In 1998, Dr. Donny graduated from the University of Melbourne, Australia, as a general dentist. His first exposure to Orofacial Myofunctional Orthodontics was in 2001.

He pursued further education in the fields of Dentofacial Orthopedics and Orthodontics, Oral Restrictions, and Orofacial Myofunctional Postural Airway Orthodontics, since 2002 onward, from various multidisciplinary experts of orthodontists, dentists, speech pathologists, osteopaths and chiropractors.

Since 2014, he has also been lecturing internationally in Indonesia, Japan, Australia, USA and Malaysia. In 2017, he co-founded Myofocus Education with Dr. Dan Hanson (as of 1st July 2025, Dr Donny is no longer part of Myofocus Education).

Together, they also co-created the Myofocus Take Off Algorithm, which is still the first ever system of delivering Orofacial Myofunctional Therapy using individualized algorithmic prescriptions. They co-created 180 different prescriptions to train patients in correcting their orofacial dysfunctions.

Dr. Donny is a Fellow of the International Congress of Oral Implantology, a Fellow of the Pierre Fauchard Academy, and a Fellow of the International Academy of Dental Facial Esthetics. He has also received his Post Graduate Diploma in Orthodontics and Dentofacial Orthopedics from the London Dental Institute in the United Kingdom.

As an airway centric myofunctional dentist, he operates two centres in Melbourne, and has now restricted his practice to Early Intervention Orofacial Myofunctional Dentistry, within the scopes of Dentofacial Orthopedics, Orthodontics, Dental Sleep Medicine, and Tethered Oral Tissues. His youngest patient so far was 2 days old, and his oldest was 74 years old.
