After having graduated from University of Adelaide, Dr Tirza Harley moved to Jindabyne NSW to develop her skills in Emergency Dentistry and snow skiing. When the snow melted, she felt it was time for a new challenge and began work on Collins Street in Melbourne.

Throughout her time in Melbourne, Dr Harley spent many hours continuing her professional development in Orthodontics, both in Australia and internationally. While Dr Harley is not a specialist orthodontist, she is passionate about Early Intervention Orthodontics, and is continually undergoing further study to understand how she can best care for her orthodontic patients. She has been teaching clinical skills in orthodontics over the past couple of years to her colleagues. Lately she has become particularly interested in using her orthodontic knowledge and the latest technology to provide Invisalign to both her adult and teenage patients.

Dr Harley later moved across Collins Street to further extend her scope of practice to include beautiful Cosmetic Dentistry including comprehensive restorative care and Botox in order to create fresh natural looking smiles in her adult patients because, she believes, “they deserve confident smiles too!”.

In 2016, Dr Harley moved home to Sydney (much to her parents delight) with her husband Dr Oliver Cvekus to enjoy the sunshine and embark on ownership of Pennant Hills Dental Centre and The Village Dentist, Castle Hill. Since being at the helm, the practices have won numerous awards including the Hornsby Local Business Award, and the national HESTA Aged Care Award.

In addition to orthodontics Dr Harley loves generally treating young patients to ensure they have a great relationship with the dentist from the word go. She believes education and Prevention is the key to a lifetime of smiles. For this reason Dr Harley has developed a Primary Schools Oral Health Program which she presents to numerous local schools on an annual basis. Based on her contribution to dentistry in the local community she personally has been awarded a Fellowship with the Pierre Fauchard Academy in London.

Dr Harley lives locally and in her spare time Tirza is passionate about good food and loves to cook up a feast to bring her family and friends together. She also loves to hit the ski slopes and enjoy the fresh mountain air when given half the chance.
