Northern Beaches Orthodontist Dr Roger Hammond

Melissa Cogle

abroad. I came back to Australia and landed a job with Dr Hammond and his amazing team as a clinical assistant, Receptionist, Invisalign Marketing consultant and then onto Practice Manager. I enjoy travelling, reading, watching movies, swimming in the ocean, and spending time with my husband and our two beautiful kids.

Dr Ashwin

in private practices in and around Sydney for seven years, giving me valuable experience in all aspects of dentistry. After undertaking a number of continuing education courses, I decided to pursue my interest in orthodontics and was lucky enough to be offered a place in the Specialist Orthodontic program at the University of Sydney, providing me with the skills to provide orthodontic treatment to a broad spectrum of patients, with treatments ranging from early intervention to orthognathic surgery. It is vitally important to stay abreast of best practice and new developments within the field of orthodontics, and as such, I try to attend as many conferences and educational events as possible both in person and virtually. I have been certified in the use of both Invisalign and SureSmile, and continue to learn from the best in both disciplines in order to provide the best possible treatments to my patients. Whilst not at work, I enjoy spending time with my wife and family and love anything involving cars and playing music.

Dr Ihsan

(Orthodontics). From a patient myself to Orthodontist, I strive to bring out each patient’s personality and confidence with a smile they can wear with pride. Though many would argue to the contrary, I am not completely obsessed with teeth, but enjoy playing soccer and tennis, as well as critiquing a good cup of coffee or food.


and it has led me to work in many amazing places including Hong Kong. I’ve been working alongside Dr Roger for 7 years now and I feel so lucky to be growing and learning from the best. I have a gorgeous little boy who keeps me busy out of work and we love to take him hiking to new places as often as we can.


of Science and started working as a general dental assistant. This is where I initially discovered my passion for teeth, later evolving into a love for straightening teeth! Previously undergoing orthodontic treatment myself, I believe that everyone deserves a smile that they’re proud of and I look forward to being a part of your journey to a straight and confident smile! On my days away from work, I spend my time weightlifting, watching Korean dramas and cuddling our little Italian Greyhound pup, Pluto. I’m always up for a laugh and instantly love anyone who laughs at my bad jokes!


Wagga Wagga. Since completing my studies I re-joined the OTDX team as a Oral Health Therapist where I look forward to providing oral health care to our patients. I enjoy working alongside a very professional team at OTDX. Teeth aside, I love to keep active in my time away from work, by dancing as well as spending time with family and friends.


on the orthodontic journey. My focus is not just on creating straight smiles but ensuring every patient has a positive and memorable experience! Outside the clinic, you’ll often find me on the badminton court trying to keep fit. When I’m not there, I’m exploring Sydney’s food spots, always on the lookout for new culinary adventures. ”
