    Our daughter had ear tubes put in this morning. Dr. Macarthur was professional and friendly. She completed the procedure quickly! I’d highly recommend her and her whole team.

    This truly is a phenomenal hospital, the care concern and kindness shown to my child who was undergoing a procedure and to me the anxious mommy was out of this world. From start to finish everyone we came into contact with was efficient, helpful and understanding! They ensured we were considered and looked after! Well done to all involved!
