BDSc DClin Dent(Orth) MOrth RCS(Ed) MRACDS

Cath grew up in Brisbane having attended All Hallows’ School. She completed a Bachelor of Dental Science at UQ in 2001. Following graduation, Catherine worked as a General Dentist in Brisbane before accepting a Senior House Officer position at the Department of Paediatric Dentistry and Orthodontics at the University of Dundee in Scotland. During this time, she developed a keen interest in Orthodontics.

How long have you been an Orthodontist?

Since 2007

What inspired you to become an Orthodontist?

I have always loved working closely with children and young adults. Orthodontics appealed to me because it is an aspect of Dentistry that can positively transform an individual at any age. It is a rewarding career and I feel privileged to hold this responsibility.

Favourite thing about working with the ethos team?

Joining a dynamic group of people who genuinely love their chosen work and enjoy making patients at ease during their Orthodontic care.

Most inspiring moment?

Watching my baby smile!

What can a smile say?

Happiness, empathy, love and kindness.

What do you like to do in your spare time?

I enjoy raising my two young sons (ages 3 years and 6 months) and spending quality time with my husband. I am also learning German and I love Orchids.

What’s your favourite song at the moment?

I listen to an outdated variety of old classics, classical and American folk music.

Ultimate holiday?

Hard to beat my 2010 trip to the US South Pole Base as a Dentist where I cross country skied on the Polar plateau at -40degC. And yes, my nose was cold!
