will be on view from today through Friday, September 6. “And Then There Was Light” highlights the ephemeral science of loss after losing a loved one. The experience of losing someone dear is both universal and unique. Through small works on paper and a collection of original poems, this body of work invites in anyone who is navigating the complexities of grief. During the reception, a candle lighting will take place for those who wish to send a light out to their loved one. RSVP through the ACM website.
