Dr. Farrell graduated from Sydney University in 1971. Since that time he has been a clinician in private practice in Australia and England. His interests were primarily directed to the treatment of TMJ disorder, although he was very familiar with orthodontic treatment as his father practiced the Begg technique for many years in his Sydney practice.

In 1977 Dr. Farrell moved to England where he studied TNJ disorder as well as running a large multiple practice employing general dentists and orthodontists. From this location he was able to study techniques in both the USA and Europe.

From this educational background he observed the failures of the dental profession to treat both the many patients who have TMJ disorder and the growing children with orthodontic problems and future TMJ disorder. Observation and extensive study of research over the last 50 years also showed that extraction of teeth did not resolve orthodontic crowding and craniofacial discrepancies.

He realised that newer techniques had to be developed to treat patients more efficiently.

Concepts beyond just looking at the dentition were evolved from forward thinking dentists such as Dr. Harold Gelb (USA) and Dr. John Mew (UK) along with many others.

Dr. Farrell holds two worldwide patents for new dental appliances and is developing other innovations in his practice in Queensland, Australia specific to the early treatment of orthodontic problems in children and TMJ disorder in adults. He has lectured in many countries including the UK, the USA, Australia. New Zealand and Indonesia.
