Harry Marget graduated from the University of Adelaide dental school in 1972 and at that time he completed a short training program at the dental school on how to finish certain procedures. On December 25 of the same year he moved to Melbourne and took a position working seven days a week at a conservative dental practice in the affluent Melbourne suburb of Hawthorn. There it was required that the dentist perform all procedures including molar endodontics, molar surgery, and crown and bridge. After a two year training program in Endodontics at the University of Melbourne, he ventured off on considerable overseas trips to learn from Masters in dental procedures from as far afield as the United Kingdom, the United States, and South America to India, South Africa and Israel. Between 1974 and 1994, he opened no less than three dental practices from scratch and built them up to $3 million dollar business. After 3 to 5 years he sold them off at a considerable profit. In each and every case, careful selection of the type of procedures offered, staffing recruitment, training and business management, were the key elements to the success. Since that time he has operated the one dental practice in the family suburb of East Bentleigh, building it up to comprise of 10 surgeries. Currently with a professional clinical roster of 10 general dentists, 3 dentists specialising in oral surgery and implantology, periodontics and orthodontics respectively, 4 hygienists and oral therapists and a resident anaesthetist, he boasts one of the bigger dental practices in Victoria.
