Dr Molton gained a wide range of experience in the public hospital system, mostly in Emergency Medicine and subsequently as Registrar in Psychiatry at Royal Perth Hospital (until 1996).

He has worked full-time in this field ever since, and currently in his practice in Adelaide, South Australia.

Highlights of Dr Molton’s career include being a formative, inaugural member of the very first society in Australia that represented doctors practising cosmetic medical procedures: The Cosmetic Physicians Society of Australasia.

Dr Molton has given several presentations at various conferences covering contemporary topics relevant to cosmetic medicine. He has a special interest in light-based therapies and holds a post-graduate Diploma of Cosmetic and Dermatology Laser.

As President, in collaboration and consultation with his peers and colleagues, Dr Molton aims to build upon the work of our College forefathers in maintaining the highest standards for all doctors who practice Cosmetic Medicine through education, benchmarking and continued professional development.

Dr David Kosenko

Vice President

Dr David Kosenko graduated with MBBS from Monash University in 1987 and attained his Fellowship of the Royal Australian College of General Practitioners in 1993. He became a Director of Ti-Tree Family Doctors in 1994, started performing cosmetic procedures in 2007 and founded Impress Cosmetic Medicine in 2010.

He has a diverse experience ranging from acupuncture and injection sclerotherapy in the 1990s to Diving and Underwater Medicine and more recently an interest in general practice dermatology, skin cancer and cosmetic medicine. He has been an examiner to the RACGP, is a current member of the Medical Advisory Committee to Beleura Private Hospital and a clinical supervisor for the Eastern Victorian General Practice Training Program.

He was a member of the CPSA and is a founding member of the CPCA.

He prides himself in honesty and integrity and believes that success comes through doing things to the highest standard, as demonstrated by Ti-Tree Family Doctors being awarded the General Practice of the Year.

He sets up Impress Cosmetic Medicine as a small, bespoke cosmetic practice that specializes in injectable treatments and skin care but his interests in cosmetic medicine are much broader. He is passionate about his work and about cosmetic medicine in general and is horrified by the way that cosmetic medical procedures are at times, portrayed as simple beauty treatments that can be performed without medical supervision.
