    Since I am seeing this provider as a participant in a study she is conducting,I find her to be very supportive and responsive about keeping me up to date about the progress of the study.

    I feel that I have a steady health partner in Dr. Kozberg. The "wait and see" approach to certain conditions can be harrowing, and my mind can get creative in its thinking about it, but that worry has been greatly reduced through Dr. Kozberg's empathy and listening skills. Even her staff have been helpful in pushing me to put my health first!

    Kind understanding knowledgeable

    My medical situation is complicated by the fact that the disease itself is not well understood nor is there a cure. Dr. Kozberg was level, measured, specific and extremely informed, and in spite of all the uncertainties I felt that I had a partner in dealing with this illness and in keeping myself alert rather than anxious. She was an enormous help, and very steadying.
