### What this licence is

**Licensed Professional Geologist** is one of the 264 licence categories
the Illinois Department of Financial and Professional Regulation issues, under
the Geology. Practising a regulated profession without a current
licence is an offence in Illinois, which is why IDFPR publishes this register
