    All very good.
    In all of the appointments I have had with Dr. Kim she shows concern for my condition, and she as other employees. Dr. Kim is a professional in all ways and a credit to her profession and this facility.
    Staff are good, however *Dr. Kim seemed rushed - she skipped some exam points because "they weren't needed at that time (already done)" she said. I mentioned some pain in my heel & she Rx'd meds. Instead of my physical having no ded., I was told I had a co-pay because I asked questions.
    I really like the time Dr Kim spends with me
