Doran commenced practice at the Johannesburg Bar in 1994 where he had a busy commercial litigation practice before migrating to Australia to take up a position at Blake Dawson in the Insolvency & Restructuring Group in February 2004.

In 2005, he joined Henry Davis York as a senior associate in the Banking & Finance Group.
 
He returned to the Bar in September 2005 and remains in practice as a barrister and a member of the New South Wales Bar Association.

Doran regularly appears in insolvent trading actions, unfair preference recoveries as well as for the Australian Securities and Investments Commission (ASIC).
