Dr Carolyn Choy

Treasurer

Dr Carolyn Choy is a highly skilled Cosmetic and Laser Doctor, founder of Ultimate Aesthetics with over 25 years clinical experience in both general practice and the cosmetic and aesthetic field. Since graduating from medicine from the University of Western Australia, she has devoted her time to being a general practitioner and a cosmetic physician.

In her early times in the hospital, she realised how much she loved all aspects of medicine but also working with her hands and after leaving the hospital, working in the emergency departments and surgical departments, she pursued her first fellowship in general practice. She attained her Fellowship in General Practice. She continued with further educations, attending conferences, and felt called to move beyond general practice and realised that there was a real social need where men and women of the world were constantly being disempowered and by helping people improve their outside appearance by doing a few minor procedures, this so greatly improved a person’s self-esteem.

Helping people see how beautiful they really are within. Feeling beautiful allows us more easily to connect to joy, life and all its possibilities. With that goal in mind, she continued to in her pursuit of excellence to be able to master advanced injection techniques and laser treatments. She understood how scarring could be so soul destroying and has specialised in various techniques to help improve specifically acne scarring and keloid scarring. In that time, she has continued to grow and learn and attained a second fellowship, this as a Fellow of the Cosmetic Physician Collage of Australia.

She has enjoyed growing her team of doctors and nurses and therapist, all with the same mind set, of helping all of us age with grace, with minimal downtime and with the greatest effect of natural looking beauty or as we say, “believable beauty.”
