MaryEllen was an amazing friend and nurse. Her compassion was endless and her skills, top knotch. She never had a lousy word to say about anyone, and continually excused those that had wronged her. She was a sister to me and always reminded me of that, since I have no family on Cape Cod. I simply can't express enough my love for her. She was an angel who had completed her assignment on this earth and I believe she is happy and at peace. Memories we shared will always be held close. My genuine and heartfelt condolences to all in her family. Jocelyn
