    I would highly recommend Dr. Mazzoni. She showed concern for our understanding of the diagnosis, never appeared rushed and made us feel confident that we have a doctor that not only cares, but is knowledgeable. She also made sure to let us know who will perform a recommended diagnostic procedure as well as what to expect from the procedure itself.
