Toparovsky lives and maintains studios in Los Angeles and near Lake Como in northern Italy. Working in bronze and cast iron, he has created panels, figures and objects from nature as elements for installations that include water and landscapes. With this work he has designed private gardens as well as large scale public art projects.

Simon's art has been exhibited internationally and purchased for important collections including the Museum of Modern Art and the Metropolitan Museum of Art, and Los Angeles County Museum of Art.

In the spring of 2000, Simon was commissioned to do the main altar Crucifix for the new Our Lady of the Angels Cathedral in Los Angeles. The piece was cast at the American Fine Arts Foundry in Burbank and was installed for the consecration of the church in September 2002. Toparovsky is currently working on garden installations in Italy and California and has recently finished a commission for a private altar crucifix. He will have a public exhibition sponsored by the City and Province of Milan (Italy) in April 2003
