About Us

Dr Steven Tan is an Obstetrician and Gynaecologist with a Medical Practice located in the Mater Clinic, based at the Mater Hospital North Sydney Australia



Dr Tan offers a range of services to look after women . He can do routine pap smears, diagnose STD and other diseases of reproductive organs and perform serious operations such as hysterectomies.



Your pregnancy is an exciting and amazing journey and you can have the utmost confidence in exceptional antenatal care.

Your Visits

Antenatal visits are 4-6 weekly up to 32weeks, every 2-3weeks up until 36 weeks after which visits will be weekly until your baby is born.  At each visit, Dr Tan will check your blood pressure, baby’s position, growth and heart rate. Steven has an ultrasound machine available in my consulting rooms which I will often use during your pregnancy.

Dr Tans priority is to attend deliveries so there may be a delay in your appointment. Please be patient. Remember, the next delivery may be yours!
