Our Team

Dr. Gregory Chang

I graduated from The Dental School of Western Australia in 1993.  My first work placement was in the Pilbara for 2.5 years prior to returning to the metropolitan area. Along my journey, I have worked in many private dental practices spanning from Joondalup to Gosnells.

In 2002, I started my own practice in Alexander Heights – The Heights Laser Dental Centre. And in 2021, I started Hepburn Heights Dental Centre. That practice has grown over the past 20 years. We have long-standing team members who enjoy where they work. In 2024, I will solely operate from Hepburn Heights Dental Centre.

I truly believe a happy work environment creates happiness in your day. My focus has always been to deliver general dentistry that the patient wants. In the event that I am unable to provide the treatment, I have built up a specialist referral base to help my patients receive the right treatment. I believe effective communication to get a better understanding of what my patient wants is the key. Armed with that knowledge, radiographic and clinical imaging, it creates a good base to plan an outcome that is suitable for you.

I am quite active in the dental profession with numerous memberships including the oldest dental study group – The Dental Study Group of WA, which was established in 1954, and have served on the committee for several years and was honoured to be their president in 2012. Other memberships are Australian Dental Association, Dental awareness committee 2002-2005, Periodontal Society of WA (2000 – current), Prosthodontic Society of WA (2002- current) and, the prestigious ITI (implant) study group, West Perth Branch.

Aside from my practice, I have a loving partner of 15 years and four daughters. Our children attend the Duncraig campus of St Stephen’s School which is near the Hepburn Heights Dental Centre. Their extra-curricular activities keep us busy!!!

Debbie Halleen

Debbie was born in Darwin, NT and moved to Perth at the age of seven. In 2002 she joined the City of Wanneroo Volunteer Bush Fire Brigade where she went on to complete 10 years of active firefighting. In 2003 she completed her Certificate II in Business and Administration and went on to work 12 years as an administration manager for a mercantile agent. In 2017 she had her son and after taking one year off to be a stay-at-home mum she went back to work in the retail industry to gain further experience in customer service. During her time in retail Debbie found she had a passion for great customer service but missed the office environment. In early 2021 she joined the team at The Heights Laser Dental Centre as Front Office Coordinator where she can continue to provide excellent customer service. 

Debbie enjoys spending time with her husband, son, family and friends. She also has a passion for travelling, good food, wine and shopping.
