Mark—such a kind, intelligent and helpful guy. I was just becoming a Peer Mentor at AiCA-SF as he was transitioning out, but he was always "there" for you when you needed him—and he had the best sense of humor. He had such a genuinely sweet way about him, very uniquely so. If there is one thing I can say about him, it's that he will be greatly missed. My thoughts are with his family and closest friends.
