    Dr KARP is the best physician I have seen in years! He is thoughtful, took the time to educate himself about my situation in advance, was articulate, compassionate, and knowledgeable. It was a huge relief and I feel like I have someone who will really take care of me.

    Dr. Karp was a good listener and took his time reviewing lab results and listing my symptoms and review of my health issue. He explained follow up visits and future lab tests that are needed to move forward with treatment. I was nervous about the visit and his kind, patient, and caring nature helped ease my stress level. I appreciated how I was treated.

    This was my first visit with Dr. Karp. He has a wonderful bedside manner. He did recommend a treatment and when I asked for data on the expected outcomes he said he would provide it. I'm still waiting. I do wonder how doctors can recommend a treatment and not have data on it's potential effectiveness at their fingertips.
