About Me

I am a pathologist. My areas of expertise include breast pathology and cytopathology, especially fine needle aspiration biopsies. Not only is this technique simple, minimally invasive, and accurate, but it can save patients from additional procedures that carry complications and may produce greater tissue alterations. I have performed more than 3,000 fine needle aspirations from the breast, thyroid, head and neck, and other locations on the body where a lump or bump has been felt.
