Yvonne Gahshan

Oral Health Therapist / Sydney University

I'm Yvonne and I have recently joined the team at Dental Focus as an oral health therapist with adult scope, allowing me to treat and care for patients of all ages. I completed my studies in 2022 at the University of Sydney with dual qualifications in therapy and hygiene.
As an Oral health therapist, I am committed to educating patients of all ages about the importance of regular dental visits and tailored home care instruction.  My role allows me to go beyond drilling and filling as I am able to discuss patient's lifestyle factors and daily routines, helping them to formulate a plan that is suitable for them. I believe that empowering patients to take an active role in their dental care is key in establishing healthy smiles.
When I am not in clinic, I enjoy cooking, spending time with family and catching some sun at Sydney's beautiful beaches
