About Us

Our History

Starting our practice in 1989, we have more than 26 years of experience in the local community. We moved to our current premises 16 years ago and the practice has grown from a one chair single practitioner practice to a four chair multiple practitioner practice.

We have seen generations of patients from the Riverland and surrounding areas including Waikerie, western Victoria, and Murrayland districts. There is something special about knowing a family from generation to generation. It is easy to be overwhelmed with pride when a child patient becomes an adult parent and brings his/her child into our practice. This act of continued trust is valued by our entire team, and we take that trust very seriously. No matter the specific dental care needs of each of your family members, we will treat each of you with the dignity and respect you deserve.

Our Philosophy

At Dental Care @ Berri, we aim to help our patients maintain optimum oral health for a lifetime as we believe that maintaining optimum dental health is essential to an individual’s overall wellbeing.

We believe preventing the onset of dental problems and oral diseases is extremely important. Therefore, we have a strong focus on providing comprehensive preventative treatment and implementing dental treatment at the earliest stages of disease development to all our patients, with the ultimate goal to delay or prevent extensive dental procedures and to extend the lifetime of restored oral tissues with as little intervention as possible.

We are dedicated to treat all our patients the way we would want to be treated. The well-being and comfort of patients are our primary concerns, we strive to practice in a gentle and compassionate approach for all our patients.We understand that making a decision about your dental health can be difficult, our dental practitioners will take the time to discuss treatment options with you based on your dental needs.
