After graduating from the University of New England in 2002, Purser relocated to Brisbane to undertake articles with a specialist family law firm. She was admitted in Queensland in 2004, and practiced family law for approximately 12 months before moving to Tamworth and being admitted in NSW.

Whilst in Tamworth, Purser practised family law, conveyancing, and wills and estates. However, upon joining de Groots in late 2006, she decided to focus her expertise on succession law and, more specifically, estate planning.
