    Dr Chee is outstanding She greeted me and my daughter as if old friends. She went on to basically give us a tutorial on protein spikes and anemia explaining it in the clearest terms. Then she related that information to my newly learned condition. Dr Chee was so very attentive to our questions and concerns enough to allay anxiety for the time being. She prescribed blood test for immediately and for 4 months later. She assured me I would hear from her with the results no later than 3 business days. And very important she is the only doctor that has tied together some of a confluence of newly learned conditions. Because of this very successful appointment I know I will receive the best of care from Dr Chee going forward.
