Mark Shields, 71, of Chelsea, Maine passed on April 06, 2023 with his favorite caregiver by his side. Mark was such a gift to everyone and was such a blessing at home where he resided. Mark loved to go fishing with his day program staff and loved every single holiday. He had a tree in his room that he would decorate every holiday with and had Christmas lights covering every wall he had. He was such a light in this world and he will be missed dearly.
