About Dr Teh

Since first qualifying as a doctor with a Bachelor of Medicine and Surgery from the University of Western Australia in 1994, Dr Joanna Teh has dedicated her career to pursuing excellence and achieving the best results for her patients.

 

During her hospital residency at Sir Charles Gairdner Hospital, Dr. Teh cultivated a deep-seated fascination with dermatology. In 2000, she embarked on her career, initially working alongside two dermatologists in Perth. It was during this period that she came to recognize her true vocation lay in the remarkable realm of cosmetic medicine. Since then, Dr. Teh has been dedicated to enriching people’s lives, focusing not only on enhancing their physical appearance but also on fostering their overall well-being.

 

After determining her area of interest, Dr Teh gained Fellowships in Cosmetic Medicine from the Cosmetic Physician College of Australasia and Australasian College of Aesthetic medicine. Even today, she never stops learning, attending conferences and seminars to discover the latest, most effective cosmetic treatments.
