Our Team

After 30 years of dedicated service to the Sunbury community, Dr Nigel Robertson will retire at the end of 2025.

 

Dr Robertson founded Design Dental Group in 1996 after relocating from Scotland, and since then he has taken immense pride in caring for generations of patients.

The entire team at Design Dental Group extends their heartfelt thanks to Dr Robertson for his leadership and commitment. We wish him all the very best in retirement and hope he enjoys travelling—and, of course, staying in touch.

Dr. Hon Leong is well known for his calm and reassuring manner, making him especially skilled at caring for all patients, even the nervous ones.

 

He provides a full range of dental treatments, including implants, and preventative appointments for adults and children, ensuring each patients care is tailored to their needs.

Hon joined Design Dental Group in 2009 and has since become an essential member of the team.

Outside of dentistry, Dr. Leong enjoys spending quality time with his family and relaxing on the golf course.

Dr. Markewich will be joining Dr. Hon in 2026! Originally from Canada, Morgan has since made Australia home, where she completed her dental studies.

She is known for her gentle approach, clear communication, and genuine care. She is passionate about helping patients feel comfortable and confident in the dental chair, while providing a positive experience for all.

We look forward to welcoming patients to her care as she supports them in achieving and maintaining a healthy smile!

Outside of dentistry, Morgan enjoys staying active with CrossFit and biking, and loves exploring Melbourne with her husband.
