    They wouldn't print out my lab results (claiming that they want to save paper -- Understandable). But they could at least email them to me, but they also refused suggesting that I need to contact my pathology/imaging provider myself! Seriously?! Other doctors/clinic just print/email them out to me just fine. Very selfish and not patient-centred at all. I don't understand why the unnecessary hassle. Besides location-wise, took me ages to find where the place is, and not convenient at all if travelling by public transport.

    Saw Dr James Yun today in Randwick. He took the time to listen to all my health issues, asked many questions to narrow down the cause. Finally he provided a detailed diagnosis that really makes sense and a treatment plan. I feel blessed to have found him. Thank you very much Dr Yun.

    Dr James Yun gave me almost two hours of his time in my first visit to him ,he is a perfectionist who clarified health issues I have been confused about for decades. I cannot thank you enough.

    I had a poor experience with this practice from the first call to the last. I can't recall feeling less cared about by any other doctor or their staff.
