    Very inexperienced. Walked in, looked around and asked “do you have any questions?” I had to lead him. Didn’t even turn on computer. Visit was awkward. He did take care of prescriptions

    Dr. Lim is a very nice man. At times he seems hesitant to give me information about several problems. I’m having. My last visit he was very insistent of changing some of my pain medication‘s. I currently have a very good Pain Management program. He suggested a medication for me that when I read about it said that it was for short term use only not for long-term chronic pain. I felt as if Dr. Lim had not looked into this medication completely.

    Very dry doctor that doesn't provide much information and not compassionate at all. He doesn't sound confident and provides no valuable information for my health. Very disappointing

    I am not sure the doctor understands the critical nature of my medical situation. My MRI and radiologist report is outdated over two years. I am having significant issues with my cervical spine and upper lumbar regions.

    Dr Lim was very laidback - it seemed that I had to lead the conversation. I may being unfair in my comparison with my previous PCF - Dr Shieh
