Exhibiting since the 1970s, Mehlman has participated in numerous solo and group shows at venues along the East Coast, especially in New York City, and has frequently exhibited in Italy. He opened Ron Mehlman, Sculptures at Kouros Gallery in New York City in 2003. Other sculptures have been commissioned by private corporations and by city and government agencies in this country and abroad. A native New Yorker, Mehlman divides his time between a studio in Pietrasanta, the famed stone and marble center of Italy, and the Gowanus Canal area of Brooklyn.
