Linda Slayton says
Dorothy was an exceptional woman and friend. She greeted all with her gorgious smile and beautiful laughter. She was very inspiring, so much spirit, it was infectious. She was a strong advocate for justice. Never afraid to speak out for one that could not. Unselfishly would help those in need. Never afraid to back down. Strong spirit, loving, and caring. A very good friend. She is deeply loved. I will miss our morning phone calls. Rest in peace my dear friend.
