Dr Jimin Cha (Renmark)

Dr Jimin Cha graduated with Bachelor of Dental Surgery from the University of Adelaide. Dr Cha joined our team in 2015, currently working in Neni’s Renmark Dental Clinic.

Dr Cha takes great pride in providing the most tailored, caring and reliable dental service for her clients that suits the best for a patient’s financial status and longevity of treatment. She focuses on holistic dental management as she treats patients, not just teeth. Dr Cha has been building a good rapport with existing patients and new patients of the local town since she joined our team.


Dr Cha has received positive feedbacks from her patients for her practical approach of dentistry that includes cosmetic dentistry (tooth whitening/front teeth fillings), restorative dentistry, gum treatments, extraction, prosthetic dentistry (crown/bridge/denture), and root canal treatment. She also has built exceptionally good reputation from her patients for her gentle dental procedures, in treating elderlies and patients who suffer from dental anxiety or disabilities through her personalized, relaxed, and caring manner.

Dr Gavin Sidhu (Tanunda and Nuriootpa)

Dr Gavin graduated from the University of Adelaide in 2011 and has worked throughout the country before moving to Barossa to join Neni's Tanunda Dental Centre Team.

Dr Gavin's key philosophy with dentistry is to ensure that his patients are relaxed and at ease in his hands. He works with his patients to address their dental concerns, coming up with plans that help achieve a radiant smile.

Dr Gavin has an interest in helping the less fortunate. He has worked with 'Closing the Gap' to reduce the health disadvantages faced by Indigenous Australians, having done many stints in various Aboriginal and Torres Strait Islander communities throughout the country. In 2015 Dr Gavin was part of a Dental Aid Volunteering Mission to Uganda and Africa helping to put back the smile on many children's faces.

When he is away from the Dental Chair, Dr Gavin's love of the outdoors means a perfect weekend for him in hiking and camping throughout the National Parks of SA.
