About Wahroonga Family Dental Centre

In stark contrast to many dental practices who offer quick fixes and cosmetic solutions, our dentists are invested in the long term oral and overall health of each and every one of our patients. Our modern and inviting practice is located in the leafy suburb of Wahroonga, just a short walk away from the train station.

Dr Alfred Tsang

Hi, my name is Alfred Tsang and I have been a general family dentist for over 15 years and completed my studies at the University of Sydney….

I believe that we live in exciting times in dentistry as there have been great treatment advances in recent years.  For example, in the past, crown work used to take multiple appointments, but these days the treatment can now be completed in one appointment.  Improved understanding of the biological processes affecting teeth and jaws have greatly changed the way we provide treatment – preventive or interceptive treatment to avoid problems is now the norm rather than the exception.

My particular interests in dentistry are in orthodontics restoration, and CAD/CAM dentistry and I have invested significant time in post-graduate seminars and courses in these areas.

I am married with two boys and in my free time pursue my photographic and musical hobbies.

Dr Andrew Freelander

Hi, my name is Dr Andrew Freelander and after graduating from Sydney University and working in a number of practices I have been in Wahroonga since 1984.

During this time, I have been fortunate to experience an enormous change in the way that we do dentistry. Today we have available a range of techniques which allows us to do the type of dentistry which was only dreamt of when my father (who was also a dentist) graduated. This has required a continual commitment to attending seminars and updates so that we can provide the best of modern dentistry with well researched and proven treatments.

I believe that our patients will be most happy with their treatments if we can form a dentist/patient partnership to work out what is best in your particular circumstances. We have always invested in new materials, techniques and equipment with the aim of providing optimum dental treatment in a caring environment.

On a personal note, I am married with three daughters and in any treatment, I feel that the best question to ask is ‘what would I do for my family in this situation?’ This is the final test of anything that we do for you.

dental hygienist lisa


Lisa spent most of her childhood overseas before moving to Australia when she was 18. After graduating with a Bachelor of Medical Science in Sydney, she moved to the Central Coast where she completed her Bachelors in Oral Health at Newcastle University in 2008.

Prior to this Lisa worked as a casual dental assistant on weekends and the encouragement that she received prompted her to pursue the aforementioned Oral Health degree. Upon graduation, she began her career in the regional town of Tamworth as a Dental Hygienist where she worked for a year before moving to the Sunshine Coast to work for a specialist periodontal practice. It was in this practice, under the supervision of Dr. Vince O’Rourke, that Lisa gained valuable clinical exposure on the topics of periodontal/gum diseases, their diagnoses, treatment planning and implementation, as well as ongoing active management and follow-up.  Due to family commitments, Lisa decided to move back home to Sydney and is currently at Wahroonga Family Dental.

Lisa is married with an adorable three-year-old son. Her hobbies include reading, cooking, gardening, and walking along the beach with her little one, or taking him to the local parks and playgrounds.

What does our hygienist do?

Lisa’s role is to work alongside Dr Freelander and Dr Tsang in order to tailor individual preventive dental programs according to the specific patient requirements. This can include the use of the latest diagnostic utilities such as dental X-Rays, intra-oral cameras for dental photographs, and dental study models.  Information obtained can then be used to devise the appropriate treatment plan such as teeth scaling and polish, application of fluoride treatment, making customised mouth guards for contact sports, dietary counselling, smoking cessation programs, as well as oral hygiene education in order to help prevent dental problems.
