Dr. Willem Gheysen is a Maternal-Fetal Medicine specialist based in Sydney, where he works as a Staff Specialist at the Royal Hospital for Women in Randwick. Originally from Belgium, Willem was drawn to Australia and has built a career dedicated to supporting women through the most complex pregnancies, from diagnosis, through birth, and into the early newborn period. At the heart of his practice is a deep commitment to high-quality, tertiary-level ultrasound, which he believes is the foundation of accurate diagnosis and better outcomes for mothers and their babies.

A passionate researcher and clinician, Willem has led research in prenatal genomics and presented this work at the ISUOG World Congress, one of the most prestigious international conferences in obstetric ultrasound and fetal medicine. Co-founding this practice is the natural extension of that dedication, bringing tertiary-level expertise and genuine warmth together so that every family can experience pregnancy with confidence and care.

Outside of work, Willem loves running, photography, and spending time with his family.

Driven by a deep passion for the miracle of pregnancy and the complex and interdependent relationship between mother and fetus, Dr Rita recognised early in her career that her childhood aspiration to make a difference in people's lives, would come to life through supporting women and families during their reproductive journey.

She completed her specialist training in Obstetrics and Gynaecology in Portugal. During a short observership in Australia, she soon fell in love for the country's multiculturalism and diversity. So, she moved down under to follow her dream. She worked across some of the leading hospitals in Australia and is currently a member of the Maternal Fetal Medicine team at the Royal Hospital for Women, in Sydney.

With a particular interest in obstetric imaging, Dr Rita is a proud founder of Waves Ultrasound for Women, where she is able to do what she loves most: to provide advanced medical expertise with a deeply personalised approach to care.

Outside of her professional life, she is a devoted mother of two. She finds both calm and inspiration in the ocean, finding it a privilege to be able to wake to the sound of the waves.

In her personal life, she treasures time with family and friends and, on a very occasional alone time, finds creative expression through painting as a leisure pursuit.

His particular interests include high-quality obstetric scanning, early pregnancy assessment and detailed gynaecological and endometriosis imaging.

Through Waves Ultrasound for Women, he aims to provide a dedicated ultrasound service focused on expertise, accuracy and compassionate care.
