Dr Purnima (Nima) Goel


Dental Surgeon

Nima chose to become a dentist because ever since she was young, she has always wanted to make a difference in people’s lives via healthcare. And she is more than glad that dentistry seemed to choose her.

She has accumulated over a decade of experience, both overseas and since moving to Australia in 2017. She is highly skilled in all aspects of general dentistry. But her true passion is seeing the results of smile makeovers, which she achieves by combining her depth of dental skills with either traditional orthodontics or Invisalign.

She loves to see patients of all ages with a particular mastery for helping people troubled by dental anxiety. She achieves this with her personal touch and gentle care and, if necessary, providing treatment under general anaesthetic.

Professional Experience

Outside the Practice

Of course, she loves cooking Indian food, especially desserts, but her favourite cuisines are Mexican, Thai and Middle Eastern dishes.

But she is easily at her happiest, spending time with her family and friends, and loves to organise parties that bring everyone together.
