What patients say About OCKidney

  • "Dr. Thong is one of the most caring doctor we have ever experienced. She can look at your blood test and tell you so much information and what is wrong and what is right. She calls back when you request the office to ask her to call! She works with our other doctor's and figures out what is best for us and when she says she will call and talk to your other doctor, she keeps her word."

    Raymond Smith

  • "I have been seeing Dr. Dang for a few years now. He is always on time for his appointments. He is always friendly, provides lots of information, and has always listened to my questions, and made sure that I understood his answers. I highly recommend him."

    Ted Donohue (Google Reviews)

  • "I highly recommend Dr. Jabara. He is extremely knowledgeable, personable, patient and compassionate. He understands your specific needs and approach to disease and works with it. He doesn't over-prescribe but at the same time he is extraordinarily thorough. He is interested in the whole patient and not just concerned with renal function. He is by far the best doctor I have ever had."
