I have special interest in geriatric medicine, cardiology, trauma, and point – of – care ultrasound. Practicing as a GP and an emergency medicine specialist provided me with a great opportunity to understand the value of high-quality primary care services. My focus at Shire Doctors and Dentists is to offer a wide variety of services to address a broad range of medical and health related issues helping avoid unnecessary hospital admission where appropriate.

Dr Koonal Prasad
General Practitioner/Cosmetic Physician

I aim to provide a comfortable, approachable, modern and quality general practice care to my patients. I want my patients to feel heard, appreciated and confident as they leave my room.

Away from medicine, I am an avid fan of the NRL and cricket. I love all things performance automotive and I enjoy prioritising my health and fitness. Music is also close to my heart and I always look forward to any down time with my guitar and ukulele.
