Opening a new art gallery in South Florida might be likened to throwing yourself into a shark-filled tank — the odds are against you. Which makes what Jeremiah Jenner has done even more remarkable. First the photographer survived a lengthy waiting list to snag his own space at Fort Lauderdale's Sailboat Bend Artist Lofts. But instead of using that space as both studio and residence, the way his neighbors do, Jenner did something more daring, as in opening his own little gallery. And with just a handful of shows under his belt, he has established himself as a force to be reckoned with locally. Topnotch artists contribute to his exhibitions, which he hangs with as much attention to detail as any of his competition. And perhaps best of all, Jenner has resisted what must be an enormous temptation to make the gallery a showcase for his own work, instead focusing on attracting and nurturing as many artists as he can.
