Meet The Team

Dr Sam Guirguis began operating his practice from Natural Dentistry in Gordon in 2015. Dr Guirguis graduated in 1989 from Sydney University with a Bachelor of Dental Surgery. Driven by his passion and desire to aid others with their dental health, he went on to achieve his Fellowship of the Royal Australasian College of Dental Surgeons.

Dr Guirguis' extensive career has also seen him training and working across the UK, New Zealand and country New South Wales, owning his own practice, teaching undergraduate students as a part-time Clinical Instructor at Sydney University, and training at the Las Vegas Institute for Advanced Dental Studies (LVI) for five years.

Although highly experienced and enjoying all aspects of general dentistry, Dr Guirguis particularly enjoys working in the areas of comprehensive full-mouth rehabilitation, orthodontics (braces & Invisalign^®), facial aesthetics (injectables and fillers) and treatment for sleep-disordered breathing, snoring and sleep apnoea.

Dr Guirguis finds his role as a dentist particularly rewarding and enjoys assisting his patients in reaching their outcomes whether through optimal oral health or a cosmetic solution to something they have been challenged with. He additionally finds great joy in interacting with patients and working in a fun environment alongside other dental professionals who share his passion.

Dedicated to his professional development, Dr Guirguis is continually keeping up to date with the latest orthodontic treatment and postgraduate education in dental sleep medicine. His commitment to the field of dentistry has also previously seen him complete post-graduate studies in orthodontics, implants and cosmetic full-mouth rehabilitation - allowing him to achieve recognition as one of only four LVI clinical instructors in Australia.

Outside of dentistry, Dr Guirguis has a passion for travelling with his wife and kids, skiing, golf, tennis, good food and single malt whiskey.

Dr Sam Guirguis is a member of the following associations:

• Australian Dental Association
• Royal Australian College of Dental Surgeons

Before moving to Australia, Dr Angela Rigo completed a Bachelor of Dental Science at the Pontifical Catholic University in Rio Grande do Sul in Brazil and practised there as a general dentist for 7 years. During this time, she was mentored by some of the greatest names in dentistry which contributed to the wealth of knowledge that she brings.

Her extensive experience, clinical knowledge and continued education combined allows Dr Angela to offer exceptional oral care in all aspects of dentistry from improving aesthetics, to restoring natural function and providing pain relief.

Though Dr Angela loves all things teeth, she is particularly fascinated in prosthodontics, cosmetic dentistry, oral rehabilitation and Invisalign. Dr Angela is passionate about connecting with people and one of her greatest strengths is her ability to establish a long-lasting rapport with her patients. Dr Angela takes the time to listen to her patients needs and circumstances and makes it a priority to ensure patients experiencing dental anxiety feel comfortable while under her care. Nothing brings Dr Angela greater professional satisfaction than witnessing the improvement her work can bring to patients’ confidence and overall lives.

Outside of her practice, Dr Angela leads a very active lifestyle. She enjoys spending time with her friends and family playing sports such as tennis and hiking. She also loves delving into a good book, especially those that challenge her perspective.

Dr Doreena Kuckreja grew up in Indonesia and completed her Bachelor of Dental Surgery in India before deciding to move to Australia. She has worked as a Dentist across Melbourne and Sydney since 2010.

Having worked all across the country, Dr Doreena believes that exposure to different cultures has helped her build a rapport with patients from various backgrounds more easily. She likes to challenge herself and learn new skills, aiming to provide patients with a high level of care in a relaxing environment.

Dr Doreena has a particular interest in endodontics, restorative work and oral health education. She is comfortable treating young patients and helping them develop good oral hygiene practices.

Dr Doreena finds fulfilment in improving her patients' health and wellbeing, and in turn, their confidence and quality of life. The satisfaction Dr Doreena receives from educating and building long-term rapport with her patients drives her to keep learning and enhancing her skillset.

When not at the clinic, Dr Doreena enjoys travelling and learning about different cultures and cuisines. Whenever she gets a chance, she loves to read a book whilst enjoying a good cup of coffee. Her young boys keep her busy, going for bush walks or trips to the city on the weekend.

Christine is a passionate and dedicated dental hygienist. She helps her patients maintain a healthy mouth through effective preventative treatments, education, and personalised instructions for their oral care at home.

She believes “The best doctor is the one who can intervene before diseases start; so I love being a dental hygienist because I do my best to keep you from the dentist.”

Having teeth checked and cleaned can be unpleasant and scary. Yet they are necessary and important procedures to benefit your oral health and overall wellbeing. Christine is very gentle, patient and caring and will clean and polish your teeth to let them shine again.

“When I am doing this work, I am so concentrated in the details that I almost meditate. Patients are often involved in my tranquilising vibe and feel relaxed and often fall asleep.”

​Her qualifications range from Bachelor of Oral Health, Bachelor of Pharmaceutical Science, Master of International Public Health and Master of Interpreting & Translating. In 2010 she received a Dean’s Merit Award. She is a Registered dental hygienist and member of DHAA.

Now also a busy mother with 3 young children, Asher, Chaya and Micah. “Children teach me so much and help me become a better person and give me the most wonderful joy and love; I do everything with them”.

In her spare time, she likes to read, practice Chinese calligraphy and sing in a Christian choir. Her next goal is to study a bit more in traditional Chinese Medicine and use that to serve her dental patients better.
