Ton Mooy (officially: Mooij) is a son of the Amersfoort city sculptor Maarten Mooij. He learned the trade on the job and became a stonemason at a restoration company. In the early eighties he became involved as a restoration sculptor in the restoration of Sint Jan in 's-Hertogenbosch.

In 1983 Ton Mooy started his own studio, which was later located in the orangery at Randenbroek, the former workplace of Pieter Starreveld.

Ton Mooy and his staff were responsible, among other things, for the restoration of the Monument to Queen Emma (The Hague) (2001) and the Stedemaagd (Amsterdam) (2010).

In 2002 he made a series of Gargoyles for Amersfoort. A well-known work is his bell angel, an angel with a mobile, on St. John's Cathedral in Den Bosch, which was given its own telephone number.
