Dr Loula Konidaris BDSc (Melb)

 Dr Loula Konidaris finished her Bachelor in Dental Science from the University of Melbourne in 1989 and Loula is currently studying a Master of Health and Medical Law also at Melbourne Uni.

In 2004 Dr Loula Konidaris set up a family practice with her husband in High Street Malvern.  Two years later, a second dental practice was set up in Glenroy. Loula enjoyed building a good relationship with her patients of which many she still treats at Oakstone Dental today.

In 1998 Loula’s first daughter was born and after taking twelve months off she returned to practice three days a week.

Loula’s second daughter was born in 2002 and after running the Malvern practice for over ten years the decision was made to sell the practice.  This allowed Loula to focus on her family and clinical dentistry, which she offers at Oakstone Dental with great care.

Dr Loula Konidaris was then invited to work with a senior dentist and his team in Sandringham. During her ten years in Sandringham she continued attending courses and refining her skills in all areas of dentistry.  Dr Konidaris also volunteered in the Dental Health Foundation program offering free dental treatment to vulnerable members of the community.

Loula joined a city practice in 2012 where she worked for almost five years before joining Oakstone Dental in a part time capacity.  She enjoys using her skills acquired after many years of practice in a caring and compassionate manner.  Dr Loula Konidaris  also works as a community relations officer and professional consultant at the Australian Dental Association Victorian Branch two days a week.
