The term Renaissance man was invented to describe guys who have so much more going on than the rest of us. Guys so engaged with the world around them that you wonder how they do it all with just 24 hours a day. Guys like Timothy Leistner. Sometimes it seems the Toledo-born Leistner has a finger in every pie. He has a wall full of degrees, including a bachelor's from Ohio University and a master's and a doctorate from Nova Southeastern University, all put to use in his current job teaching at United Cerebral Palsy. He has also taught art privately and currently teaches evenings at the university level, and he recently collaborated with another artist on a series of storytelling workshops for children. When he's not teaching, he's participating in exhibitions from Fort Lauderdale to Fort Pierce, racking up awards in the process. Even when his own work — oil and acrylic paintings, watercolors, mixed-media sculptures, and photography — isn't included in a given show (which is rare), he shows up at openings in support of his fellow artists, many of whom he mentors. Did we mention that he has his own little commercial gallery in Dania Beach, the better to showcase artists he believes in? Hey, ease up, Tim; you're making the rest of us look like slackers.
