Dr John Bouhabib:

Dr Bouhabib graduated from The University of Sydney in 1989 and has many years of experience as a dentist. He first came to Petersham Dental Practice as a locum and then was offered a permanent part-time position. He has been part of the practice for about four years now. Dr Bouhabib enjoys being part of a group practice as he believes patients benefit from shared knowledge and experience. He is also able to facilitate timely specialist referrals when required. He works part-time to allow him to spend time with his wife and two young children. This will enable him to join in activities at school such as Reading Groups and volunteer at the canteen.

Dr Bouhabib is available on Tuesday and Saturday mornings.
